Earthquake Early Detection System in California Only Halfway Complete After 11 Years of Research and Millions in Funding

California, Oregon, and Washington have been working on an early warning detection system for earthquakes since 2006, but the NBC Bay Area Investigative Unit has learned the system is still only about 50 percent complete.

For accuracy and reliability, the system relies on monitoring stations setup along the west coast. To date, about 750 stations have been constructed – roughly 250 of those are in the Bay Area. Scientists, however, say 1,675 stations are needed to give people adequate warning in the event of an earthquake. The early detection system, known as Shake Alert, remains in a testing phase but can provide between a few seconds to upwards of a minute of notice.

Roughly $26.4 million have been allocated to the program, however, $38.3 million is needed to completely build out the system and another $16 million is required annually to maintain Shake Alert, according to the U.S. Geological Survey,

The federal agency, which is leading the research effort, tells NBC Bay Area the U.S. has fallen behind countries like Japan, Chile, and Mexico, where earthquake detection systems are already in place.

Scientists with the U.S. Geological Survey believe there is a 98 percent chance a 6.0 magnitude earthquake or larger will rattle the Bay Area sometime between now and the next 30 years.

In California, there is still no expected release date on when Shake Alert will be available to the public. The hope is the technology will eventually be tied into smart phones, vehicles, hospitals, and more. While the system remains in the testing phase, BART, PG&E and LA Metro already use the program to quickly shut off services in the event of an earthquake.

California is expected to begin using the technology in schools by 2018.
