The probability of a serious earthquake on various faults has been estimated in the 2008 Uniform California Earthquake Rupture Forecast. According to the United States Geological Survey, Southern California experiences nearly 10,000 earthquakes every year. [3] Details on specific faults can be found in the USGS Quaternary Fault and Fold Database.
The 2015 Uniform California Earthquake Rupture Forecast, Version 3, or UCERF3, is the latest official earthquake rupture forecast (ERF) for the state of California, superseding UCERF2. It provides authoritative estimates of the likelihood and severity of potentially damaging earthquake ruptures in the long- and near-term.
Stretching for 250 kilometers (160 mi), it is the second-longest fault in California, and one of the most prominent geological features in the southern part of the state. It marks the northern boundary of the area known as the Mojave Block, as well as the southern ends of the Sierra Nevada and the valleys of the westernmost Basin and Range ...
Northern California was rocked by a 7.0 magnitude earthquake late Thursday morning.. After the tremor struck at 10:45 a.m., just over 60 miles to the west-southwest of Humboldt County’s Ferndale ...
The National Weather Service said that the tsunami warning that extended along 500 miles (800 km) of the California and Oregon coasts was called off about 90 minutes after the earthquake struck at ...
A magnitude 4 earthquake rattled Southern California before dawn Sunday morning — the strongest in a series of modest earthquakes to strike near the Ontario International Airport in the last month.
The recurrence interval for a series of large earthquakes starting in 1899 (including the 5.9 1937 Terwilliger Valley earthquake) was 18, 5, 14, 5, 12, 14, and 19 years, yet there has not been a strong earthquake for 37 years (since the 1987 Superstition Hills and Elmore Ranch sequence).
The same report also estimated there is a 7% probability that an earthquake of magnitude 8.0 or greater will occur in the next 30 years somewhere along the San Andreas Fault. [24] A different USGS study in 2008 tried to assess the physical, social and economic consequences of a major earthquake in southern California.
