Latest San Jacinto Fault Zone Stories

Scientists Gather To Discuss Possibility Of San Diego Quakes
2012-04-13 06:55:48

Things could get shaky as scientists will gather in San Diego next week to present their latest seismological research at the annual conference of the Seismological Society of America (SSA). This year´s conference is expected to have record numbers, as well as a special public town hall meeting which will feature talks on the seismic dangers in San Diego as well as the threat of future earthquakes and tsunamis. As the city of San Diego sits on top of a fault system, there is a...

The San Jacinto Fault (SJF) Zone is a seismically active, major component of the overall southern San Andreas Fault system. Researchers from San Diego State University (SDSU) and U.S. Geological Survey have mapped evidence of past ruptures consistent with very large earthquakes along the Clark Fault, an individual strand associated with the SJF. James Barrett Salisbury, now at Arizona State University and formerly a graduate student at SDSU, and his colleagues mapped the terrain by using...

New technologies developed by NASA and other agencies are revealing surprising insights into a major earthquake that rocked parts of the American Southwest and Mexico in April, including increased potential for more large earthquakes in Southern California. At the fall meeting of the American Geophysical Union in San Francisco, scientists from NASA and other agencies presented the latest research on the magnitude 7.2 El Mayor-Cucapah earthquake, that region's largest in nearly 120 years....

New NASA airborne radar images of Southern California near the U.S.-Mexico border show Earth's surface is continuing to deform following the April 4 magnitude, 7.2 temblor and its many aftershocks that have rocked Mexico's state of Baja California and parts of the American Southwest."¨"¨The data, from NASA's airborne Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR), reveal that some faults in the area west of Calexico, Calif., have continued to move at Earth's surface,...

NASA has released the first-ever airborne radar images of the deformation in Earth's surface caused by a major earthquake -- the magnitude 7.2 temblor that rocked Mexico's state of Baja California and parts of the American Southwest on April 4. The data reveal that in the area studied, the quake moved the Calexico, Calif., region in a downward and southerly direction up to 80 centimeters (31 inches). A science team at NASA's Jet Propulsion Laboratory, Pasadena, Calif., used the JPL-developed...

With an average of four mini-earthquakes per day, Southern California's San Jacinto fault constantly adjusts to make it a less likely candidate for a major earthquake than its quiet neighbor to the east, the Southern San Andreas fault, according to an article in the journal Nature Geoscience. "Those minor to moderate events along the San Jacinto fault relieve some of the stress built by the constantly moving tectonic plates," said Shimon Wdowinski, research associate professor at the...

Scientists released the first official statewide forecast of earthquake probabilities for California Monday, reporting a 99 percent probability of a strong and damaging earthquake of magnitude of 6.7 or greater occurring along one of the state's major seismic faults within the next 30 years. The report, submitted by federal and state seismologists, geologists and geophysicists, said there was a 46 percent chance of an even more damaging magnitude 7.5 or greater earthquake occurring during the...
