A 4.5 magnitude earthquake has been reported by the US Geological Survey north of Walnut Creek on Monday, October 14, night at 10.33 pm after a smaller 2.5 magnitude quake struck the same area just 10 minutes earlier.
It was thought to be 4.7 on the Richter scale initially but was later brought down to 4.5. Areas affected were Oakland, Pleasant Hill, and Martinez and police have not received any news of injuries, loss of life or property.
According to the NOAA / National Weather Service US Tsunami Warning System, there is no tsunami warning, advisory, watch, or threat at this point.
A number of aftershocks were also reported after the bigger quake. Trains were delayed on Monday night due to the inspection of the tracks after the quake.
It was centered in Pleasant Hill. According to a report in the San Fransisco Chronicle, U.S. Geological Survey identified the quake was a result of the movement of an unmapped fault situated between Concord and Calaveras faults.
