In 1138, Aleppo was a large city with tens of thousands of people. Local residents felt that after the forequake activity, they fled to the countryside before the earthquake occurred. However, many people did not take the forequake seriously and decided to stay in Aleppo. This wrong decision caused a large number of casualties. The main earthquake on October 11 caused a large number of buildings in Aleppo to collapse, killing thousands of people. In addition, the earthquake also caused serious casualties and losses in northern Aleppo.

According to historical records at that time, the major earthquake in Aleppo in 1138 caused 230,000 deaths, but modern historians believe that it may be that the number of casualties in this major earthquake and the major earthquake at the junction of Azerbaijan and Georgia on September 30, 1139 [In 1139, the 7.3-magnitude earthquake occurred at the junction of western Azerbaijan and Georgia, causing 230,000 to 300,000 deaths].
