3.6R Earthquake Sends Tremors Near Lake Henshaw

A preliminary 3.6 magnitude earthquake sent tremors near Lake Henshaw Tuesday morning, according to the United States Geological Survey. The quake happened at 9:21 a.m. roughly 1.5 miles southeast of Lake Henshaw. NBC 7 viewers said they felt the earthquake in El Cajon, Escondido, Kearny Mesa, La Mesa, Lakeside, Lemon Grove, Mira Mesa, Poway, Ramona, Rancho Peñasquitos, Spring Valley, and other parts of the county. According to a map by USGS, weak shaking occurred near the origin of the earthquake, and its most extreme shaking -- labeled as "light" -- occurred in the Julian area. Most of the county to the southwest experienced weak to light shaking.

The epicenter location can be seen in the map above. Below we see the stress location map we generate, and clearly, we see the location very close to it.

Finally we see the California Calendar for october, (the one we publish and produced here) where we see a peak tomorrow. (Note accuracy we hope +- 1 day).
