This page was designed to be a user friendly, graphical interface to selected Pacific Northwest seismographs. The actual real-time seismograph data, which the colored dots on the above map connect to, is acquired and made available to the internet by the U.S. Geological Survey, Earthquake Hazards Program and the Pacific Northwest Seismograph Network. PNSN is based in the Department of Earth and Space Sciences at the University of Washington, and is jointly operated by the PNSN Operational Partners.

For a more comprehensive, non-graphical listing of near real-time seismograph displays throughout the northwest, visit PNSN Regional Stations, PNSN Volcano Stations and PNSN Urban Strong Motion Stations.  For a near real-time listing of all earthquake activity around the world, go to Recent Worldwide Earthquake Activity courtesy of the U. S. Geological Survey, or the Seismic Monitor map courtesy of the Incorporated Research Institutions for Seismology -- IRIS.
