Rush hour earthquake jolts San Francisco, second in region in 10 days

SAN FRANCISCO — A surprising 3.7 magnitude earthquake struck the San Francisco Bay Area Friday night, startling rush hour commuters as the second such tremblor in Northern California in just over a week.

The quake hit at around 6:38 p.m. local time, according to the U.S. Geological Survey, just as sunset was approaching. The USGS earthquake monitor initially put the quake at 4.1 on the Richter scale but then, as is common, the measurements slightly downwards to 3.9 and then at 3.7 as more data came in.

There have been no immediate reports of injuries or damage.

The tremblor appears to have been close to the San Andres Fault, with its epicenter documented in the town of Millbrae, near San Francisco International Airport, about 10 miles south of the city.

which could have more than the usual upset. (this is an example, not at SFO)

I am hoping for a reversal of gravity, as in this one, falling UP the stairs.
