Magnitude 5.1 earthquake rattles San Francisco Bay Area, the largest to strike the region in year

On Tuesday, a magnitude 5.1 earthquake shook the San Francisco Bay Area, shaking buildings and causing the region's strongest quake in eight years.

There were no immediate reports of damage or injuries. The quake struck at 11:42 a.m. local time about 12 miles east of San Jose at a depth of about 4 miles, according to the US Geological Survey. The area is approximately 40 miles southeast of San Francisco.

According to USGS data and seismologist Lucy Jones, the earthquake was the largest in years in the Bay Area. In 2014, a 6.0 magnitude earthquake struck near Napa.

According to the California Governor's Office of Emergency Services, or Cal OES, nearly 100,000 people reported receiving an earthquake warning before the shaking began. The USGS reported a 3.1 aftershock about five minutes after the initial earthquake. 

The earthquake on Tuesday came just a week after the 33rd anniversary of the 1989 Loma Prieta earthquake, a magnitude 6.9 quake that struck the Santa Cruz Mountains on Oct. 17, 1989, just as the World Series was about to begin in San Francisco. The quake killed 62 people and caused billions of dollars in damage.
