The May 18, 1980, eruption of Mount St. Helens was historic and fundamentally changed how we see volcanoes. For those who lost family and friends, homes, and their livelihoods, it was an unimaginable tragedy. For others around the world, the eruption was an exciting curiosity, an experience they could share with their kids and grandkids.

Title: Mount St. Helens Revisited: Lives Changed, Lessons Learned, and Legacies of the 1980 Eruptions

By Carolyn Driedger, USGS Hydrologist & Outreach Specialist

Jon Major, scientist-in-charge of the USGS Cascades Volcano Observatory, provides an overview of the major volcano hazards in the Cascades, the function and responsibilities of the Cascades Volcano Observatory, and a brief synopsis of what's been going on at Mount Baker, Glacier Peak, Mount Rainier, Mount Adams, Mount St.

The 1980 eruption of Mount St. Helens was monumental in so many different ways. It had a huge impact on the geography of southwestern Washington, ash affected many people, lives were lost, and lessons were learned. The eruption also led to the creation of the USGS Cascades Volcano Observatory in Vancouver, Washington.

The good news is that volcanoes usually change behavior before they erupt, in ways that are detectable by monitoring instruments.

Throughout most of human existence, we haven't known much about how volcanoes work. Because of their immense power, they have terrified and fascinated us, and remain places of great spiritual importance for many people. The lack of knowledge about volcanoes has sometimes resulted in tragic and deadly disasters.

How did the May 18, 1980 eruption of Mount St. Helens change peoples’ lives? Carolyn Driedger talks about events that led up to the 1980 eruption and influenced scientists’ response to it, as well as what happened on May 18, and how the eruption changed people's lives and professions.

What stories do rocks tell? What techniques do scientists use to study volcanoes? Dr. Heather Wright talks about the May 18, 1980 eruption of Mount St. Helens, provides an overview of volcanoes and how they erupt, and shows why scientists continue to monitor this active volcano, in this presentation to the Sno-Isle Libraries’ 2021 Whidbey Reads program.

During Aug. 4-8, 2019, U.S. Geological Survey women scientists, university researchers and Mount St. Helens Institute staff led 25 middle-school girls from Washington and Oregon in the fifth annual “GeoGirls” outdoor volcano science program at Mount St. Helens, Washington.
 

On September 25, 2018, a team of three scientists based at the USGS–Cascades Volcano Observatory conducted the first-ever USGS-led Unmanned Aircraft Systems (UAS) campaign at Mount St. Helens. The UAS survey was conducted with the permission and coordination of the U.S. Forest Service Mount St. Helens National Volcanic Monument.

Twenty middle-school girls from Washington and Oregon participated in the 2016 “GeoGirls” outdoor volcano science program at Mount St. Helens, jointly organized by the U.S. Geological Survey and the Mount St. Helens Institute. 

Volcano gas geochemistry has been around for a long time. Scientists can make gas measurements using very large, very expensive Correlation Spectrometers or collect samples in the field and bring them back for analysis in the lab. But it’s possible we’re missing out on a lot of information because our monitoring capabilities don’t include continuous observation.

The video shows time-lapse changes in the lava dome and Crater Glacier from 2004-2012. The images were created from 1:12,000 scale vertical aerial photographs combined with ground control points from campaign GPS and targets. Photogrammetry software was used to collect a 3-D point cloud and combined to make a digital elevation model (DEM).

USGS scientists recount their experiences before, during and after the May 18, 1980 eruption of Mount St. Helens. Loss of their colleague David A. Johnston and 56 others in the eruption cast a pall over one of the most dramatic geologic moments in American history.

The May 18, 1980 eruption of Mount St. Helens triggered a growth in volcano science and volcano monitoring. Five USGS volcano observatories have been established since the eruption. With new technologies and improved awareness of volcanic hazards USGS scientists are helping save lives and property across the planet.

The rapid onset of unrest at Mount St. Helens on September 23, 2004 initiated an uninterrupted lava-dome-building eruption that continued until 2008. The initial phase produced rapid growth of a lava dome as magma pushed upward.

Mount St. Helens reawakened in late September 2004. Small magnitude earthquakes beneath the 1980-1986 lava dome increased in frequency and size, and a growing welt formed on the southeast margin of the previous lava dome and nearby portions of Crater Glacier.
