Mount St. Helens eruption highlights: September 2004 - May 2005
Compilation video of significant events from the dome-building eruption at Mount St. Helens, from October 1, 2004 to March 15, 2005, including steam and ash eruptions, growth of lava spines, helicopter deployment of monitoring equipment, collection of lava samples, and FLIR thermal imaging of rock collapse on lava dome.

Muir and Riggs Glaciers, Muir Inlet, Alaska
Glaciers
As this picture of Muir and Riggs Glaceris in Alaska shows, glaciers are really rivers, but rivers of solid ice instead of liquid water. Just because they are solid does not mean they don't move, though. Glaciers do flow downhill, just very, very slowly.

Physiographic Cascadia
Cascadia encompasses the volcanoes of the Cascade Range and the subduction zone that feeds them. The region is home to nearly 10 million people. Where and how these people live, work, and play are influenced by the shape, or physiography, of Cascadia. This map is a tool for visualizing and interpreting the physiography of Cascadia.

Tsunami Hazards in the Santa Barbara Channel
Large-scale poster describing USGS work.
The USGS, in cooperation with Moss Landing Marine Laboratory, mapped the slopes of the Santa Barbara Channel using sonar. We combined this with deep sea drilling records and seismic records to make these maps.
