S. Geological Survey National Seismic Hazard Model in California introduces a new earthquake rate model and new ground motion models (GMMs) that give rise to numerous changes to seismic hazard throughout the state. The updated earthquake rate model is the third version of the Uniform California Earthquake Rupture Forecast (UCERF3), wherein the rates of all ruptures are determined via a self\u2010consistent inverse methodology. This approach accommodates multifault ruptures and reduces the overprediction of moderate earthquake rates exhibited by the previous model (UCERF2). UCERF3\u00a0introduces new faults, changes to slip or moment rates on existing faults, and adaptively smoothed gridded seismicity source models, all of which contribute to significant changes in hazard. New GMMs increase ground motion near large strike\u2010slip faults and reduce hazard over dip\u2010slip faults. The addition of very large strike\u2010slip ruptures and decreased reverse fault rupture rates in UCERF3 further enhances these effects.<\/jats:p>","DOI":"10.1193\/110314eqs176m","type":"journal-article","created":{"date-parts":[[2015,10,16]],"date-time":"2015-10-16T15:11:37Z","timestamp":1445008297000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["2014 Update to the National Seismic Hazard Model in California"],"prefix":"10.1002","volume":"31","author":[{"given":"Peter M.","family":"Powers","sequence":"first","affiliation":[{"name":"U.S. Geological Survey PO Box 25046, MS 966 Denver CO 80225"}]},{"given":"Edward H.","family":"Field","sequence":"additional","affiliation":[{"name":"U.S. Geological Survey PO Box 25046, MS 966 Denver CO 80225"}]}],"member":"311","published-online":{"date-parts":[[2019,12,8]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1193\/072113EQS209M"},{"key":"e_1_2_8_3_1","unstructured":"Building Seismic Safety Council (BSSC)2009NEHRP Recommended Seismic Provisions for New Building and Other StructuresFederal Emergency Management Agency Publication Number P\u2010750 available athttp:\/\/www.fema.gov\/media\u2010library\/assets\/documents\/18152\/(last accessed January 2014)"},{"key":"e_1_2_8_4_1","unstructured":"DawsonT.
