california earthquake
For California earthquakes of Magnitude 3.5 and larger. [1]
The Uniform California Earthquake Rupture Forecast, by the 2007 Working Group on California Earthquakes, gives the first statewide estimate of earthquake probabilities for the next 30 years. [2]
The Southern California Earthquake Center (SCEC) is a community of over 600 scientists, students, and others at over 60 institutions worldwide, headquartered at the University of Southern California. [3]
Maps of recent earthquakes and Shakemaps of the intensity of earthquake shaking are available from CISN (California Integrated Seismic Network), a cooperative project of CGS, USGS, OES, Caltech and UC Berkeley. [2]
Like the clickable image, this list does not feature every earthquake ever recorded in southern California above a certain magnitude; these are selected events and they do not represent a complete list. [4]
USGS and other scientists conclude that there is a 62% probability of at least one magnitude 6.7 or greater quake, capable of causing widespread damage, striking the San Francisco Bay region before 2032. [1]
We record the strong ground motion from earthquakes, study the distribution of historic earthquakes and evaluate faults that are the source of earthquakes. [2]
Maps showing the probability of strong shaking at any location in California within the next 24-hours. [...] The centennial of the 1906 San Francisco earthquake will mark a century of progress in understanding earthquake hazards and reducing risks. [1]
We combine that information to prepare maps showing the potential for ground shaking, fault rupture, liquefaction and seismically induced landsliding. [...] The result is expressed as the probability that an earthquake of a specified magnitude will occur on a fault or within an area. [...] Studies of historic earthquakes provide basic background for projecting future seismic hazards and losses. [2]
Brown lines are known hazardous faults and fault zones. [5]
These estimates of seismic hazards can be used to estimate the effects of potential earthquakes as planning scenarios and the potential for statewide earthquake losses. [2]
Current research activities and results in seismology, crustal structure and deformation, geology and borehole physics. [1]
