Magnitude 2.9 earthquake shakes South Bay
MORGAN HILL — A magnitude 2.9 earthquake rattled the South Bay late Monday night, according to the U.S. Geological Survey.
The USGS reported the quake hit just before 11 p.m. about 7.5 miles north-northeast of Morgan Hill. It was felt as far south as Morgan Hill and as far north as Sunnyvale.
There were no immediate reports of any injuries or damage.
The quake occurred on the Calaveras Fault, which routinely releases stress caused by the earth’s shifting continental plates.
Monday’s jolt is the latest in a series of tremors triggered by this fault, which extends from just south of Walnut Creek to south of Hollister, where it joins the San Andreas Fault.
The fault last produced a notable quake in October 2007, a magnitude 5.4 that hit near Alum Rock, according to the USGS.
Activity along the Calaveras Fault gets close attention because it has a high degree of rupturing in a large magnitude quake, exceeding magnitude 6.7, over the next 30 years.
