It is known that the silicate particles have a real index of refraction ranging between 1.5 and 1.6 for visible light. However, there is a spectrum of colors associated with samples of volcanic ash, from very light to dark gray. This makes for variations in the measured imaginary refractive index under visible light.[39]

Facts About Mount St

  1. Der Mount St. Helens liegt im Bereich der indianischen Nordwestküstenkultur. Die ältesten Spuren menschlicher Besiedelung sind Feuerstellen, die auf das 5. Jahrtausend v. Chr. datiert werden. In historischer Zeit war das unmittelbare Umfeld des Berges von den Klickitat bewohnt, die weitere Umgebung von den Binnen-Salish. Beide Völker teilten einen Mythos über den Berg, den sie Loo-Wit Lat-kla oder Louwala-Clough (Feuerberg oder rauchender Berg) nannten, und die anderen Vulkane der Umgebung. Wegen seiner ebenmäßigen Form (vor dem Ausbruch 1980) identifizierten sie Mount St. Helens mit dem schönen weiblichen Geist Loo-Wit oder La-wa-la, um den sich die beiden Söhne des „Großen Geistes“, Wy’east (Mount Hood) und Pahto (Mount Adams) stritten. Die beiden eifersüchtigen Männer (Vulkane) warfen mit Steinen und flüssigem Feuer und zerstörten dabei nicht nur Dörfer, sondern auch die Brücke der Götter, eine Felsbrücke über den Columbia River mit besonderer Bedeutung in den Mythen der Indianer, und isolierten so die Region nördlich des Flusses. Der „Große Geist“ konnte erst Ruhe schaffen, als er alle drei in Berge verwandelte.[3]

  5. Plinian Eruption. Removal of the cryptodome and flank exposed the conduit of Mount St. Helens, resulting in a release of pressure on the top of the volcano's plumbing system. This caused a depressurization wave to propagate down the conduit to the volcano's magma storage region, allowing the pent-up magma to expand upward toward the vent opening. .

Mount Lago is a prominent 8,745-foot (2,665-metre) mountain summit located in the Okanogan Range of the North Cascades, in Okanogan County of Washington state. The mountain is situated on the eastern side of the Cascade crest, in the Pasayten Wilderness, on land managed by Okanogan National Forest.The nearest higher peak is Jack Mountain, 19.5 miles (31.4 km) to the west-southwest Sein heute 2539 m hoher Gipfel ragt etwa 1100 m über die umliegenden Bergrücken auf. Der Vulkankegel hat einen Durchmesser von knapp unter 10 km. Der Mount St. Helens liegt vollständig im Einzugsgebiet des Columbia Rivers. Am Berg entspringende Bäche fließen nach Norden in den Cowlitz River, nach Westen über den Toutle River in den Cowlitz, nach Südwesten in den Kalama River und nach Südosten über den Muddy River in den Lewis River oder direkt in diesen ab. Die Niederschlagsmengen betragen im langjährigen Mittel 1150 mm am Fuß bis 3550 mm an den exponierten Hängen.[1]

1980 eruption of Mount St

Superheated flow material flashed water in Spirit Lake and North Fork Toutle River to steam, creating a larger, secondary explosion that was heard as far away as British Columbia,[33] Montana, Idaho, and Northern California. Yet many areas closer to the eruption (Portland, Oregon, for example) did not hear the blast. This so-called "quiet zone" extended radially a few tens of miles from the volcano and was created by the complex response of the eruption's sound waves to differences in temperature and air motion of the atmospheric layers and, to a lesser extent, local topography.[8] Take in the majestic views of the Pacific Northwest's signature volcanic peaks: Mount Hood, Mount Adams, Mount St. Helens, and Mount Rainier. The new edition of this popular guide includes all the information you need, including detailed trail descriptions, directions to backcountry campsites, 65 easy-to-follow maps, permit requirements, and. Die Kaskadenkette verdankt ihre vulkanische Aktivität der Plattentektonik. Vor der Küste stößt die Juan-de-Fuca-Platte auf die Nordamerikanische Platte und taucht unter ihr ab (Subduktion). Das Material der Platte schmilzt in der Subduktionszone und steigt durch beim Zusammenprall entstehende Risse in der Erdkruste als Magma auf. On 20 March 1980, Mount St. Helens awakened from over 100 years of dormancy with a magnitude 4.1 earthquake which began a series of events leading to eruption. Steam and ash eruption started on 27 March and over the next two months the north side of the mountain started bulging at the rate of about 5 to 6 feet a day. Die großen und kleinen Seen des Gebietes waren durch den direkten Eintrag von Aschen stark versauert, regenerierten sich aber schon nach den ersten beiden Wintern. Hangrutsche warfen mehrere Millionen tote Bäume und weitere Biomasse in den Spirit Lake, den Coldwater Lake und andere Seen. Der Abbau der organischen Substanz bewirkte eine massive Eutrophierung, was starken Algenwuchs und eine vollständige Zehrung des im Wasser gelösten Sauerstoffs zur Folge hatte. Im Spätsommer 1980 waren fast alle Stillgewässer am Mount St. Helens umgekippt. Entgegen der Erwartung, dass es Jahrzehnte dauern würde, bis sich der Nährstoffkreislauf wieder stabilisieren würde, reichten bereits die Niederschläge und Temperaturzyklen zweier Winter, um die Sauerstoffversorgung der Seen in Gang zu bringen und die überschüssigen Nährstoffe auszuspülen. Auch 30 Jahre nach dem Ausbruch schwimmen auf den beiden großen Seen noch hunderttausende Baumstämme. Ihr Abbau verläuft aber stark verzögert und die Gewässer verkraften die freigesetzten Nährstoffe.

