The 1983 Coalinga main shock occurred beneath the Coalinga anticline, about 45 km east of the San Andreas near the boundary between the San Joaquin Valley and the southeastern Diablo Range of the central California Coast Ranges. The main shock and most aftershocks occurred 6 to 14 km beneath the Coalinga anticline-Pleasant Valley syncline area. The main-shock epicenter was about 10 km northeast of the town of Coalinga, near the axis of the Coalinga anticline. The aftershock epicenters form an elliptical pattern, about 35 km long from Nunez Canyon on the northwest to the Guijarral Hills on the southeast, and about 15 km wide from Coalinga on the southwest to the main-shock epicenter. This pattern includes most of the southeast-plunging Coalinga anticline but lies south of contiguous, east-southeast-plunging Joaquin Ridge. This chapter outlines aspects of the structural history, seismicity, and inferred stress regime of the Diablo Range-San Joaquin Valley region.
