USGS Cascades Volcano scientists listen to and watch volcanoes using a variety of equipment. Seismometers detect earthquakes, GPS receivers detect ground motion, "sniffers" detect volcanic gas, and staff innovate new equipment to solve unique activity detection needs.
A geophysicist from the Cascades Volcano Observatory notes the location of a newly buried seismometer at station PARA, on Mount Rainier.
The David A. Johnston Cascades Volcano Observatory (CVO) is a volcano observatory in the US that monitors volcanoes in the northern Cascade Range. It was established in the summer of 1980, after the eruption of Mount St. Helens.
