A strong earthquake struck Iran's southwestern province of Kohgiluyeh and Boyer-Ahmad Wednesday morning.

The temblor, measuring 5.2 on the Richter scale, rocked the city of Sisakht at 8:38 A.M. local time.

The epicenter, with a depth of 8 km, was determined to be at 30. 835 degrees north latitude and 51.559 degrees east longitude.

There have been no reports of casualties or damage yet.

Iran is one of the most seismically active countries in the world, being crossed by several major fault lines that cover at least 90% of the country. As a result, earthquakes in Iran occur often and are destructive.

The deadliest quake in Iran's modern history happened in June 1990. It destroyed the northern cities of Rudbar, Manjil, and Lushan, along with hundreds of villages, killing an estimated 37,000 people.

Bam in the country's southeastern province of Kerman witnessed a strong quake in December 2003 which killed 31,000 people.
