USGS scientists Wes Thelen and Alex Iezzi talk about what they are doing to learn more about recent earthquake activity at Mount Adams (November 20, 2024)
In September, the USGS Cascades Volcano Observatory (CVO) and Pacific Northwest Seismic Network (PNSN) located six earthquakes at Mount Adams ranging in magnitudes from 0.9 to 2.0. While six doesn’t sound like much, earthquakes at this volcano are typically located at a rate of about one earthquake every two to three years. With permission, CVO scientists rapidly installed three temporary seismic stations closer to the volcano to enlarge the permanent monitoring network. The temporary stations included a seismometer buried in the ground, a plastic case that contained batteries charged by a solar panel, and a cell antenna so data could
