The last 5 strong earthquakes happened in the target areas that S.O. said they would. They are releasing an App to predict disasters. Since I live 50 miles from the Palmdale bulge, this is of special interest to me. There are only 4 roads into L.A. and all of them have many bridges and high overpasses.
The San Andreas fault does continuous slip but, the Palmdale bulge keeps it locked until it does a violent slip-catch. The rest of the fault has creeped 35 meters since the great Tejon earthquake of 1857. The next slip-catch is expected to hit a terminal velocity of 55 mph with lateral accelerations of 3g
We are at the longest interval for the periodicity of the San Andreas fault. The Southern San Andreas fault by the Salton Sea is about 300 years overdue for release. It is expected to kick off it's northern cousin when it lets go. The fault is 250 miles deep so, there will be hundreds of cubic miles of rock breaking loose and then, slamming to a stop.
