By 20:00 UTC state run agencies reported that 180 people were killed and 1300 were injured. 6 villages have been almost completely destroyed. 60 villages have sustained 50%-80% damages by earlier reports. The earthquake has cut off the gas supply to 70 villages in the Ahar area.

Labor news agency ILNA reports that Rescue services admitted tonight that 10 to 20 villages in the epicenter area have not been reached yet. The power is down in the earthquake stricken area and as many roads are blocked Search and Rescue work will be very difficult.

Iranian officials have announced that the figures from the death and wounded will increase due to the critical condition of the wounded.

According to the report of Presidential Office website, the Iran cabinet members expressed their deep sorrow over the earthquake incident which has caused so many people to die, and expressed sympathy with victims’ families.  The government called on all natural disaster headquarters and responsible bodies to mobilize all their possibilities and releif equipment and provide quake-stricken areas with all kinds of necessary assistance.

  1. I have been waiting for that for a while now. The HAARP Facilities must have stored up enough Energy in the upper Ionosphere, so it just took a while,but it looks like it is working and they finally achieved directional Control.
    Look out for many more to come,however they will not create a Tsunami as in Japan.
    So it will take much more intensity to produce the intended effects.
