In southern California discovered a new fault


After a major series of more than 200 earthquakes recorded in California lake the Salton sea, researchers have needed only a few days to discover the coast of pond new tectonic fault. The crack runs parallel to the fault the San Andreas fault and, according to team scientists from SCRIPPS institution of Oceanography seismological laboratory and Nevada, is a new danger in southern California.

According to experts, the location of the fault beneath the sedimentary rocks of the reservoir and the prior lack of related seismic events are not allowed to make the discovery earlier. To download the crack, scientists need to use a wide range of tools, including multi-channel seismic data and geophysical techniques.

According to seismologists, recent studies have shown that over the last 1000 years of earthquakes of magnitude 7.0 and above have occurred in southern California between 175 to 200 years. However, it used to be. For the last 300 years in the southern part of the fault, the San Andreas was not a single tear, so researchers believe that this region is long overdue for a major quake.

A series of small earthquakes of magnitude 4.3 occurred on the Salton sea last week prompted experts to declare the Advisory warning for southern California and to increase the estimated risk for earthquakes of magnitude above 7.0 from 1:3000 to 1:100. Warning was announced until October 4. On Wednesday, October 5 emergency Management California has officially stated that the Advisory period is completed.

For those who live in southern California, the abolition of the Advisory warning is of little consolation because the southern part of the fault the San Andreas is still locked and ready to break, and the detection of a new fault at the Salton sea only increases their fears. Experts hope that a crack was found, named the Salton sea, will have an impact on the existing model of seismic risks in the area and will help to make more accurate predictions of earthquakes.
