The powerful earthquake hit near Qotur in Khoy County in West Azarbaijan Province.
The province is located in the northwest of the country, bordering Turkey, Iraq and Azerbaijan's Nakhchivan Autonomous Republic, as well as the provinces of East Azarbaijan, Zanjan and Kurdistan.
According to the Iranian Seismological Center, the magnitude 5.7 earthquake occurred at 9:24 AM on Sunday, at depths of six kilometers beneath the surface of the Earth.
The earthquake was also felt in Urmia, the capital of the province.
Quake-damage assessment teams have been dispatched to Qotur.
Due to low population density in this area, it is hoped that the earthquake has not inflicted any considerable damage.
The director-general of the crisis management department of the province later told Mehr correspondent that the earthquake had no causalities, but damage to buildings and structures is still being investigated.
A spokesperson for Iran's emergency medical services said the number of the injured has reached 36 so far, of which 12 have been hospitalized and the rest received outpatient treatment.
He added that as many as 25 villages near the epicenter of the quake have sustained between 20% and 90% damage.
Recent reports have put the number of injured at 75, with minor injuries.
