California-Nevada Fault Map centered at 37°N,122°W


Take note of the two moderate earthquakes near the Bay Area. One, a 4.1 magnitude is on the Hayward Fault, and this morning's, just before 1 am, is on the San Andreas fault. That one is a 4.5 mag. Does this mean that the two faults exchange energy, movement and stresses? Are these two quakes precursors to another future event?

These things I do not know, but I do know that there is a team of scientists in the Bay Area that have their instruments set up near Alum Rock, near where the 4.1 happened.

I will give this team a call to see if their instruments indicate anything just before the two earthquakes. You see, they are trying to measure energy emissions from rocks just before they fail. These measurements are being taken from faults throughout California and even abroad. NASA/Aimes is working closely with this team, and their experiments consist of taking rocks to their breaking point in the lab, doing so with gradually applied pressure. The NASA team is looking for the same kind of emissions from their rocks. You can read some white papers on these observations and theories at http://www.quakefinders.com

Asking these questions about these two earthquakes does not mean that I believe that they are precursors, it's just me asking some questions. And there has not been a conclusion made yet, by the science community on possible precursors to large earthquakes. It is indeed something that needs to addressed. A possible earthquake warning system could prepare communities or individuals for an event. I will blog much along these lines!