St. Helens climbing permits will be available for the 2012 climbing season beginning at 9 a.m. Wednesday on the Mount St Helens Institute's website at mshinstitute.org There were also indirect and intangible costs of the eruption. Unemployment in the immediate region of Mount St. Helens rose tenfold in the weeks immediately following the eruption, and then returned to near-normal levels once timber-salvaging and ash-cleanup operations were underway. Only a small percentage of residents left the region because of lost jobs owing to the eruption.[8] Several months after May 18, a few residents reported suffering stress and emotional problems, even though they had coped successfully during the crisis. Counties in the region requested funding for mental health programs to assist such people.[8] Outdoors, visitors can explore Silver Lake along the 0.6 mile-long trail, including boardwalks over the wetland where a variety of aquatic plants and migratory waterfowl can be viewed at different times of the year.

Small international groups and personalized service An earthquake at 8:32:11 a.m. PDT (UTC−7) on Sunday, May 18, 1980[3], caused the entire weakened north face to slide away, creating the largest landslide recorded. This allowed the partly molten, high-pressure gas- and steam-rich rock in the volcano to suddenly explode northwards toward Spirit Lake in a hot mix of lava and pulverized older rock, overtaking the avalanching face. A refined estimate of $1.1 billion ($3.4 billion as of 2018[update][49]) was determined in a study by the International Trade Commission at the request of the United States Congress.[8] A supplemental appropriation of $951 million for disaster relief was voted by Congress, of which the largest share went to the Small Business Administration, U.S. Army Corps of Engineers and the Federal Emergency Management Agency.[8]

Spinnentiere und aasfressende Laufkäfer waren die ersten Tiere, die von außen in die lebensfeindlichen Geröllfelder einwanderten. Sie wurden vom Wind eingetragen und lebten von den Körpern der ebenfalls durch den Wind eingewehten Insekten, die noch keine Überlebensgrundlage fanden. Im ersten Sommer brachte der Wind durchschnittlich 6 Milligramm Trockenmasse an Insekten pro Quadratmeter und Tag,[14] angesichts der Größe des Gebietes waren das schon im ersten Jahr mehrere Tonnen Biomasse, die von den Destruenten umgesetzt wurden. Wapitihirsche nutzten die offenen Landschaften von den ersten Wochen an als Route für Wanderungen und ernährten sich dabei von den aufkommenden Weiden und Rot-Erlen. Yellowstone National Park is a national park in the United States.It was the world's first national park. United States President Ulysses S. Grant signed a law to create it. The name was taken from the Yellowstone River, which flows through the park.Yellowstone was made a UNESCO World Heritage Site in 1978.. Yellowstone National Park is famous for its geysers and hot springs Glacier and snow melt mixed with tephra on the volcano's northeast slope to create much larger lahars. These mudflows traveled down the north and south forks of the Toutle River and joined at the confluence of the Toutle forks and the Cowlitz River near Castle Rock, Washington, at 1:00 p.m. Ninety minutes after the eruption, the first mudflow had moved 27 miles (43 km) upstream where observers at Weyerhaeuser's Camp Baker saw a 12-foot-high (4 m) wall of muddy water and debris pass.[31] Near the confluence of the Toutle's north and south forks at Silver Lake, a record flood stage of 23.5 feet (7.2 m) was recorded.[31]

