GPS Earthquake Analysis Network

Location of the more than 500 real-time GPS monitoring stations in the western United States that make up the Real-Time Earthquake Analysis for Disaster Mitigation Network. The networks stations are overlain on a U.S. Geological Survey seismic hazard map showing areas forecast to have a 10-percent probability of exceeding a certain level of ground shaking within the next 50 years. (Areas in shades of red have the strongest shaking, while areas in green shades have the weakest shaking.)
