3.7 | 4:59pm | Santa Monica Bay, Ca. | June 7th, 2010

At 4:59pm, on Monday evening, a 3.7 magnitude earthquake hit 4 miles west of Hermosa Beach, California. Earlier in the morning, a 3.5 magnitude hit 3 miles west of Hermosa Beach, making the 3.5 a preshock to the 3.7 this evening.

The earthquake occurred just off the coast of the LA area and may be associated with either the Redondo Canyon or Palos Verdes fault zones. The epicenter was located just north of both fault systems.

Approximately an hour after the 3.7 magnitude quake, close to 3200 felt reports were given to the USGS, most of which were centered around the LA metro area. The highest number of reports, 202, came from the Manhattan Beach area. It was reported being felt as far north as Bakersfield, as far east as Riverside, and as far south as Capistrano Beach.

Due to the minor magnitude, no damage or injuries are expected.

3.9 Quake Shakes Fontana and the Inland Empire

An earthquake with a magnitude of 3.9 occurred about 4 miles north of Fontana. It struck at 1:22 a.m. Local time on March 9, 2008. An aftershock measuring 3.1 occurred about a minute later.

A quake of this size is not expected to cause damage or injuries. It was widely felt throughout the Inland Empire, Riverside and parts of Los Angeles and Orange counties.

Quakes in this area are not uncommon. A 4.4 in January of 2005 was preceded by several smaller foreshocks.
