A magnitude 3.6 earthquake focused in Granada Hills struck at 11:41 p.m. Tuesday, causing light shaking throughout the San Fernando Valley as well as weaker shaking in other places in the L.A. region.

Besides the Valley, shaking might be felt in Santa Monica, Marina del Rey, Los Feliz, Silver Lake, the Hollywood Hills, downtown L.A., the San Gabriel Valley, Santa Clarita and Ventura County.

The Los Angeles Fire Department stated there were no early reports of significant damage or injury, however as a basic precaution officials are patrolling the area with automobiles and helicopters.

The centre of the earthquake was in the location of the Van Norman Lakes Reservoir, near the intersection of the 405, 5 and 118 freeways. Van Norman dam was changed after the magnitude 6.6 Sylmar earthquake in 1971 almost caused a collapse and forced a sweeping evacuation of 80,000 people; its replacement dam survived the magnitude 6.7 Northridge earthquake of 1994 without any damage.

Lots of earthquake faults lie below this part of the L.A. region, such as strands of the Sierra Madre fault zone.

An average of five earthquakes with magnitudes from 3.0 to 4.0 happen annually in the greater Los Angeles area, according to a recent three-year information sample. Tuesday night's earthquake occurred at a depth of 4.3 miles.
