Update: The earthquake was recently downgraded to a 3.1, and a smaller earthquake measuring 2.7 (originally 2.8) on Sunday the 28th, occurred nearby.

At 7:52 pm, a magnitude 3.2 earthquake occurred in Playa Del Rey, just south of the Ballona Wetlands.   The quake had a depth of 8 miles and had an intensity of IV on the Mercalli Scale near the epicenter. The quake's epicenter was near the location of the 3.7 earthquake in Westchester, in July of last year. At my location just to the north I felt light shaking for approximately three seconds (my quakealarm went off), and then a sharp jolt.

The light shaking I felt was the P-wave, while the jolt was the S-wave of the earthquake. This time difference is used in earthquake early warning technology. As you have heard, the P-wave is usually not felt as strongly, while the S-wave is the stronger and causes most of the damage during a large earthquake.
