A 3.8-magnitude quake hit East Bay, California, around noon on Wednesday, according to NBC Bay Area.

  • More than 3,500 people reported the quake to USGS, while others discussed it on social media.
  • So far, there are no injuries reported, as per the Sacramento Bee.

The big quake was followed by more than a dozen aftershocks ranging from magnitude 1.3 to 3.0, as per the USGS data. According to Michigan Tech University, magnitudes 2.5 or lower aren’t usually felt.

The Los Angeles Times reported that in the last 10 days, an earthquake with a magnitude of 3.0 or greater was felt in the area.
