TOPIC: California’s Earthquake Early Warning System – Where Is It?

SPEAKER: John Parrish, Ph. D, PG, State Geologist, California Geological Survey

Event Registration Link: https://conta.cc/2GQsNVo

Proposals for an Earthquake Early Warning System (EEW) for California have been made since the 1870’s, following the Great Hayward Earthquake of 1868 in the San Francisco Bay area.  Most recently (about the last 10 years), the U. S. Geological Survey has been developing an EEW system for California and the entire U. S. Pacific Coast.  Joining in the project are the seismological laboratories at the California Institute of Technology and U. C. Berkeley.  The California Geological Survey (CGS) is involved as a member of the California Integrated Seismic Network and because of its existing large seismic network throughout the State.  By Legislative Statute, the EEW program in California is being overseen by the Governor’s Office of Emergency Services.

After Alaska, California is the most seismically active state in the nation – and, unlike Alaska, California has 40 million inhabitants and operates the World’s sixth largest economy.  All of this has been developed on the most earthquake prone parts of the State – thus the need for an EEW system.  Funding for the development of the EEW system has been sketchy at best, and no funding for the continued operations of the system once installed has been approved.  It is the intention of the system developers to have an operating system for portions of southern California (greater Los Angeles area) in place by the end of 2018.
