Ibn al-Athir appears to have written about the same earthquake twice, assigning it two different dates—thus creating a duplicate account. Both dates, however, are incorrect. When the two descriptions are combined, they provide a coherent picture of damage extending across Egypt, the Jazira, and especially Syria, which appears to have been the most severely affected region. Ibn al-Athir reported the destruction of houses in Damascus, Hims, and Hamat, and that a village near Busra was “swallowed up.” He also described widespread devastation along the Syrian coast, including destruction at Acre and Tyre, where “the walls were destroyed,” as well as at Nablus and Tripoli. In contrast, he wrote that damage in Iraq was slight and that no homes were destroyed. The earthquake was said to have been felt as far away as Mosul, Sicily, Byzantium, and Cyprus. Since Ibn al-Athir was residing in Mosul when the earthquake occurred, his observation that damage in Iraq was minimal and that no buildings collapsed is probably accurate and should be given particular weight relative to other sources.
