According to a report by seismography center affiliated to Tehran University's Geophysics Institute, the tremor occurred at 13:05 hours local time (8:35 hours GMT) with its epicenter being registered at 45.81 degrees longitude and 34.42 degrees latitude and in the depth of 7 km underground.
The tremor has had no casualties or damage, said Hooshang Bazvand, governor of Kermanshah Province.
Kermanshah has been jolted by several earthquakes since November 12, 2017, when a 7.3- magnitude earthquake hit the province's Ezgeleh region killing at least 620 people and injuring over 12,000.
Iran sits on several major seismological fault lines, making it one of the world's most quake-prone countries.
