In a new finding utilizing GPS data, the San Andreas Fault has a 125-mile-wide “lobe” of “uplift and subsidence”. For years, vertical motion had been ignored because of the difficulty in interpreting the “noisy data” in tectonic investigations.
Crustal movement has been predicted using computer models simulating the San Andreas Fault System, but this new data shows vertical lift. EarthSpope Plate Boundary Observatory GPS data showed that over the past several years, the lobes that are on either side of the fault line have annual movement of a few millimeters.
Researcher Samuel Howell described it, “We were able to break down the noisy signals to isolate a simple vertical motion pattern that curiously straddled the San Andreas fault.”
With the recent seismic activity in California and Yellowstone, this type of modeling will be helpful in determining when and perhaps where along the San Andreas, the Big One could hit.
The 5.2-magnitude quake in Borrego Springs, woke up many sleepy Southern California homes. This quake was followed by 800 aftershocks. This number is abnormally high for aftershocks.
Head northeast, toward Yellowstone National Park and Montana, where just this past week, several quakes have hit the region. A magnitude 3.7 quake hit on June 9th, magnitude 4.3 on June 13th and on June 15th, a magnitude 4.0 shook the region.
Though Yellowstone is hit by earthquakes all the time, as it sits upon the Yellowstone super volcano, most of these quakes are extremely small. These higher magnitude quakes are unusual and disconcerting.
Drills are being conducted in the Pacific Northwest to prepare the area for an unprecedented earthquake disaster.
To prepare the Pacific Northwest for such an enormous disaster, the U.S. government has developed alongside the military and state and local emergency personnel a readiness drill the second week of June, a dress rehearsal for the prophesied massive earthquake and tsunami.
Cascadia Rising is what this readiness drill is being called, named after the 600-mile-long fault, the Cascadian Subduction Zone, which runs from Northern California to Southern British Columbia. The drill will involve 20,000 people, utilizing a wide range of governmental agencies, with the goal to test how well these agencies will work to decrease the loss of life and the destruction such an earthquake would leave.

Bye Bye California!
California , the land of fruits and nuts
Lets hear it for the big one!
Hey I am in cali and all I can say is I hope it splits me from sacramento area because thats where hell on earth lives and maybe drop a huge$#%&!@*stone on Senator Pan and Governor Brown.
Hard to get out when they keep the poor in the state of poverty while killing our children and taking them from us when we do not comply
good
Don’t judge all of CA by the actions of a few jerks. Every state has good and bad. There are many beautiful places in CA. as well as some really nice people. The problem not everyone gets to see that side of CA. But for those nice folks in CA, if you ever get the chance to toss Gov Moonbeam off a cliff, go for it.
Good
I will lose family but I warned them to get out!!
Please fall off into the Pacific Ocean. And take all your liberal pieces of c**p with you.