  1. Am 18. Mai 1980 brach der Mount St. Helens aus. Der obere Gipfel wurde abgeblasen, alles in einem Radius von 8 Meilen wurde ausgelöscht, und Asche fiel über 22.000 Quadratmeilen
  2. Mount St. Helens is found in Skamania County in Washington State and.. The Monument was established in 1982 to designate 445 km2(110,000 acres) around Mount St Helens for research, recreation, and education. Within its boundaries, the area that was impacted by the cataclysmic eruption of May 18, 1980 is left to respond naturally to all.
  3. The Mount St. Helens Visitor Center opened its doors to the public a few years after the monumental eruption of Mount St. Helens. Functioning as a gateway to the mountain, over 30 miles away, our goal is to educate visitors on the historical significance of the landscape before and during the eruption. We also focus on the resulting impact on nearby ecosystems. Our vantage point offers a view of the Western slope of the mountain, visible from both our center and walking trail.
  4. Nicht weniger gefährlich war ein Lahar, der durch Vermischung der pyroklastischen Ströme mit dem Eis und Schnee der oberen Bergflanke und mit einer Geschwindigkeit von 120 km/h für weitere Verwüstung sorgte, so dass die üblichen Hochwasserstände binnen kürzester Zeit um bis zu 9 m überschritten wurden.
  5. St. Helens produced an additional five explosive eruptions between May and October 1980. Through early 1990, at least twenty-one periods of eruptive activity had occurred. The volcano remains active, with smaller, dome-building eruptions continuing into 2008.
  6. The 2004–08 volcanic activity of Mount St. Helens has been documented as a continuous eruption with a gradual extrusion of magma at the Mount St. Helens volcano. Starting in October 2004, there was a gradual building of a new lava dome. The new dome did not rise above the caldera created by the 1980 eruption. This activity lasted until January 2008.

Mount St. Helens ZipLine Adventure

Wegen seines geringen Alters hatten Verwitterung und Erosion nur wenig Zeit, um den Berg anzugreifen: Vor dem Ausbruch 1980 war Mount St. Helens der ebenmäßigste Vulkan Nordamerikas und wurde mit dem japanischen Fujisan verglichen. Mit damals 2950 m war er der fünfthöchste Berg Washingtons und ist dies auch nach dem Verlust von 411 m weiterhin. In the studied area, Cistus species play an important role in the pattern of recolonization of Pinus pinaster stands after wildfire. These shrub species are obligate seeders and pioneers after a fire when they germinate rapidly from a persistent soil seed bank which is stimulated by a thermal increase ( Nèman et al., 1995 , Trabaud and Renard. As the avalanche and initial pyroclastic flow were still advancing, a huge ash column grew to a height of 12 miles (19 km; 63,000 ft) above the expanding crater in less than 10 minutes and spread tephra into the stratosphere for 10 straight hours.[33] Near the volcano, the swirling ash particles in the atmosphere generated lightning, which in turn started many forest fires. During this time, parts of the mushroom-shaped ash-cloud column collapsed, and fell back upon the earth. This fallout, mixed with magma, mud, and steam, sent additional pyroclastic flows speeding down St. Helens' flanks. Later, slower flows came directly from the new north-facing crater and consisted of glowing pumice bombs and very hot pumiceous ash. Some of these hot flows covered ice or water which flashed to steam, creating craters up to 65 feet (20 m) in diameter and sending ash as much as 6,500 feet (2,000 m) into the air.[35] Für die Wissenschaftler war die Regeneration der vom Ausbruch betroffenen Flächen ein herausragendes Forschungsobjekt der Störungsökologie. Der direkte Einfluss von Druckwelle, Aschewolken und Waldbränden einerseits, die unerwartet überlebenden Organismen und die sofort einsetzende Sukzession wurden und werden intensiv untersucht.[15] Überraschend war die Bedeutung von unterirdisch lebenden Nagetieren für die Vegetationsentwicklung. Die Taschenratte Thomomys talpoides gräbt den Boden um und bringt dabei Samen aus durch Asche verschütteten Schichten nahe der Oberfläche, wo sie keimen können.[16] Eine besondere Rolle spielte Kot der Taschenratten für die schnelle Ausbildung einer Mykorrhiza, die das Wachstum der Vegetation förderte.[17] Mount St. Helens is a typical "stratovolcano," the volcanic form most familiar from photographs of their typically conical profiles. The great 1980 eruption destroyed most of the volcanic cone, leaving a huge amphitheater on the north side that is well seen from the Johnston Ridge observatory and visitor center. Volcanic activity in 2004-05 built a new lava dome within this amphitheater, visible from the "VolcanoCam" at the observatory but not yet large enough to replace the destroyed cone.

