San Andreas Fault study unearths new quake information (1/24/2010)

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

Sun and moon trigger deep tremors on San Andreas Fault (12/29/2009)

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

Earthquakes actually aftershocks of 19th century quakes (11/6/2009)

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. ...> Full Article

New way to monitor faults may help predict earthquakes (10/2/2009)

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

California's central coast earthquake hazards: New information about recently identified faults (4/13/2009)

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. ...> Full Article
