Pair of quakes shake San Francisco Bay area

SAN FRANCISCO >> Two small, back-to-back earthquakes shook San Francisco Bay area residents awake Monday morning but appeared to leave no serious damage or injury.

The U.S. Geological Survey reported that a magnitude-2.9 quake struck at 5:33 a.m. local time about eight miles northeast of San Francisco in the city of El Cerrito. It was followed eight seconds later by a magnitude-4.0 temblor, said geophysicist Paul Caruso.

The shaking was felt within a 60-mile radius, from Santa Rosa in the north to Santa Cruz in the south.

The California Highway Patrol, San Francisco police and El Cerrito police said they didn't receive any immediate reports of injury or damage.

Bay Area commuter trains were briefly delayed after the quake to inspect the tracks.

Seismologists said the quake appeared to occur on the Hayward Fault, a seismically active fault that runs along the eastern San Francisco Bay. A 2003 USGS report said the Hayward Fault had the highest chance — 27 percent — of producing a large earthquake of magnitude-6.7 or higher in the Bay Area within 30 years.

"We know that the Hayward Fault is the really important fault in the Bay Area," USGS seismologist David Schwartz told KGO-TV on Monday. "These earthquakes, these 4's, are just an indication of ongoing activity, ongoing stress on the fault. They do nothing to relieve the likelihood of something larger happening."

Overall, there was a 62 percent probability that the Bay Area would see a large quake by 2032, according to the report.

I live in SF and the 4.0 definitely woke me up this morning. It was longer than usual and a bit spooky.

The excitement of flirting with danger is addictive to some. Not for me, and yet I live in souther California where ther are more faults than wrinkles on octogenarian. Scary, eh what. Opine better than tornado alley, like Oklahoma environs or Florida hurrican alley, or maybe tsunami prone Pacific.

I'd take the threat of tornados (I'm in KS) or a tsunami over an earthquake any day of the week. Without much doubt, in my lifetime, Cali will get hit with a massive earthquake - most likely with little or no real warning. Without much doubt the Midwest will be hit by several massive tornados, maybe even this year. The difference is that there will be warnings available that will help most people avoid the storm. There will be destruction, but the storms are definitely survivable. With some education and common sense, a tornado can be observed and avoided without being in danger. It is like surfing Pipe. If you know what you are doing, where to paddle out at, you can be safe. If I paddled out, I would be a statistic.