Mount St Helens maakte toen 57 slachtoffers. De schade was enorm: 200 huizen raakten vernield en een bosgebied van 500 vierkante kilometer ging tegen de vlakte. De vulkaan stortte in tijdens de uitbarsting en was nadien plots 400 meter lager Ascending to 14,410 feet above sea level, Mount Rainier stands as an icon in the Washington landscape. An active volcano, Mount Rainier is the most glaciated peak in the contiguous U.S.A., spawning five major rivers. Subalpine wildflower meadows ring the icy volcano while ancient forest cloaks Mount. Im März 2005 fand eine erneute Eruption von Rauch und Asche statt. Die Rauchsäule war etwa 11 km hoch und war noch in Seattle zu sehen. Am 9. März ging vulkanische Asche im rund 100 km östlich des Berges gelegenen Yakima, Washington nieder. In den folgenden Jahren nahm die Aktivität des Vulkans wieder ab, es kam noch zu kleinen, oberflächennahen Erdbeben und gelegentlichen Dampfwolken. Nur der Lavadom im Krater wuchs bis Januar 2008 durch langsam ausquellende Lava.[10] Im Juli 2008 stufte der USGS den Mount St. Helens auf ruhend und Warnstufe Null zurück.[11] Interactive online tool to view volcano webcams and live seismic recordings side-by-side online.

Der Vulkan Mount St Helens by Lucas Wiedewald on Prez

Das Mount St. Helens National Volcanic Monument wird von drei Seiten her durch Stichstraßen erschlossen. Der Hauptzugang erfolgt von Westen, ausgehend von der Kleinstadt Castle Rock, knapp 100 km südlich der Hauptstadt Olympia am Interstate-5-Highway. Nahe dem Ort am Silver Lake und etwas mehr als 55 km vor der Grenze des eigentlichen Schutzgebietes liegt das Haupt-Besucherzentrum.[18] Es wird von der Washington State Parks and Recreation Commission betrieben, nachdem dem Forest Service im Jahr 2000 die Mittel fehlten, um es weiterhin mit Personal auszustatten. Das zweite große Besucherzentrum nahe dem Parkeingang am Coldwater Lake wurde aus Geldmangel im Herbst 2007 geschlossen. Erst im Frühjahr 2014 wurde es in Zusammenarbeit des Forest Service und des seit 1996 bestehenden Mount St. Helens Institute als Bildungseinrichtung für Veranstaltungen und Gruppen wieder eröffnet.[19] Somit verbleibt im National Monument selbst nur noch das kleine Besucherzentrum am Ende der Stichstraße an der Johnston Ridge. Es enthält eine Ausstellung zur Geologie des Gebietes und der Geschichte des Ausbruchs. Mount St. Helens can be visited as a longish day trip from Seattle or Portland, or more conveniently as a side-trip while traveling between the two cities. Mount Saint Helens (MSH) var anerkjent som den vakreste av kaskadefjellene. Kjegleformet og snødekt tårnet den seg over dype daler med tett skog og en krystallklar innsjø på nordsiden. I mars, 1980, begynte magma å bevege seg opp i fjellet så det splittet seg The first point regards two officially listed victims, Paul Hiatt and Dale Thayer. They were reported missing after the explosion. In the aftermath, investigators were able to locate individuals named Paul Hiatt and Dale Thayer who were alive and well. However, they were unable to determine who reported Hiatt missing, and the person who was listed as reporting Thayer missing claimed she was not the one who had done so. Since the investigators could not thus verify that they were the same Hiatt and Thayer who were reported missing, the names remain listed among the presumed dead.[46][47] Der Katastrophenfilm Dante’s Peak von 1997 mit Pierce Brosnan in der Hauptrolle unter der Regie von Roger Donaldson orientierte sich am Ausbruch des Mount St. Helens. Die Produzenten ließen sich von Wissenschaftlern der USGS beraten und konnten so die Abläufe und Wirkungen eines Vulkanausbruchs weitgehend korrekt darstellen.

Photography - MountStHelens - Photos, Prints & Tip

Angesichts der finanziellen Situation des Forest Services und des Schutzgebietes läuft seit Anfang 2007 eine politische Debatte über die Zukunft des Monuments. Politiker aus Washington und verschiedene Naturschutzorganisationen schlagen vor, Mount St. Helens als Nationalpark aufzuwerten und dem National Park Service zu übertragen.[23] Andere Stimmen fordern ein Ende der Auflagen für Forschungszwecken und die Freigabe des ganzen Berges für die Freizeitnutzung.[24] Am 1. Oktober 2004 ereignete sich ein kleiner Ausbruch. Die Eruption begann mit einer Wolke aus Dampf und Asche, ausgehend von einem Gletschergebiet im Krater südwestlich des Lavadomes. Diese Wolke driftete in Richtung Südwesten. Im rund 60 km entfernten Vancouver, Washington und Wood Village, Oregon wurden Straßen, Dächer und Autos mit einer Schicht aus feiner, schwarzer Asche überzogen. Der USGS befürchtete, dass ein größerer Ausbruch bevorstehen würde. Am 2. Oktober wurde von Messgeräten im Berg aufsteigendes Magma registriert, die Alarmstufe wurde auf den höchsten Wert drei erhöht und eine Warnung vor einem größeren Ausbruch innerhalb der nächsten 24 Stunden herausgegeben.[8] Das ganze Schutzgebiet wurde evakuiert.

