Using the statistical method of Evans et al. (in prep. 2019) the location and focal mechanism of this earthquake suggest the above association with modeled faults in the <a href=\"https:\/\/www.scec.org\/research\/cfm\" target=\"_blank\" rel=\"noopener noreferrer\">Community Fault Model (CFM)<\/a> provided by the Southern California Earthquake Center (SCEC) and Harvard University. Note that the CFM fault association may be different from the nearby faults list. Differences may arise due to different fault databases, and because the CFM fault association uses the hypocenter with relation to subsurface 3-dimensional fault orientation models, while the nearby faults list utilizes mapped surface traces as they relate to the epicenter.<\/p>\n<p>CFM Fault: SCEC CFM 5.0 Fault name and closest segment if available; The CFM is maintained by Harvard University, Dept of Earth &#038; Planetary Sciences.<\/p>\n<p>Probability: The probability in percent the earthquake is associated with this fault.<\/p>\n<p>SCSN: Caltech\/USGS Southern California Seismic Network<\/p>\n<p><span>&#42;&#42;<\/span>U.S. Geological Survey and California Geological Survey, 2006, Quaternary fault and fold database for the United States, accessed 2015, from USGS web site: <a href=\"https:\/\/earthquake.usgs.gov\/hazards\/qfaults\/\">https:\/\/earthquake.usgs.gov\/hazards\/qfaults\/<\/a><\/p>\n<p><\/p>\n<p>This information is subject to change as more up-to-date data become available.<\/p>\n<p><\/small><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Event 10 Aug 2020 08:56:15 PDT, (33.247, -115.682), depth 10.8km. 12km SSE of Bombay Beach, California Aftershocks As of 10 Aug 2020, 10:16AM PDT, there have been 29 aftershocks recorded.
