THE ERZINCAN EARTHQUAKE OF 13 MARCH 1992 IN EASTERN TURKEY

The 13 March 1992 Erzincan earthquake, M=6.8, occurred in the eastern half of the Erzincan basin. The largest aftershock took place near Pul umur on 15 March 1992. No clear surface breaks were observed, although teleseismic studies suggested that it was a strike-slip earthquake st riking parallel to the North Anatolian fault, with a focus of approxim ately 10+/-2 km depth, 30 km rupture length, 95 cm of slip, and a 1.16 x 10(26) dyn.cm seismic moment. The aftershock distribution concentra ted at an area of the intersection between the North Anatolian fault a nd the Ovaclk fault. These results indicate that the previously sugges ted seismic gap along the North Anatolian fault, east of Erzincan, sti ll remains unruptured.
