Summary
Abstract: Earthquake location maps for the NE Pacific have been accumulated
since August 29, 1991. The source location fixes are based on bearing
and arrival time information at 3 to 11 SOSUS hydrophone sites. Source
levels are estimated from received amplitudes and a simple
transmission loss model.

Animations of selected seismic swarms from volcanic activity recorded
along the Juan de Fuca and Gorda Ridges are also available. In
addition, a .wav file is available for download to listen to
earthquake activity. These volcanic seismic swarms are characterized
by downrift migrations of epicenters through time. Note that you will
need an MPEG viewer for your Web client.
