Could recent Southern Calif. earthquake patterns offer scientists critical clues?

SAN DIEGO COUNTY – Following the earthquake that was centered near Borrego Springs on July 7, scientists at QuakeFinder – a humanitarian organization conducting research into pre-earthquake electromagnetic signals with the aim of developing an early warning system – immediately analyzed the data collected from their sensors.

While more data is being retrieved from the magnetometer’s hard drive for further analysis, there appears to be some prior magnetic pulse activity present before the magnitude 5.4 event.

The Borrego Springs area is located on the San Jacinto fault and had been active for several weeks through a cluster of small quakes, parallel to another small cluster of quakes at Ocotillo – 55 miles to the southeast along the Elsinore fault.

While both may be indications of a stress migration from the recent Easter Sunday earthquake in Baja, Mexico, QuakeFinder offers further elaboration.

“The aftershocks (or pre-shocks) are migrating up towards both the San Jacinto and Elsinore faults as the stress is relieved in one area, and then migrates up to adjacent fault segments,” said Tom Bleier, head of QuakeFinder. “However, Borrego and the Mexican border area clusters may not be where the real action is in the near future. The San Jacinto segment is already covered with three of our sites at Ocotillo Wells, Borrego Springs and Anza. If there is a larger quake at the fringe of these clusters where the stress is still building, the existing and new sites may detect the same magnetic pulsations that were observed two weeks prior to the 2009 Alum Rock M 5.4 earthquake and the 2010 Tacna, Peru events where QuakeFinder instruments were present. This could offer significant data towards the validation of existing research.”

Before it can confirm any findings, QuakeFinder needs to increase the density of the network of sensors to allow the capture and analysis of more earthquake events in order to determine if the patterns are repeatable.

In an innovative approach to the expansion of the network, QuakeFinder invites private individuals, businesses and governments to sponsor or host sites.

Anyone interested in becoming a host or sponsor can simply go to the Web site to learn more about their research.

QuakeFinder, the Humanitarian R&D division of Stellar Solutions, Inc., is located in Palo Alto, CA, and conducts pioneering research in the area of earthquake forecasting with the ultimate aim to develop, within the next decade, a global earthquake warning system.
