Volcano seminars at WSU
Washington State University Vancouver will present a series of Monday evening seminars and public events where scientists will discuss what has been learned since the May 18, 1980, eruption of Mount St. Helens.
The events have been planned to commemorate the 25th anniversary of the volcano's 1980 blast, which flattened more than 150 square miles of forest, killed 57 people and sent a cloud of ash around the earth.
Over the last 25 years, scientists say, Mount St. Helens has proved to be a remarkable laboratory for the study of earth processes and their influence on ecosystems surrounding the volcano.
All seminars -- March 21, April 18 and April 25 -- will begin at 7 p.m. in the Student Services Building, Room 110, at the Vancouver campus. The seminars are free and open to the public.
The following subjects are scheduled for discussion:
March 21 -- "Mount St. Helens Seismicity Then and Now: What the last 25 years has taught us about how the volcano works" will be presented by Seth Moran, research seismologist for the U. S. Geological Survey, Cascades Volcano Observatory.
Moran will compare the earthquake activity that occurred prior to eruptions of 1980, 2004 and 2005. He will also examine what might have been happening during the quiet period, between 1987 and 2003.
n April 18 -- "Out of the Ash: Survival and Recolonization in a Volcanic Landscape," the first of two talks, will be presented by Peter Frenzen, head scientist for the Mount St. Helens National Volcanic Monument.
Charlie Crisafulli, research ecologist for the Forest Service Pacific Northwest Research Station, will give the second talk, titled "Mount St. Helens: A Story of Survival and Revival of Life".
April 25 -- "Something Extraordinary is Happening in the Crater at Mount St. Helens: Lessons from the 1980-1986 and 2004-2005 Dome-Building Eruptions" will be presented by Dan Dzurisin, geologist for the U. S.Geological Survey, Cascades Volcano Observatory, Vancouver.
