847 Damascus earthquake

[2] There were an estimated 20,000 casualties in Antioch according to the 13th-century historian and writer Al-Dhahabi, and 50,000 in Mosul.

[2][4] A number of other towns and cities in the Middle East also suffered major destruction in 847 A.D., probably on the same day (24 November).

The Damascus earthquake began around dawn, lasting until at least midday; part of the Umayyad (Great) Mosque was destroyed and its minaret fell down.

[5] There was destruction in towns in Homs (Syria), in Lebanon, and also in the region of the Jazira (Upper Mesopotamia).

[6] Similar records exist in the western Mediterranean too and Rome was hit by a heavy earthquake that year causing a landslide on the Capitoline Hill.
