Qumis (Damghan) Earthquake of 22 December 856, Mw=7.9<\/strong><\/p>\n

The\u00a0856 Damghan earthquake\u00a0or the\u00a0856 Qumis earthquake\u00a0occurred on 22 December, 856 AD (242 A.H.) with an estimated\u00a0magnitude\u00a0of Ms=7.9. The\u00a0meizoseismal area\u00a0(area of maximum damage) extended for about 350 kilometers along the southern edge of the eastern\u00a0Alborz\u00a0mountains of present-day\u00a0Iran\u00a0including parts of\u00a0Tabaristan\u00a0and\u00a0Gorgan. The earthquake’s\u00a0epicenter\u00a0is estimated to be close to the city of Damghan with coordination of 36.2\u00b0N and 54.3\u00b0E, which was then the capital of the Persian province of Qumis. The total death toll for the earthquake is reported as 200,000, with 45,096 casualties in Damghan alone. It caused approximately 200,000 deaths and is listed by the USGS\u00a0as the sixth deadliest earthquake in\u00a0recorded history. Aftershocks affected the area for several years, probably including a damaging earthquake in western\u00a0Khurasan. The area of significant damage extended along the Alborz for about 350 kilometres, including the towns of\u00a0Ahevanu,\u00a0Astan,\u00a0Tash,\u00a0Bastam\u00a0and\u00a0Shahrud, with almost all the villages in the area severely damaged.\u00a0Hecatompylos, now called \u0160ahr-e Qumis, the former capital of\u00a0Parthia, was destroyed. Half of Damghan and a third of the town of Bustam were also destroyed. The earthquake badly affected water supplies in the Qumis area, partly due to springs and\u00a0qanats\u00a0drying up, but also because of landslides damming streams.
