The epicenter of the quake was 31 km west of Kerinshah at a depth of 10 km.
Data from the USA natural hazards agency, which collects seismic activity from around the world, also detail two 4.3 magnitude earthquakes in the Diyala region, Iraq, close to the town of Mandali. According to Iran's state TV, the western province of Kermanshah was hit by a strong natural disaster.
