Abstract

The mechanism of the May 2, 1983, Coalinga, California earthquake determined from long-period surface waves and first-motion data is given by dip angle = 65º, strike = N58°W, rake = 70°, seismic moment = 5.4 x 10^(25) dyne-cm (M_w = 6.4), and the source process time ≃ 20 sec. The local magnitude, M_L, is estimated to be 6.43 ± 0.27. On the M_L vs. M_w diagram, the Coalinga earthquake falls on the average trend for California earthquakes.
