There’s a hole in this possible earthquake pattern

As UC Davis physicist and geologist John Rundle ponders the map of recent California earthquakes, he sees visions of a doughnut even Homer J. Simpson wouldn’t like.
The doughnut is formed by pinpointing the recent quakes near Eureka, Mexicali and Palm Springs.
Seismologists call the possible pattern a Mogi doughnut. It’s the outgrowth of a concept, developed in Japan, which holds that earthquakes sometimes occur in a circular pattern over decades —building up to one very large quake in the doughnut hole. Rundle and his colleagues believe that the recent quakes, combined with larger seismic events including the 1989 Loma Prieta and 1994 Northridge temblors, could be precursors to a far larger rupture.
Irvine Co. gives 20,000 acres of open space to Orange County
Posted in News, Science, what on June 30th, 2010 by admin – Comments OffA rugged, 20,000-acre parcel of the original Irvine Ranch — a pristine landscape of steep canyons, native grassland and sycamore woodland that is home to golden eagles, mountain lions and dozens of rare and endangered species of plants and animals — became public property Tuesday in a historic deal with the developer who has sculpted the look of modern suburbia in Southern California.
The open-space land, a gift from Donald Bren and the Irvine Co., was unanimously accepted by the Orange County Board of Supervisors, which also approved a long-term plan to manage the natural habitat, designated a National Natural Landmark four years ago. In one swoop, the size of parkland owned by the county grew by more than half.
The transfer of a large part of the historic ranch was an important milestone, placing the last major chunk of open private land in public hands and signaling the end of an era of enormous growth for Orange County.
