A moderate-sized earthquake (Ms 5.8) earthquake on 30 March 1986 was associated with surface rupture near Marryat Creek in northernmost South Australia, 300 krn southwest of Alice Springs. The fault scarp is shaped like a chevron that points toward the northeast. The north-south limb of the scarp is about 7.5 km long, and the WSW-ENE limb is 5.5 km long. Results of detailed surveying of the fault scarp give the shape and vertical displacement of the scarp at points along its full length.
