Very large earthquakes that occur closer to the Northern California coast could cause damaging levels of ground shaking here too.Much of the north-eastern part of the state is actively stretching apart, creating numerous faults, all capable of producing earthquakes.The Modoc Plateau has both active volcanoes and faults. In addition to volcanoes, this is also earthquake country. The Trinity Mountains, Modoc Plateau, Shasta and Lassen peaks were created by geologic forces that are still shaping the landscape.*The 75% probability of one or more magnitude 7.0 earthquakes striking Southern California is based on a 30-year period, beginning in 2014.Ĭounties: Butte, Glenn, Lassen, Modoc, Plumas, Shasta, Sierra, Siskiyou, Tehama, Trinity See why it is worth it to earthquake retrofit a home in San Diego.The Elsinore and San Jacinto faults cut through East County and can also generate moderately-sized but potentially damaging earthquakes.Geologists say this is the biggest earthquake threat to San Diego, capable of earthquakes of magnitude 6.9. The Rose Canyon fault runs along the coast and beneath downtown San Diego. The San Andreas fault is the longest fault in California and can cause powerful earthquakes-as big as magnitude 8-that can still generate strong shaking levels in San Diego.Many of the mountains, and some of the valleys, in Southern California were formed by the San Andreas fault system-the tectonic boundary between the Pacific and North American tectonic plates-which runs to the east of San Diego County from the Gulf of California up through the Salton Sea and into the Los Angeles region. Like all of California, San Diego is earthquake country.What is the Earthquake Risk in San Diego? *The 76% probability of one or more magnitude 7.0 earthquakes striking Northern California is based on a 30-year period, beginning in 2014. See the USGS interactive fault map to learn more about faults in this area Landslides are possible on steep hillsides. Houses on liquefied soil may settle or even move laterally on gentle slopes.
