abstract

A severe earthquake in the west-central part of the Anatolian fault zone occurred on 22 July 1967, causing loss of life and widespread damage. The earthquake was associated with 80 kilometers of fresh faulting, part of which occurred in a zone ruptured ten years earlier. The sense of movement along the fault break is right lateral with the north side downthrown. Maximum relative displacements of 190 centimeters lateral and 120 centimeters vertical were measured. Damage caused by shaking in the immediate vicinity of the fault-break was equal to or smaller than that caused at some distance from the fault. Thus, proximity to the fault-break was found to be an unjustified criterion for higher intensities. The instrumental epicenter of the main shock had been located near the east end of the fault break. The bulk of the aftershocks is concentrated at the other end of the break, in the extreme west.
