The earthquake is estimated to have killed around 30,000 people. It was felt over an extensive area, from Sicily to Mesopotamia and Anatolia to upper Egypt, mostly affecting the Ayyubid Sultanate and the Kingdom of Jerusalem. The cities of Tyre, Acre and Nablus were heavily damaged. A magnitude of {{M|s|link=y}} 7.6 has been estimated with damage up to XI on the Mercalli intensity scale. Records of the earthquake A large earthquake or series of earthquakes is described in many written sources during the period 1201–1202 (597–598 AH). It is unclear as to whether they refer to a single mainshock with several large aftershocks or more than one unrelated earthquake. Given the rarity of such large events in this area it has been considered more likely that the reports all refer to the same mainshock.WEB, Significant Earthquake Information, National Geophysical Data Center / World Data Service (NGDC/WDS): NCEI/WDS Global Significant Earthquake Database.

Tsunami The tsunami probably associated with this event was observed in eastern Cyprus and along the Syrian and Lebanese coasts. Casualties Although a figure of 1,100,000 deaths is often quoted for this earthquake, it includes all deaths for the year in question, including those from the famine and subsequent epidemics caused by the failure of the Nile flood that year. A more realistic estimate of 30,000 deaths has been made from the analysis of contemporary records.