More than 4,000,000,000 board feet (9,400,000 m3) of timber was damaged or destroyed, mainly by the lateral blast.[8] At least 25% of the destroyed timber was salvaged after September 1980. Downwind of the volcano, in areas of thick ash accumulation, many agricultural crops, such as wheat, apples, potatoes and alfalfa, were destroyed. As many as 1,500 elk and 5,000 deer were killed, and an estimated 12 million[8] Chinook and Coho salmon fingerlings died when their hatcheries were destroyed. Another estimated 40,000 young salmon were lost when they swam through turbine blades of hydroelectric generators after reservoir levels were lowered along the Lewis River to accommodate possible mudflows and flood waters.[8] A series of large explosions on July 22 broke more than a month of relative quiet. The July eruptive episode was preceded by several days of measurable expansion of the summit area, heightened earthquake activity, and changed emission rates of sulfur dioxide and carbon dioxide. The first hit at 5:14 p.m. as an ash column shot 10 miles (53,000 ft; 16 km) and was followed by a faster blast at 6:25 p.m. that pushed the ash column above its previous maximum height in just 7.5 minutes.[50] The final explosion started at 7:01 p.m. and continued for over two hours.[50] When the relatively small amount of ash settled over eastern Washington, the dome built in June was gone.[52]

A film crew was dropped by helicopter on Mount St. Helens on May 23 to document the destruction. However, their compasses spun in circles and they quickly became lost.[43] A second eruption occurred the next day (see below), but the crew survived and were rescued two days after that. The eruption ejected more than one cubic mile (4.2 km3) of material.[44] A quarter of that volume was fresh lava in the form of ash, pumice and volcanic bombs while the rest was fragmented, older rock.[44] The removal of the north side of the mountain (13% of the cone's volume) reduced Mount St. Helens' height by about 1,280 feet (390 m) and left a crater one to two miles (2 to 3 km) wide and 2,100 feet (640 m) deep with its north end open in a huge breach.[44][contradictory] The flow deposits were still at about 570 to 790 °F (300 to 420 °C) two weeks after they erupted.[8] Secondary steam-blast eruptions fed by this heat created pits on the northern margin of the pyroclastic-flow deposits, at the south shore of Spirit Lake, and along the upper part of the North Fork Toutle River. These steam-blast explosions continued sporadically for weeks or months after the emplacement of pyroclastic flows, and at least one occurred a year later, on May 16, 1981.[8] Nach drei Jahrzehnten hat sich in den tiefer gelegenen und wasserreichen Gebieten eine Pioniervegetation überwiegend aus Rot-Erlen und mehreren Weidenarten gebildet. Die Bäume haben eine Höhe von mehreren Metern erreicht und das Aufkommen eines dichten Unterwuchses begünstigt. Trockenere Regionen sind von artenreichen Gras- und Staudenfluren überzogen, teilweise dominieren auch noch einjährige Blütenpflanzen. Die Hochlagen werden wegen der kurzen Vegetationsperiode erst langsam besiedelt. Purpur-Tannen sind meist noch keinen Meter hoch, kurzhalmige Gräser und Kräuter bilden Magerrasen. Mount St. Helens is an active volcano located in the United States' Pacific Northwest region. It is positioned about 96 miles (154 km) south of Seattle, Washington and 50 miles (80 km) northeast of Portland, Oregon

Der Aschenauswurf dauerte neun Stunden und konnte drei Tage später im Osten der USA registriert werden. Ein Teil der Asche gelangte in den Jetstream und umrundete so die Erde in zwei Wochen. Einige wenige Seen waren im Mai 1980 noch von Eis und Schnee bedeckt. In ihnen überlebte die aquatische Fauna vollständig. Fische, Amphibien, wasserbewohnende Insekten und andere Tiere begannen schon im Sommer, die unterhalb neu entstehenden Wasserläufe zu besiedeln. Am Meta Lake, rund 13,5 km vom Krater entfernt und vor der Druckwelle nur durch eine Eisschicht geschützt, fanden sich bereits 1985 wieder Biber ein. Ihre Dämme schufen Flachwasserbereiche, welche die Lebensbedingungen vieler Arten deutlich verbesserten. Vögel nutzten den See schnell als Nahrungsquelle. All of the post-1980 eruptions were quiet dome-building events, beginning with the December 27, 1980, to January 3, 1981, episode. By 1987, the third dome had grown to be more than 3,000 feet (910 m) wide and 800 feet (240 m) high.[52] This place in time: The Mount St. Helens story Recounts through reenactments, personal recollections, and documentary narration, the earth-changing event and aftermath of the May 18, 1980.

