1968 Dasht-e Bayaz and Ferdows earthquakes

The Dasht-e Bayaz and Ferdows earthquakes (Persian: زمین‌لرزه ۱۳۴۷ دشت بیاض و زمین لرزه فردوس) occurred in Dashte Bayaz, Kakhk and Ferdows, Iran in late August and early September 1968.

The Iranian plateau is confined by the Turan platform in the north and the Zagros fold and thrust belt and Makran Trench in the south.

The Arabian plate is converging to the north with the Eurasian plate at a rate of 35 millimeters (1.4 in) per year, and is diffused across a 1,000 km (620 mi) zone resulting in continental shortening and thickening throughout the plateau, with strike-slip and reverse faulting present, as well as subduction at the Makran coast.

A strong aftershock on 1 September, measuring 6.4 on the moment magnitude scale, destroyed Ferdows.
