Seismic early warningUSGS awards $3.7 million to advance ShakeAlert early warning system
The U.S. Geological Survey awarded approximately $3.7 million to six universities to support transitioning the ShakeAlert earthquake early warning system into a production system. Additionally, the USGS has purchased about $1.5 million in new sensor equipment to expand and improve the ShakeAlert system and awarded about $0.25 million in supplements to earlier agreements to three universities. These efforts, as well as internal work that the USGS is conducting, are possible because of $8.2 million in funding to the USGS Earthquake Hazards Program for ShakeAlert approved by Congress earlier this year.
The U.S. Geological Survey awarded approximately $3.7 million to six universities to support transitioning the ShakeAlert earthquake early warning system into a production system. Those awards are being made through cooperative agreements with California Institute of Technology, Central Washington University, University of California, Berkeley, University of Oregon, University of Washington, and University of Nevada, Reno.

An earthquake early warning system can give people a precious few seconds to stop what they are doing and take protective actions before the severe shaking waves from an earthquake arrive. Under the new cooperative agreements, the USGS and its six university partners will collaborate to improve the ShakeAlert system’s sensor and telemetry infrastructure across the west coast of the United States. ShakeAlert is a new product of the USGS Advanced National Seismic System, a federation of national and regional earthquake monitoring networks throughout the country, including networks in southern California, northern California, and the Pacific Northwest.
New to these agreements is an emphasis on incorporation of real-time GPS observations into ShakeAlert. The USGS and its university partners will also further the development of scientific algorithms to rapidly detect potentially damaging earthquakes, more thoroughly test the warning system, and improve its performance. In addition, they will upgrade the networks and construct new seismic and geodetic sensors to improve the speed and reliability of the warnings. The ShakeAlert partners will also continue user training and education efforts, in collaboration with state and local partners, and add additional ShakeAlert test users. There are currently about seventy organizations that are test users, from sectors such as utilities, transportation, emergency management, state and city governments, and industry.
The ShakeAlert earthquake early warning system has been in development for ten years. In 2006, the USGS began funding multi-institutional, collaborative research to test warning algorithms on real-time seismic networks within the Advanced National Seismic System (ANSS). In California, this is a joint effort, where state legislation was passed in 2013 directing the California Office of Emergency Services to develop an early warning system in collaboration with the USGS and its partners. The State of California has recently committed $10 million to CalOES to enhance the statewide build-out of the California Earthquake Early Warning System. The State of Oregon also recently contributed about $1million of funding to enhance the system in Oregon.
The USGS estimates it will cost $38.3 million in capital investment to complete the ShakeAlert system on the West Coast to the point of issuing public alerts, and $16.1 million each year to operate and maintain it. This is in addition to current support for seismic and geodetic networks.
At a White House Earthquake Resilience Summit in February, it was announced that the ShakeAlert system had developed to a stage that was ready to support limited test uses in some areas of California. This next-generation production prototype allows selected users to develop and deploy pilot implementations that take protective actions based on the USGS ShakeAlert warnings in areas with sufficient station coverage.
