The San Francisco Bay Area experienced a minor earthquake on Thursday, according to the United States Geological Survey (U.S.G.S.). The earthquake, registering a magnitude of 3.2, struck at 7:27 a.m. Pacific Time.
Data from the U.S.G.S. indicates that the epicenter of the temblor was approximately 2 miles southeast of San Ramon, California. While considered a minor earthquake, residents in the surrounding areas may have felt the shaking.
Aftershocks and Seismic Activity
Seismologists are currently reviewing the data collected from the event and may revise the earthquake's reported magnitude as more information becomes available. The U.S.G.S. may also update the shake-severity map based on new data.
An aftershock is a smaller earthquake that follows a larger one in the same general area. These aftershocks represent minor adjustments along the fault line that initially slipped during the main earthquake. Aftershocks can occur days, weeks, or even years after the initial event, sometimes reaching equal or even larger magnitudes. This can further impact already damaged areas.
Understanding Earthquake Data
The U.S.G.S. utilizes the Modified Mercalli Intensity scale to categorize shaking intensity. When aftershock data is available, maps and charts include earthquakes within 100 miles and seven days of the initial quake. All times reported are Pacific Time.