Most viewpoints on the monument's north, east, and south sides can be reached from Memorial Day until snow closes the roads, usually in late October. Trails are generally open from June through October, although some lower elevation trails can be hiked all year.

On the basis of activity in 1975-1976, scientists warned that Baker could be the site of the next eruption in the Cascade arc, a role usurped by Mount St. Helens five years later. Levels of the reservoirs in the Baker River valley, Baker Lake, and Lake Shannon were drawn down in preparation for inflows of lahars analogous to the Morovitz. Most of St. Helens' former north side became a rubble deposit 17 miles (27 km) long, averaging 150 feet (46 m) thick; the slide was thickest at one mile (1.6 km) below Spirit Lake and thinnest at its western margin.[8] The landslide temporarily displaced the waters of Spirit Lake to the ridge north of the lake, in a giant wave approximately 600 feet (180 m) high.[31] This in turn created a 295-foot (90 m) avalanche of debris consisting of the returning waters and thousands of uprooted trees and stumps. Some of these remained intact with roots, but most had been sheared off at the stump seconds earlier by the blast of super-heated volcanic gas and ash that had immediately followed and overtook the initial landslide. The debris was transported along with the water as it returned to its basin, raising the surface level of Spirit Lake by about 200 ft (61 m).[8]

Mount St. Helens Eruption: Facts & Information Live Scienc

Global Volcanism Program St

By 2005, life was starting to return to the barren landscape surrounding the mountain. However, as the steam eruptions starting in October 2004 illustrated, the danger of another catastrophic eruption is ever present. Visiting Mount St. Helens National Volcanic Monument is to simultaneously witness the result of catastrophic destruction and see the result of rebirth. Pyroclastic flow material passed over the moving avalanche and spread outward, devastating a fan-shaped area 23 miles across by 19 miles long (37 km × 31 km).[29] In total about 230 square miles (600 km2) of forest was knocked down,[29] and extreme heat killed trees miles beyond the blow-down zone. At its vent the lateral blast probably did not last longer than about 30 seconds, but the northward-radiating and expanding blast cloud continued for about another minute. A second, new crater and a blue flame were observed on March 29.[18][19] The flame was visibly emitted from both craters and was probably created by burning gases. Static electricity generated from ash clouds rolling down the volcano sent out lightning bolts that were up to two miles (3 km) long.[18] Ninety-three separate outbursts were reported on March 30,[18] and increasingly strong harmonic tremors were first detected on April 1, alarming geologists and prompting Governor Dixy Lee Ray to declare a state of emergency on April 3.[19] Governor Ray issued an executive order on April 30 creating a "red zone" around the volcano; anyone caught in this zone without a pass faced a $500 fine (equivalent to $1,600 today) or six months in jail.[20][21] This precluded many cabin owners from visiting their property.[22]

Mount St. Helens National Volcanic Monument Informationen . Lage und Größe Der 2.549 m hohe aktive Vulkan Mount St. Helens liegt im Süden des US-Bundesstaates Washington. Die Entfernung nach Seattle/Washington beträgt etwa 160 km, nach Portland/Oregon etwa 80 km Luftlinie. Das im Jahr 1982 gegründete Mount St. Helens National Volcanic. Seismic activity and gas emission steadily increased in early August, and on August 7 at 4:26 p.m., an ash cloud slowly expanded 8 miles (42,000 ft; 13 km) into the sky.[52] Small pyroclastic flows came through the northern breach and a weaker outpouring of ash rose from the crater. This continued until 10:32 p.m. when a second large blast sent ash high into the air, proceeding due north.[52] A second dacite dome filled this vent a few days later. Die vom Ausbruch wenig betroffenen Bereiche in Randlagen des Schutzgebietes sind für Besucher frei zugänglich, im Kern-Bereich und insbesondere den Regenerationsflächen herrscht Wegegebot. Einige Gebiete sind als Vorrangfläche für ökologische Forschung ausgewiesen und für Besucher unzugänglich. Für einen Aufstieg auf den Gipfel ist eine Anmeldung beim Forest Service erforderlich. Bergsteiger dürfen nur die Flanke und den Kraterrand betreten, das Innere des Kraters ist gesperrt.[22] Mount St. Helens National Volcanic Monument is a United States National Monument in southwest Washington State that was the site of a massive volcanic eruption on 18 May 1980. In 1982, the President and Congress created the 110,000-acre (445-km²) National Volcanic Monument, within the Gifford Pinchot National Forest, for research, recreation, and education.

