Pacific Northwest Seismograph Network

University of Washington Geophysics Program
Information on Pacific Northwest earthquake activity and hazards is provided by the Pacific Northwest Seismograph Network (PNSN) which operates seismograph stations and locates earthquakes in Washington and Oregon. The PNSN is operated jointly by the University of Washington, the University of Oregon, and Oregon State University, and is funded by the U. S. Geological Survey, the Department of Energy, and the State of Washington. The PNSN is based at the Geophysics Program of the University of Washington in Seattle, and is a member of the Council of the National Seismic Systems (CNSS), a group of regional network operators who cooperate to locate and catalog earthquakes throughout the United States. -- Information courtesy University of Washington's Geophysics Program, 1998

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 Mount Adams, Mount Rainier, Mount St. Helens, Mount Hood, Mount Baker, Three Sisters, and Crater Lake. -- Information courtesy University of Washington's Geophysics Program, 2001
