A magnitude 3.1 earthquake rattled the East Bay, particularly an area close to San Ramon, early on Tuesday morning, as reported by the United States Geological Survey (USGS).
The quake struck just before 6 a.m., with its epicenter located approximately 3 miles southeast of San Ramon. Residents in the eastern part of San Ramon experienced a short but noticeable rolling sensation that lingered for a few seconds.
Interestingly, this recent tremor occurred in the vicinity of a series of minor earthquakes that had previously unsettled the East Bay region last week. Officials from the USGS indicated that these small quakes are typically part of the area's normal seismic activity, suggesting that such movements are not uncommon.
As of now, there have been no immediate reports of any damage resulting from this earthquake, which is reassuring news for local residents.