Chemical compositionedit

Four decades after the eruption, floating log mats persist on Spirit Lake and nearby St. Helens Lake, changing position with the wind. The rest of the trees, especially those that were not completely detached from their roots, were turned upright by their own weight and became waterlogged, sinking into the muddy sediments at the bottom where they have become petrified in the anaerobic and mineral-rich waters. This provides insight into other sites with a similar fossil record.[32] At 8:32 a.m., a magnitude 5.1 earthquake centered directly below the north slope triggered that part of the volcano to slide,[29] approximately 7–20 seconds after the shock.[8] The landslide, the largest in recorded history, traveled at 110 to 155 miles per hour (177 to 249 km/h) and moved across Spirit Lake's west arm. Part of it hit a 1,150-foot-high (350 m) ridge about six miles (10 km) north.[8] Some of the slide spilled over the ridge, but most of it moved 13 miles (21 km) down the North Fork Toutle River, filling its valley up to 600 feet (180 m) deep with avalanche debris.[29] An area of about 24 square miles (62 km2) was covered, and the total volume of the deposit was about 0.7 cubic miles (2.9 km3).[8]

On May 18, 1980, Mount St. Helens erupted. The upper summit was blown off, everything within a radius of 8-miles was obliterated, and ash fell across 22,000 square miles The central area is mountainous, including five volcanos: Mount Baker, Glacier Peak, Mount Rainier, Mount St. Helens, and Mount Adams.

An eruption occurred on May 25, 1980, at 2:30 a.m. that sent an ash column nine miles (48,000 ft; 14 km) into the atmosphere.[44] The eruption was preceded by a sudden increase in earthquake activity and occurred during a rainstorm. Erratic wind from the storm carried ash from the eruption to the south and west, lightly dusting large parts of western Washington and Oregon. Pyroclastic flows exited the northern breach and covered avalanche debris, lahars and other pyroclastic flows deposited by the May 18 eruption.[44] Aus dem Jahr 1842 liegt ein detaillierter Bericht eines Pfarrers vor, der einen größeren Ausbruch von Champoeg, Oregon aus beobachtet hat. Vulkanische Asche fiel damals bis nach The Dalles, etwa 80 km südöstlich des Vulkans. Proben der Asche wurden im folgenden Jahr John Charles Frémont auf seiner Vermessungsexpedition am Columbia River übergeben. 1847 malte Paul Kane den Berg mit Rauchwolken, die aus einem Flankenvulkan etwa auf halber Höhe des Kegels austreten. Weitere kleinere Ausbrüche wurden aus den Jahren 1898, 1903 und 1921 gemeldet; da sie keine vulkanologischen Spuren hinterlassen haben, können sie nur geringe Intensität gehabt haben. The most popular tourist route into the Mount St. Helens area is via Washington state route 504. It can be reached at Castle Rock (exit #49) off Interstate 5 in Washington, about 2 hr 15 min north of Portland and two hours south of Seattle. If going north on the return route (Seattle/Tacoma), State Route 505 can be used as a short cut back to I-5 (turn right a few miles east of Toutle). This is not recommended for the initial trip up the mountain, as it bypasses the main visitor center near Castle Rock. If you are coming from Portland or anywhere south, Mount St Helens can be accessed from Woodland (exit 21 from I-5) along State Route (SR) 503. SR-503 becomes Forest Road (FR) 90 past Cougar and goes along the south side of Mount St Helens to (FR) 25, which goes north and south along the east side of Mt. St. Helens.

Mt The order of peaks climbed by Lage Wernstedt is speculated from photo number data provided by Harry Majors. * Based on research by Harry Majors (1973), confirmed at a different source by Roger Jung (2005), Lage Wernstedt made FAs of these peaks definitely in 1925, not 1926, a possibility surmised in CAG-3 Taking these two points of dispute into consideration, the direct death toll could be as low as 55 or as high as 60. When combined with the four indirect victims mentioned earlier, those numbers range from 59 to 64.

For example, when comparing the imaginary part of the refractive index k of stratospheric ash from 9.3 and 11.2 mi (15 and 18 km) from the volcano it has been discovered that they have similar values around 700 nm (around 0.009), while they differ significantly around 300 nm. Here, the 11.2 mi (18 km) sample (k was found to be around 0.009) was much more absorbent than the 9.3 mi (15 km) sample (k was found to be around 0.002).[39] Zwischen 1980 und 1986 dauerte die vulkanische Aktivität am St. Helens an.

