Magnitude 3.5 £qrthquake beneath northern Los Angeles.

The United States Geological Survey recorded a Magnitude 3.5 Earthquake at a depth of about 3 km beneath the Pacoima district of Los Angeles, California, slightly before 3.00 am local time (slightly before 11.00 am GMT) on Thursday 5 November 2015. There are no reports of any damage or injuries relating to this quake, but people have reported feeling it across much of the Los Angeles area.

California is extremely prone to Earthquakes due to the presence of the San Andreas Fault, a tectonic plate margin that effectively bisects the state. The west of California, including Santa Barbara and Los Angeles, is located on the Pacific Plate, and is moving to the northwest. The east of California, including Fresno and Bakersfield is on the North American Plate, and is moving to the southeast. The plates do not move smoothly past one-another, but constantly stick together then break apart as the pressure builds up. This has led to a network of smaller faults that criss-cross the state, so that Earthquakes can effectively occur anywhere.

Witness accounts of Earthquakes can help geologists to understand these events, and the structures that cause them. The international non-profit organization Earthquake Report is interested in hearing from people who may have felt this event; if you felt this quake then you can report it to Earthquake Report here.
