Earthquakes commonly provide the earliest warning of volcanic unrest, and earthquake swarms immediately precede most volcanic eruptions. Information on Pacific Northwest earthquake activity and hazards is provided by the Pacific Northwest Seismic 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. -- Wright and Pierson, 1992; and the University of Washington's Geophysics Program

- -- showing relationship between time and depth of earthquakes (quality BB or better) beneath Mount Rainier. "0" depth corresponds to 3 kilometers (about 2 miles) below the summit of Mount Rainier, which is the average station elevation of recording seismographs near Rainier. -- Modified from University of Washington's Geophysics Program
