TEHRAN, Jan. 29 (UPI) -- A light earthquake rattled southeastern Iran early Saturday near the epicenter of a strong earthquake two days ago, the U.S. Geological Survey reported.
The 4.6-magnitude quake struck just after 8 a.m. 75 miles south-southeast of Bam and almost 700 miles southeast of Tehran, the USGS said. A 6.0-magnitude quake hit in the same location just after noon Thursday.
The Fars news agency put the magnitude of Saturday's quake at 5.0, citing Iranian seismologists. The agency said there were no reports of damage or casualties.
Earthquakes in the magnitude 5 range can cause damage in poorly built structures, while those of 6 or more can do significant damage.
Bam was hit by an earthquake in December 2003 that killed about 30,000 people and destroyed the city's most prominent feature, its mud-brick citadel, which had been built before 500 B.C.
