Several cities across California were rattled by earthquakes on Memorial Day, with the strongest one recorded in the northern part of the state.

The epicenter was located 26 kilometers northeast of Viola, at a depth of -1.8 kilometers.

The epicenter is located close to other cities, including Burney (28.1 kilometers) and Fall River Mills (around 36 kilometers).

The tremor was experienced by eight persons, who reported feeling it on the USGS’s ‘Did You Feel It?’ earthquake reporting system.

While four responses were submitted near the epicenter, the earthquake was also felt at places such as Anderson (71 kilometers from the epicenter), Red Bluff (88 kilometers), and Chico (105 kilometers), according to the USGS.
