Historic earthquakes discovered along San Andreas Fault
Blog—A new U.S. Geological Survey study offers a view into the past behavior of large earthquakes along the southern San Andreas Fault.
In the study, USGS geologist Kate Scharer and her team excavated trenches across the fault near Frazier Mountain in northeastern Ventura County. This section of the San Andreas previously had no long paleoearthquake record. The researchers found evidence of 10 ground-rupturing earthquakes on this section of the fault between 800 A.D. and the last rupture in 1857.
When combined with the other San Andreas Fault records, the new study represents one of the most significant records of Earth’s past earthquakes. The study is important for understanding both earthquake recurrence and earthquake hazards in California, according to the authors…more
