Seismic signatures of the most common events that cause the ground ...

Detailed Description

The overall shape of each seismic signature is easy to see by comparing the amplitude (height of waveform), frequency (width from peak to peak within waveform), and duration (length of waveform) of each signature. The "tic" marks on each signature represent 1 minute in time. Earthquake activity at Mount Rainier volcano is monitored by scientists of the Pacific Northwest Seismic Network, University of Washington, with support from the USGS.
