LA Earthquake Swarm: Strong Series of 4 Point Plus Mag Quakes

Over the past 24 hours, and especially this morning, there has been frequent 4 mag plus earthquakes in one small area, which around Yorba Linda.

This Orange County city is right on the Whittier Fault, which I feel is an extension of the larger and very active Elsinor Fault. The Whittier fault has recently kicked off a 5.3, and years ago kicked of a 6 mag plus earthquake that killed a woman.

The previous strong quakes above mentioned did not have as strong of an earthquake series as today's swarm. This makes the swarm of profound interest to the geoscience community. It is also on the same fault system where there is a extended swarm of 4 mag plus earthquakes south of Mexicali. This line in that area kicked off a 7.2 mag earthquake a couple years ago, on April 4, 2010 at 4 pm.

I don't want to end up being an alarmist, because we have not perfected detecting earthquake precursors as of yet, but I will indeed encourage people to stock up on two weeks per person of water and non-perishable foods.

I have my doubts about FEMA being timely with help, especially with our current political set up, and I'd hate to see people suffer like they did after Katrina. So go out right now and stock up on water in each car, and in the house, and get your essential medications and other life supporting supplies into a backpack and with you or in your car. Please take care of yourselves. You should do this at all times in a seismic region, anyways.

I suggest watching live seismograms for that can be interesting. I suggest the i Phone apps for that, or UCSD geo-sciences live seismogram for that. Palomar College, in San Marcos has one too.
