This strike-slip event damaged and destroyed a number of small villages in a sparsely populated region near the Alborz mountain range. It left four people dead, forty injured, and about 800 people without homes. The deaths and injuries in this moderate event were attributed to the low quality construction styles that are typical of the area. The Iranian strong motion network provided data by which seismologists determined the type and extent of the slip as well as the peak ground acceleration. Other large and destructive earthquakes have affected the Semnan Province, including several destructive events in 856 AD and 1953. ==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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「2010 Damghan earthquake」の詳細全文を読む スポンサード リンク
