Magnitude 4.5 earthquake shakes San Francisco Bay area days before Loma Prieta anniversary – USA TODAY
A magnitude 4.5 earthquake in the San Francisco Bay Area Monday evening rattled residents, mere days before the 30th anniversary of one of the most dangerous earthquakes in the area’s history.
The quake occurred at 10:33 p.m., with the epicenter in Pleasant Hill and Walnut Creek, just over 25 miles from San Francisco, according to the U.S. Geological Survey.
Weak shaking was felt in San Francisco, Oakland and San Jose, per the USGS. A 2.5 magnitude foreshock also took place 10 minutes earlier near Pleasant Hill.
Scientists don’t anticipate major structural damage, but people who reside by the epicenter reported minor damage.
USGS geologist Keith Knudsen, who serves as the deputy director of the agency’s Earthquake Science Center said that the earthquake had a preliminary depth of about 9 miles underneath the surface, which he says is fairly deep for this area. The more shallow the earthquake, the more damaging they tend to be, according to the USGS.
Mark Ulicki, a Walnut Creek resident, tweeted that there was a “big shaking” that caused broken glass and “lots of car and business alarms going off.”
The quake took place three days before the 30th anniversary of the 1989 Loma Prieta earthquake. The 6.9 magnitude earthquake killed 63 people and injured thousands.
Many locals took to Twitter to share their unease at Monday’s earthquake taking place almost exactly three decades after the deadly shock.
Assistant Chief Chris Bachman of the Contra Costa County Fire Protection District said that there were no reports of injuries or property damage caused by Monday’s earthquake as of 11 p.m. that day.
In early October, a magnitude 3.5 earthquake shook the Bay Area in the town of Colma, located just south of San Francisco.
