Iranian media reports say an earthquake measuring 5.4 on the Richter scale shook Khoy County in northwestern Iranian Province of West Azerbaijan Wednesday morning while the tremor was also felt in the nearby counties early morning.

Citing Khoy governor Zabihollah Kazemi, IRNA reported on October 5 that although the number of those who had been injured by the quake was large, they were treated soon as their injuries were minor, the governor noted.

Zabihollah Kazemi reportedly went on to say that estimation indicates that the earthquake has damaged 200 housing units but the damages have not been serious.

The quake caused more damages to residential units in the villages, he added.

According to the Seismological Center affiliated to Institute of Geophysics of Tehran University, the early morning quake occurred at 03:51 am local time (0021 GMT).

Further, 20 aftershocks followed the main earthquake just 10 minutes later.
