away. At the same time, Ty and Mariana Kearney were photographing it from the west side, as well as Keith and Dorothy Stoffel from the air. Arriving also at the moment of eruption was KOMO News photographer Dave Crockett. As the ash cloud loomed overhead and continued to spread out, a lahar coming down the South Fork Toutle River blocked his path of escape. He then got out of the car and began filming the eruption's ash column as well as the lightning and the lahars. As the cloud began darkening the sky he began a trek up a logging road and turned the camera on once again, this time narrating his video in what was recorded as a "death march." The video, of which 11 minutes is recorded in total darkness, was played out on newscasts worldwide.

US-GDP index for stuff like the cost of a natural disaster. I'm not 100% sure I did the "refined estimate" correctly. The problem is that the estimate itself is sourced, but the calculation itself was not. It was just a link to some dodgy website. The source doesn't explicitly say what year its estimate is from. The paper was written in 1990, but it's talking about financial estimates of a disaster that happened in 1980.

map used here (with yellow across the Northwestern quarter of the U.S.) as being not of "traces" of ash "detected," but "measurable depth," which I would take to mean only includes where there was a continuous layer of ash, unlike where I lived where the ash I found was only in tiny clumps. (I suspect the clumping was due to dewfall, however, and on other surfaces would have been more likely to be continuous.)

subsequent eruptions of a smaller scale, which carried the ash there, Despite this map showing the fallout for the May 18th eruption, I still somewhat question its validity as well, I know several people from outside of the highlighted areas who also found a film of ash within a few days of the major eruptive event. 🌀
2916:
OK, I've done some research. Firstly, there is a map online published in this instance by the Denver Post, but probably published around the nation, showing how far the ash reached by each day after the blast, which shows the ash reaching the Atlantic in three days. Secondly, other sources cite the

I question it as well. I was in grad school in Indiana at the time and was studying outdoors; I kept having to wipe grit from the page of my text, and on the third page I'd had to wipe clean it dawned on me what it had to be. Friends in both Gary at the north end of the state also reported the same

The article states "The eruption was the most significant to occur in the contiguous 48 U.S. states since the much smaller 1915 eruption of Lassen Peak in California". But in that case, it was the most significant for a longer time. Indeed, as I cannot find evidence of larger eruptions, I am changing

At the moment of eruption, Gary Rosenquist was alerted to the volcano by a few members of his camping party and began firing off the first of a 24-frame sequence that clearly illustrated the landslide and beginning moments of the lateral blast and simultaneously doing so was Keith Ronnholm a few feet

The May 18, 1980 eruption of Mount St. Helens was preceded by a series of volcanic explosions and pyroclastic flows that began on March 27, 1980, in Skamania County, Washington, United States. A series of phreatic blasts occurred from the summit and escalated until a major explosive eruption took

as well as University of Washington graduate student Keith Ronnholm had been waiting. In the air directly above the volcano, geologists Keith and Dorothy Stoffel had chartered a Cessna aircraft from Yakima to do some photographic documentation of the summit bulge. To the west near the South Fork

Can some clearer definition of the ashfall zone be given? At one place, it states that detectable levels of ash covered 22,000 square miles, a fraction of the size of Washington state. The map shows ashfall half-way across the Northern United States, maybe half a million square miles. And I

I believe the US map is specifically for the May 18th eruption and measured fallout from that specific eruption event, which would have missed Portland due to the prevailing winds at that time. I do know that Portland experienced ash fallout too, but it was from prior eruptions and also from

state that there were 12 injuries amongst survivors in the "damaged areas", while outside the "tree destruction zone" there were two deaths but all the survivors "escaped without serious injury". The USGS "Impact and aftermath" does not record any impacts outside the vicinity of the volcano.

The eruption of Mount St. Helens on May 18, 1980 was also one of the most well documented volcanic eruptions in recorded history. It is also one of very few major volcanic eruptions ever to be recorded on film at the moment of eruption. Early that morning at around 3 a.m. local time,

Maybe this could be added to the chapter with remark of divergent data concerning loss of height. I do not attend to modify this myself, as being neither familiar with this science, nor being a native speaker. Kind greetings to all! Stamnariophilus 08:08, 5 October 2018 (UTC)

i found the fact that Mt. St. Helens' summit had been reduced by about 1280 feet (390 m). When comparing the volcanoe's pre-eruptive height of 9677' (2949.5 m) with the post-erutive one of 8363' (2549 m), the resulting difference is 1314' (400.5 m). Data are taken from

The date of the main event is buried beneath large paragraphs poorly broken, and on a cursory examination it appears that the event took place in March, which of course is not the case. The lede needs to be rewritten to highlight the actual date.

I agree we should stick to the map we have unless another one is found. I do however think it does have its imperfections, but it comes from a reliable source, so there is no real need to change anything as of now.

Cousins in Nebraska also experienced ash falling, in Kearney and Grand Island; one cousin managed to collect a pint jar full by carefully washing the roof of the house.

I question the validity of the US map of ash distribution. I have several friends from Portland, OR who dealt with the ash fallout, but the map does not include them.
