Tectonic Summary

mapEarthquake Summary Small globe showing earthquakeSmall map showing earthquake Tectonic Summary The greater Los Angeles area earthquake of 29 July 2008, 11:42 PDT (18:42 UTC), was centered in the hills south of Diamond Bar and Chino Hills. An early analysis of the earthquake's focal mechanism implies that the shock originated as the result of oblique-reverse faulting, in which a block of crust is thrust up and over the crust on the opposite side of the fault and also moves sideways with respect to the crust on the opposite side of the fault. This style of faulting is intermediate between pure reverse faulting and pure strike-slip faulting. The epicenter is in a region of the greater Los Angeles area in which both significant reverse faulting (the Puente Hills thrust) and right-lateral strike-slip faulting (the Whittier fault) have been documented. The early focal-mechanism is thus consistent with the shock having occurred as the result of stresses similar to those which produced previously mapped faults in the earthquake region. At present, however, the shock has not been associated with a specific geologically mapped fault. The 29 July 2008 was situated about 30 km east-southeast of the Whittier Narrows earthquake of 1 October 1987, which had a magnitude of 6 and which produced over $358 million in damages. The Whittier Narrows earthquake occurred as the result of thrust-faulting (reverse-faulting on a shallowly dipping plane) on the Puente Hills thrust. MAP