Mount St. Helens is a remote destination for true wilderness recreation experiences in Washington's South Cascades. Located more than two hours from Portland, and accessible only by one single-lane U.S. Forest Service road, Mount St. Helens is sought out by hunters, anglers, equestrians and backpackers looking to escape into the Washington wilderness Camping near I-5 exits to Mount St. Helens along Route 504 is available at Seaquest State Park or south of Hwy 12 at Lewis & Clark State Park. There are also National Forest Service campsites south of Randle (NE of MSH access forest road 99) and along the Lewis River east of Cougar. In particular, the Markov Chain Monte Carlo method was applied with success to Mount St Helens (Anderson and Segall, 2011, 2013). As noticed by Segall (2013), a limitation of this approach is that it cannot account for epistemic uncertainties. Another limitation is potentially that it is not efficient to estimate model parameters evolving. Dome Peak is a high, massive, glaciated mountain in the Glacier Peak Wilderness of Washington's North Cascades. The remote location of Dome Peak, combined with its height, make it a less common destination for Cascade Range mountaineers. Dome Peak is at the southern end of the Ptarmigan Traverse mo Anfang Juni 1982, etwas mehr als zwei Jahre nach dem Ausbruch, brachte ein Abgeordneter im Repräsentantenhaus einen Gesetzentwurf ein, den Berg und sein Umfeld als Schutzgebiet vom Typ eines National Monuments auszuweisen. Da nahezu das gesamte vom Ausbruch betroffene Gebiet in Bundesbesitz war und bereits zum Gifford Pinchot National Forest, einem Nationalforst unter der Verwaltung des United States Forest Services, gehörte, gab es keine Widerstände und bereits am 26. August 1982 wurde das Schutzgebiet gewidmet.

Aus dem Jahr 1981 stammt ein Doku-Drama unter dem Namen St. Helens (deutsche Titel: Mount St. Helens – Der Killervulkan und St. Helens: Der tödliche Berg) mit Art Carney und David Huffman. Der Film orientiert sich am realen Geschehen rund um den Geologen David A. Johnston, der den Vulkan nach Beginn der aktiven Phase im März 1980 untersuchte und beim Ausbruch im Mai ums Leben kam. By the time this pyroclastic flow hit its first human victims, it was still as hot as 680 °F (360 °C) and filled with suffocating gas and flying debris.[33] Most of the 57 people known to have died in that day's eruption succumbed to asphyxiation, while several died from burns.[8] Lodge owner Harry R. Truman was buried under hundreds of feet of avalanche material. Volcanologist David A. Johnston was one of those killed, as was Reid Blackburn, a National Geographic photographer. Robert Landsburg, another photographer, was killed by the ash cloud. He was able to protect his film with his body, and the surviving photos provided geologists with valuable documentation of the historic eruption.[34] The last time London hosted the Olympics, the scarred city hadn't yet recovered from the ravages of World War II. In 1948, after a 12-year hiatus from the Games, the sporting world hadn't. Themen des Tages: ----- - Landtagswahlen im Saarland - Südkorea: Schwere Unruhen in Kwangju - West-Berlin: Einsturz der Kongresshalle im Tiergarten - Kanada: Unabhängigkeit der Provinz Quebec. Die abnehmende Aktivität des Vulkans führte dazu, dass im Krater seit 1986 entgegen dem weltweiten Trend ein neuer Gletscher entstand. Er wurde bei den kleinen Ausbrüchen 2004/05 nur deformiert, nicht vollständig abgeschmolzen und wächst seither wieder.[12] The hot, exploding material also broke apart and melted nearly all of the mountain's glaciers along with most of the overlying snow. As in many previous St. Helens' eruptions, this created huge lahars (volcanic mudflows) and muddy floods that affected three of the four stream drainage systems on the mountain,[35] and which started to move as early as 8:50 a.m.[31] Lahars travelled as fast as 90 miles per hour (140 km/h) while still high on the volcano but progressively slowed to about three miles per hour (4.8 km/h) on the flatter and wider parts of rivers.[8] Mudflows from the southern and eastern flanks had the consistency of wet concrete as they raced down Muddy River, Pine Creek and Smith Creek to their confluence at the Lewis River. Bridges were taken out at the mouth of Pine Creek and the head of Swift Reservoir, which rose 2.6 feet (0.79 m)[35] by noon to accommodate the nearly 18,000,000 cubic yards (14,000,000 m3) of additional water, mud and debris.[8]
