Ibn al-Qalanisi documented shaking in Damascus on the 11th, 14th, 24th, 26th, and 28th of October 1138 CE and stated that travellers and reliable witnesses have described these shocks in the north [of Syria], with the strongest shocks in Aleppo and the surrounding area. In Aleppo, a large number of houses were said to have collapsed, with damage to the city walls and cracks in the citadel. The populace reportedly left their homes and departed from the city—presumably sleeping outdoors due to continuing aftershocks. Ibn al-Qalanisi also records that eyewitnesses described between 80 and 100 shocks, presumably in Aleppo. He further reported that on the night of Friday, 15 October 1138 CE, there was a strong earthquake in Syria, and that in the early hours of Wednesday, 21 June 1139 CE, there were some terrifying shocks, presumably felt in Damascus, which struck men’s hearts with fear.
