In addition to locating regional earthquakes, the Pacific Northwest Seismograph Network (PNSN), in cooperation with the Cascades Volcano Observatory, is also responsible for monitoring seismic activity at volcanoes in the Pacific Northwest. The PNSN currently operates seismometers on or near several other Cascade volcanoes. Click a volcano name on the above menu to go directly to its' PNSN webpage.

1. In September of 1998, two new seismograph stations (SLF, Sugar Loaf; and WRW, Wenatchee Ridge) were installed near Glacier Peak to better monitor seismicity. These stations are located south of Lake Chelan. Station WRW is close enough to appear on the map of seismicity.
2. In September of 2001, a new seismograph station, GPW, was installed on Glacier Peak volcano. Dr. Jeff Johnson, a former UW graduate student, helped with installation, and took photographs of the installation procedure and station location. Visitors can find his installation page here:
