ShakeAlert Earthquake Early Warning System
Pullman Police Department
PULLMAN –According to the U.S. Geological Survey, the Pacific Northwest is susceptible to three main types of earthquakes, as well as episodic tremor and slip events. ShakeAlert, an earthquake early warning system for the West Coast, goes live on May 4, 2021. The system is capable of rapid detection of earthquake activity and provides mobile alerts to those in the impact area.
The May 4 launch of the system is only the beginning, with additional seismometers to be added to the network through 2025. The sensor network is currently ~65% complete for Washington State, with work ongoing to enhance system capabilities and improve warning delivery rates.
While the system is not intended to replace emergency planning by individuals and families, ShakeAlert has the potential to save lives and reduce injuries, providing precious seconds for people to prepare and protect themselves. ShakeAlert is operated by the U.S. Geological Survey and the Pacific Northwest Seismic Network.
Washington residents should ensure that Wireless Emergency Alerts are turned on for mobile devices.
