Seismic activity along fault systems in the Levant produced what may have been a series of earthquakes between 747 and 749, later recorded as a single event due to differing calendrical systems used across the Umayyad Caliphate. A more southerly initial quake appears to have weakened structures across the region, making subsequent shocks more destructive.
On January 18, 749, a catastrophic earthquake struck with its epicenter in Galilee, within the Umayyad Caliphate. The areas most severely affected lay west and east of the Jordan River. Cities including Tiberias, Beit She'an, Pella, Gadara, and Hippos were largely destroyed, while numerous other urban centers across the broader Levant sustained heavy damage.
The earthquake killed tens of thousands of people and devastated the urban fabric of the Jordan River valley and surrounding Levantine regions. The destruction of multiple major cities disrupted settlement patterns and left lasting archaeological evidence of sudden abandonment, shaping scholarly understanding of mid-eighth-century population decline in the region.
