(CNN) — An earthquake with a magnitude of at least 6.3 struck southeastern Iran on Monday night, according to seismologists in that country and internationally.

There were no immediate reports of damage or injuries, according to Iranian state-run Press TV.

The Iranian Seismological Center, based at the University of Tehran, reported that the quake came in at magnitude 6.5. The U.S. Geological Survey said the temblor was a slightly weaker 6.3 magnitude.

The quake occurred at 10:12 p.m. (1:42 p.m. ET), the Iranian center reported. It was centered in Kernan province about 16 kilometers (9 miles) southwest of Hosein Abab, 213 kilometers southwest of Zahedan and 540 kilometers north of the Omani capital of Muscat. Tehran, Iran’s capital, is about 1075 km to the south.

Residents of Zahedan, Khash, Iranshahr and Sistan-Baluchestan, which borders Afghanistan and Pakistan, all felt the quake, the semi-official Fars news agency reported.

Iran lies on a series of seismic fault lines and experiences earthquakes almost daily. At times, they have had devastating consequences. Among the most notable was in December 2003, when a 6.6-magnitude quake devastated the ancient city of Bam — also in southeast Iran — and killed at least 30,000 people.

Last year, an earthquake struck Hormozgan province in southern Iran, injuring about 700 people in the port city of Bandar Abbas, state media reported.

And there’s been plenty of activity in recent months as well. In early November, a 4.9-magnitude earthquake in the northwestern Lorestan province injured at least 80 people, state-run Islamic Republic News Agency reported.

One person died two months earlier when a quake measuring magnitude-5.5 struck southern Iran, and in August three were killed after a 5.7-magnitude tremor in northern Iran, state news agencies reported.
