SAFRR - Science Application for Risk Reduction

Earthquake Early Warning (EEW)


Late in 2007, SAFRR staff participated in discussion with Caltech, U.C. Berkeley, and the USGS to create an Earthquake Early Warning System. After the results of the ShakeOut Scenario's success in 2008, Earthquake Early Warning has gained momentum as potentially serving to mitigate injury, property damage, and the loss of life (if implemented before the next big earthquake).

SAFRR continues to support this effort by assisting project leads in connecting with early test users of the ShakeAlert interface, introducing the project to future users, and building a coalition of supporters.

The EEW project continues to make strides and gain traction, with the latest information being updated at

In October 2015, the USGS, City of Los Angeles mayor’s office, and Los Angeles Unified School District (LAUSD) began a collaborative pilot project to install and test the ShakeAlert Earthquake Early Warning system in classrooms at the Eagle Rock High School. The project will provide both a science and technology educational opportunity for the school as well as a means to inform ShakeAlert system improvement based on feedback regarding functioning, understanding, and potential uses of the system in an educational setting. A press conference was held on October 23rd, 2015 at 12:30 pm at Eagle Rock High School, where speakers included the LA Mayor, district officials, school officials, and SAFRR's Dr. Lucy Jones.

More information on the ShakeAlert system can also be found in the USGS ShakeAlert Fact Sheet.
