991 Damascus earthquake

The 991 Damascus earthquake took place in the city of Damascus on 5 April, 991.
According to historian George Elmacin, the earthquake caused the fall of 1000 houses in Damascus itself, and many people were trapped in their ruins and died. The village of Beglabec was reportedly engulfed due to the earthquake.
According to Elmacin, aftershocks continued until 3 May, 991.
The geophysicist August Heinrich Sieberg estimated that this earthquake caused a "seismic sea wave" which flooded the coasts of the region of Syria. Sieberg did not name a primary source for his estimation.
The historians Pierre Vattier and Marcello Bonito mention the earthquake, but not the tsunami.
