A 4.5 magnitude earthquake shook parts of California late Monday night. The U.S. Geological Survey originally called it a 4.7 quake, but later downgraded it slightly to 4.5.
The quake struck at 10:33 p.m. Pacific time in the San Francisco Bay Area near the Calaveras fault.
A 2.5 earthquake also hit the same area moments before the 4.5, and experts said there was a slight chance of a bigger quake over the next few days.
Police said they received no immediate reports of any injuries or significant damage, but people felt the shaking throughout Northern California.
The National Weather Service in the Bay Area said there was no tsunami threat expected from the earthquake.
This quake comes just days before the 30th anniversary of the massive Loma Prieta earthquake that killed dozens of people.
The M4.5 quake at 10:33 pm was in the East Bay at 14 km depth. Because any quake can be a foreshock, there’s a slight increase in the chance of a bigger quake for the next few days, at the same location near the Calaveras fault
