An earthquake measuring 3.9 on the Richter scale struck an area near the town of Aliabad in Golestan province, Northern Iran, on Friday, IRNA reported.
The Seismological center of Golestan province affiliated to the Geophysics Institute of Tehran University registered the quake at 17.24 hours local time (1254 GMT).
The epicenter of the quake was located in an area 54.94 degrees in longitude and 36.74 degrees in latitude.
Iran sits astride several major faults in the earthˈs crust, and is prone to frequent earthquakes, many of which have been devastating.
The worst in recent times hit Bam in Kerman province in December 2003, killing 31,000 people - about a quarter of its population - and destroying the cityˈs ancient mud-built citadel.
The deadliest quake in the country was in June 1990 and measured 7.7 on the Richter scale. About 37,000 people were killed and more than 100,000 injured in the northwestern provinces of Gilan and Zanjan. It devastated 27 towns and about 1,870 villages.
In August 2012, two quakes in Northwestern Iran also claimed the lives of 306 people and injured more than 4,500 others.
