A magnitude 3.8 earthquake rattled Alameda County on Thursday morning, according to the U.S. Geological Survey. The quake hit at 8:30 a.m., centered about two miles north of San Leandro, at a depth of 3.2 miles. The USGS initially reported the magnitude as 4.1 before downgrading it to 3.8. Weak to light shaking was reported across parts of the Bay Area, based on a USGS community map.
This wasn’t a big one, but it’s a reminder that the Bay Area and the greater Sacramento region sit in active seismic territory. For morning commuters and folks heading to work, the shaking was enough to pause for a second, but there have been no reports of damage or injuries. The USGS often updates preliminary reports as more seismic data comes in, which explains the magnitude change from 4.1 to 3.8.
For those of us in the Sacramento area, it’s a good excuse to think about our own preparedness. While we’re a bit further from the San Leandro epicenter, earthquake readiness is a year-round habit here. Do you have a kit in your car or at home? Did you feel any shaking this morning? Drop a comment and let us know where you were when the ground moved.
