 | An effort to map offshore portions of the San Andreas fault could help scientists better understand past earthquakes -- and the potential for future ones. ...> Full Article |
Earthquakes have rocked the powerful San Andreas fault that splits California far more often than previously thought, according to UC Irvine and Arizona State University researchers who have charted temblors there stretching back 700 years.

California's San Andreas fault is notorious for repeatedly generating major earthquakes and for being on the brink of producing the next "big one" in a heavily populated area. But the famously violent fault also has quieter sections, where rocks easily slide against each other without giving rise to damaging quakes.

 | Recent collaborative studies of stream channel offsets along the San Andreas Fault by researchers at Arizona State University and UC Irvine reveal new information about fault behavior -- affecting how we understand the potential for damaging earthquakes. ...> Full Article |
 | When the sun and moon are aligned with the San Andreas Fault they tug on it enough to increase the tremor rate deep underground, according to a new UC Berkeley study. While these tremors have not yet been linked to earthquakes, the tremors are associated with increased stress on the fault and may increase the risk of future quakes. The ease with which the deep rock slips indicates it is lubricated by high-pressure water. ...> Full Article |
When small earthquakes shake the central US, citizens often fear the rumbles are signs a big earthquake is coming. Fortunately, a new Northwestern University study instead shows that most of these earthquakes are aftershocks of big earthquakes (magnitude 7) in the New Madrid seismic zone that struck the Midwest almost 200 years ago. Aftershocks go on until the fault recovers, which takes much longer in the middle of a continent.

 | Scientists at the Carnegie Institution have found a way to monitor the strength of geologic faults deep in the Earth. This finding could prove to be a boon for earthquake prediction by pinpointing those faults that are likely to fail and produce earthquakes. Until now, scientists had no method for detecting changes in fault strength, which is not measurable at the Earth's surface. ...> Full Article |

Seismologists are re-evaluating the earthquake potential of the Central Coast, a very complex tectonic region located west of the San Andreas Fault, between Monterey Bay and the Western Transverse Ranges. This area of increasing population growth ranks as one of the top 40 US metropolitan areas with significant earthquake risk.
