Earthquake: Magnitude 3.3 quake hits the San Fernando Valley

A magnitude 3.3 earthquake shook up the San Fernando Valley on Sunday morning.

The epicenter of the earthquake, which hit at 3:19 a.m., occurred in Chatsworth. Light shaking was felt in the northwest section of the Valley, while weak shaking was felt in the rest of the Valley and into downtown Los Angeles and the Westside, according to the U.S. Geological Survey.

Light shaking, as defined by the Modified Mercalli Intensity Scale, can wake people up and rattle dishes and windows, can rock stationary motor vehicles, and can feel like a truck hitting a building.

Within 20 minutes of the earthquake, hundreds of people reported feeling the earthquake and reported it to the USGS’ Did You Feel It? crowdsourcing survey. Residents reported feeling it as far away as Simi Valley, Santa Clarita and Santa Monica.

In the last 10 days, there have been no earthquakes of magnitude 3.0 or greater centered nearby.

An average of five earthquakes with magnitudes between 3.0 and 4.0 occur per year in the greater Los Angeles area, according to a recent three-year data sample.

The earthquake occurred at a depth of 4.3 miles. Did you feel this earthquake? Consider reporting what you felt to the USGS.
