Aerial view of Spirit Lake (center) looking north from above the crater of Mount St. Helens. The lake's outlet to the west (left) was blocked by the 1980 landslide, which required a new engineered outlet to maintain the lake at a safe level. A tunnel was drilled through a bedrock ridge on west side of lake in 1984-1985. Glacier covered Mount Rainier in distance.

Between August 19-22, 2017, 140 seismometers were deployed around Mount St. Helens. Instruments were placed on top of the 2004-2008 lava dome, the 1980-86 lava dome, the 1980 crater floor, and around the volcanic cone.

Graphic shows an east to west cut-away of Mount St. Helens with an interpreted model of seismic wave speeds under the volcano and earthquakes from 2008-2016. The colors of the model represent changes in seismic p-wave velocities from tomographic studies (Waite and Moran, 2009; doi:10.1016/j.jvolgeores.2009.02.009).

Land Remote Sensing Image of Mount St. Helens on May 22, 1983. The volcanic blast on May 18, 1980, devastated more than 150 square miles of forest within a few minutes. In this Landsat false-color images, forest appears as bright red interspersed with patches of logging. Snow appears white, and ash is gray.
