A seismological base in Yazd registered a quake at 03:40 Thursday (2310 GMT Wednesday) 30 km to the southeast of Tabas.
At least 25,000 people were killed in a 7 plus-degree earthquake which struck Tabas in September 16, 1978.
Iran sits on some of the world's active seismic faultlines and tremors of mild magnitude are almost a daily occurrence.
Since 1991, at least 17,000 Iranians have died in earthquakes.
