The Seismology Lab also maintains an audio library system with information about current earthquake activity, earthquake prediction and an overview of Pacific Northwest earthquake hazards. Voice mail is available to request more information or leave questions for Seismology Lab staff. The audio library number is: (206) 543-7010. To request materials for classroom use, call (206) 685-8180.
The Department of Earth and Space Sciences is home to the Pacific Northwest Seismograph Network (PNSN), an array of about 250 seismograph stations located throughout Washington and Oregon. The data from these instruments is telemetered in real time to the Seismology Lab at the University of Washington, where it is analyzed and all earthquakes are located and measured. The PNSN locates about three thousand events each year and automatically notifies emergency managers of all events large enough to be felt. The network also closely monitors seismicity below the Cascade volcanoes, serving as an early warning system to detect changes which could lead to eruptive activity.
