The 2010 Damghan earthquake (also known as the Kuh-Zar earthquake) occurred in northern Iran at 11:53:49 local time on August 27 with a
Tectonic setting
The tectonics of Iran are dominated by the continental collision of the Arabian and Eurasian Plates. The rate of convergence has been estimated at two centimeters per year for the past 10 million years; about half of that occurs across the Zagros fold and thrust belt. The northern Iran region near the Alborz mountains contains numerous reverse and left-lateral strike-slip faults that lie to the south of the Caspian Sea. The Astaneh strike-slip fault was a likely source of the 856 Damghan earthquake that caused the largest loss of life in the history of Iran—more than 200,000 deaths.[2] A more recent damaging event that also occurred near the Alborz mountain range was the 1953 Torud earthquake, in which more than 900 perished.[3]
Earthquake
Similar to the 1953 Torud earthquake, the 2010 Damghan event took place in a rural area that exposed relatively few villages to strong shaking.
Damage
The affected area has a low population density and has an abundance of homes that are constructed with local clay material by unskilled workers. The unreinforced stone masonry or adobe homes are sometimes overloaded single story structures with flat wooden roofs with steel beams. Most of these types of homes suffered partial collapse and led to a number of roof collapses. Fifty homes were destroyed, 300 were damaged, including a roof cave-in that left two women dead.[5] Overall, seven villages sustained damage and twelve were destroyed. Four people died, 40 were injured, and 800 were left homeless, but no major infrastructure (dams, bridges, or power stations) were impacted.[7]

Aftermath
Seventy rescue personnel and ambulances arrived at Kuh Zar. People with minor injuries were treated by paramedics and discharged; others were taken to Damghan Hospital.[8] Interior Minister, Mostafa Mohammad-Najjar, along with other government officials and members of the Iranian Red Crescent Society (IRCS), visited Kuh Zar the following day.[9] A temporary camp with 50 tents was established in the village. Food, beds and other necessary items were supplied to the village by the IRCS.[8]
