The second earthquake was revealed in structures restored and/or built during the Fatimid period (1050–1116 A.D.) ( al-Tarazi and Khorjenkov, 2007), thereby establishing a terminus post quem of 1050–1116 CE. al-Tarazi and Khorjenkov (2007) note that excavator Donald Whitcomb identified a destruction layer associated with this earthquake, which he believed led to the abandonment of Ayla due to its devastation. This destruction was discovered in contexts dating to the Fatimid period (1050–1116 CE).
