CAJON PASS, CA. (Pain In The Pass) >> Stress along the San Andreas and the San Jacinto faults in Southern California has reached the highest levels in 1,000 years, according to new research from the University of Hawaii at Manoa.
They still can’t predict the time or date or location, a eathquake will strike.
The study outlines implications for seismic hazard assessments in one of the nation’s most populated and infrastructure-critical regions.
If a large quake around the Cajon Pass that the San Andreas Fault converges with the San Jacinto Fault nearby. The San Jacinto Fault ends near the Lytle Creek area, the fault runs through San Bernardino, Riverside, San Diego, and Imperial Counties. Scientist Liliane Burkhard said that “the region may be capable of a large through-going rupture involving both fault systems,” and that researchers “also found that the Cajon Pass may act as an ‘earthquake gate.’ They said, sometimes blocking large ruptures from crossing between the faults, and sometimes allowing them to pass through and involve both systems in a single event.” This could cause a mega quake or two large quakes.
A rupture crossing both faults would be far larger, longer, and more destructive than one confined to a single fault, so threatening life is large cities like Los Angeles, San Bernardino, Riverside and the Coachella Valley, among the most densely populated areas in the US.
The Cajon Pass scenario if a large quake happens the Cajon Pass Interstate 15 Freeway could be blocked thought traffic from San Bernardino to the high desert community for months. Cajon Pass in the gateway into the desert interior of California and Las Vegas, Nevada.
They said, if a magnitude 7.8 quake were to hit the southern San Andreas, geologists expect it would cause 1,800 deaths, 50,000 injuries and $200 billion in damage.
Experts hope the study could serve as extra motivation to take the big one a little more seriously.
