The 847 Damascus earthquake occurred in AD 847. Recent scholarship suggests that the earthquake was part of a multiple earthquake stretching from Damascus to the south, to Antioch in the north and to Mosul in the east. There were an estimated 20,000 casualties in Antioch according to the 13th-century historian and writer Al-Dhahabi, and 50,000 in Mosul. It is thought to be one of the most powerful earthquakes along the Dead Sea Transform.
