San Francisco Bay Space is rocked by a 5.1-magnitude earthquake

- A 5.1 magnitude earthquake struck the San Francisco Bay Area on Tuesday morning
- The quake struck at 11:42 a.m. with an epicenter in Santa Clara, California
- This was immediately followed by a 3.1 magnitude aftershock
- It is the strongest earthquake to hit the region since a 6.0 magnitude quake hit Napa in 2013
The San Francisco Bay Area was rocked by a 5.1 magnitude earthquake that shook buildings and shattered windows.
The quake struck on the Calaveras Fault at 11:42 a.m. with its epicenter in San Jose, California.
Preliminary reports from the US Geological Survey show it was 4.2 miles deep, making it a shallow quake.
It was widely felt throughout the Bay Area, with residents as far north as Fairfield, as far east as Stockton, and as far south as Salinas reporting shaking.
The earthquake was then followed 3.1 magnitude aftershocks, but the National Weather Service has said it doesn’t expect any tsunamis to follow.
It is now the strongest earthquake to hit the region since a magnitude 6.0 quake struck Napa in 2014, damaging buildings and injuring more than 100 people.
But neither San Jose nor Santa Cruz officials have yet reported any injuries or damage.

Several Californians reported that the new Shake Alert system gave them about five to 10 seconds to prepare for the quake before it struck.
As a result, some buildings across the Bay Area were evacuated as residents feared the earthquake would cause massive damage.
According to the Earthquake Information Center, California experiences two or three earthquakes every year.
The California Governor’s Office of Emergency Services is now working with local authorities in the area to assess any preliminary damage or problems that have arisen as a result of the quake and provide necessary state-level assistance.
Meanwhile, Caltrain and the Santa Clara Valley Transportation Authority are now operating at reduced speeds, and the VTA announces it is conducting a post-earthquake survey of their tracks.
