On Tuesday, an earthquake was felt across the Bay Area in California.

The United States Geological Survey (USGS) reports that the epicenter of the earthquake with a magnitude of 5.1 was situated on the Calaveras Fault, which is located about 12 miles east of San Jose.

The Calaveras Fault extends for more than 80 miles, beginning south of Hollister and ending in the Danville-Walnut Creek area. It was around 11:42 in the morning local time when the earthquake occurred at a depth of 8.4 kilometers.

According to data provided by the USGS, an aftershock with a magnitude of 3.1 occurred in the region at 11:47 a.m., and an aftershock with a magnitude of 3.5 occurred in the same location at 3:08 p.m.

The UGCS reports that there were neither injuries nor property damage that were immediately reported.

A seismologist from the USGS named Dr. Annemarie Baltay said in a video that there is a “1 in 100 chance of an aftershock greater than magnitude 5 in the next day; there could be 10 to 15 aftershocks of magnitude 3 or greater in the next week.”

According to Dr. Baltay, “aftershocks of this magnitude and duration are totally normal for an event of this type.”

The United States Geological Survey (USGS) recorded the previous  Calaveras Fault earthquake in October 2007 and estimated that there is an 11% chance that the region may generate an earthquake of magnitude 6.7 or higher over the next 30 years. Before the shaking began, the Earthquake Warning California app had alerted around 95,000 people
