Seismological Research Letters 86 2A 309–326 2015SeiRL..86..309B The 2014 South Napa earthquake occurred in the northern San Francisco Bay Area on August 24 at 03:20:44 Pacific Daylight Time 10:20:44 UTC. At 6.0 on the moment magnitude scale and with a maximum Mercalli intensity of VIII (Severe), the event was the largest in the San Francisco Bay Area since the 1989 Loma Prieta earthquake. The epicenter of the earthquake was located to the south of Napa and to the northwest of American Canyon on the West Napa Fault. http://m.sfgate.com/bayarea/article/Boats-grapes-and-Poseidon-at-Napa-quake-s-5714272.php Boats, grapes and Poseidon at Napa quake's epicenter Fimrite Peter August 27, 2014 San Francisco Chronicle September 2, 2017 Total damage in the southern Napa Valley and Vallejo areas was in the range of $362 million to $1 billion, with one person killed and 200 injured. Other aspects of the event included an experimental earthquake warning system that alerted seismologists several seconds before the damaging shear waves arrived, temporary changes in springs and wells, and the potential for postseismic fault creep. Tectonic setting California earthquake forecast Strike-slip tectonics The San Andreas Fault System is an active plate boundary comprising right-lateral strike-slip faults that runs nearly the length of California. This network of faults trends north-northwest in the area of the West Napa Fault, where it is 80 km flip wide from west to east. The West Napa Fault transfers slip between a group of related faults (including the Concord Fault and the Calaveras Fault) called the Contra Costa Shear Zone, which was assigned a maximum slip rate of 1mm/yr in the third Uniform California Earthquake Rupture Forecast. The authors of a separate study that focused on Global Positioning System data gave an estimated slip rate of 4±3mm/yr for the West Napa Fault.The Mw 6.0 24 August 2014 South Napa Earthquake https://seismo.berkeley.edu/~rallen/pub/2015brocher/BrocherEtAl-SRL-2015.pdf T.

Seismic Warning Systems, Inc., a private earthquake warning company based in Scotts Valley, California, had installed on-site warning systems at five fire stations in Vallejo in 2002 and 2003.Wurman Gilead Price Michael J. Earthquake Warning Performance in Vallejo for the South Napa Quake 2014 AGU Fall Meeting 2014 S33F–4937 San Francisco, CA These systems commanded the bay doors to open at these fire stations between 1.7 and 2.4 seconds before the S waves arrived at each fire station. Earthquake warning systems could potentially give people time to take cover in the event of a quake, preventing injuries caused by falling debris, automatically stopping trains or shutting off gas lines. The system being developed at the Berkeley Seismological Laboratory (called ShakeAlert) in conjunction with the United States Geological Survey, the California Institute of Technology and the University of Washington, will eventually cover the entire West Coast. The system would cost $80 million in funding to run for five years in California, or $120 million for the whole West Coast. https://www.wsj.com/articles/early-warning-system-in-testing-sounded-alarm-before-quake-1408999597 Expanding Earthquake Warning System May Help the Public Elinson Zusha August 25, 2014 The Wall Street Journal August 26, 2014 In December 2014, United States Congress approved a $5 million allocation as part of the Consolidated Appropriations Act, 2014 in order to expand funding for development of the system.http://www.latimes.com/local/california/la-me-quake-early-warning-20141215-story.html California receives U.S. funding for earthquake early-warning system- LA Times December 14, 2014 Rong-Gong Lin II December 31, 2014 See also San Francisco Bay Area California List of earthquakes in 2014 List of earthquakes in California List of earthquakes in the United States References https://earthquake.usgs.gov/earthquakes/eventpage/nc72282711#summary M6.0 – 6 km NW of American Canyon, California United States Geological Survey Further reading Injuries and Traumatic Psychological Exposures Associated with the South Napa Earthquake – California, 2014 Attfield K.
