San Jacinto fault Quietens?

I've kept a USGS earthquake map on my book marks, and probably open it more often than is healthy, since before the easter Sunday 7.3.
I click on this one:


http://earthquake.usgs.gov/earthquakes/recenteqsus/Maps/US2/32.34.-117.-115.php
Then I Click on US. Then worldwide.

It only covers quakes up to a week old, but the last few days, I noticed a Lot fewer of the quakes showing up, and the ones that do are smaller, and more widely scattered.

Could this be the aftershocks just slowing down, or just that the plates just got stuck again and are building the extreme pressures for a near future large scale slippage?

CRACK!!!!!!!!!!

Cue maniacal laughing....

Having worked with Lucy Jones of the USGS, I'd say that no news is not necessarily good news.

Baja and California on the west side of the San Andreas is moving North... Has been for at least 5 million years. Cabo was once next to Puerto Vallarta. When the earth moves, you sometimes feel it... Lots of little quakes is nice movement... When things stick together for too long as the plates slide, it will eventually SNAP free... those are not nice !!

Even Cray computers cannot come close to predicting a quake. When animals start going nuts then I start to worry.

I just find it interesting that the general area has seemed to abruptly become less active.

On Easter Sunday, my neighbors Parakeet started about 15 seconds before the dogs. I happen to despise that parakeet due to continuous screeching and envision a pink and green cloud of blood and feathers every time it starts up.

But on that Sunday, I noticed a different pattern to the screeching before the bump and sway began.

I'm in agreement with bajahowodd. I watch the earthquake maps daily too and as a geologist.. A WEEK of less activity is to short a time to be significant.

Stress builds up constantly but is RELEASED infrequently. The stress is always building up..it is only Temporarily relieved IN GEOLOGIC TIME (With 4.5 BILLION YEARS of geologic time...... a week is of no consequence).

But Thank You for your interest. I am pleased that you follow the earthquake activity!
