Hi All. The following is from the Nature science journal.
“East Pacific Rise transform faults are characterized by high slip rates (more than ten centimeters a year), predominately aseismic slip and maximum earthquake magnitudes of about 6.5. Using recordings from a hydroacoustic array deployed by the National Oceanic and Atmospheric Administration, we show here that East Pacific Rise transform faults also have a low number of aftershocks and high foreshock rates compared to continental strike-slip faults. The high ratio of foreshocks to aftershocks implies that such transform-fault seismicity cannot be explained by seismic triggering models in which there is no fundamental distinction between foreshocks, mainshocks and aftershocks. The foreshock sequences on East Pacific Rise transform faults can be used to predict (retrospectively) earthquakes of magnitude 5.4 or greater, in narrow spatial and temporal windows and with a high probability gain. The predictability of such transform earthquakes is consistent with a model in which slow slip transients trigger earthquakes, enrich their low-frequency radiation and accommodate much of the aseismic plate motion.”
I can't help but wonder how long it is going to take for all the stress that is being released at the site of the quakes to trigger quakes in California and other locations along the west coast. That stress just doesn't dissolve into nothing. It moves along getting closer and closer to California until one day the quake everyone is waiting for occurs be it on the San Andreas fault or some other fault.
Keep in mind the quake doesn't have to occur at the very southern end of California it could occur further north in the heart of Southern California. It doesn't necessary have to occur on the San Andreas fault, but on another fault much closer to densely populated areas. It doesn't even have to be a real large quake. All it needs to do is occur at the wrong time at the wrong location. That is all it really needs. Just the wrong time at the wrong location. Think about it. Are you ready? Take Care...Don
