Ambraseys (2004:743) notes that 15th century author Ibn Taghribirdi conflates the 1138 CE Aleppo Quakes with the large event of 30 September 1139 in Ganjak while adding that Ibn Taghribirdi reports a loss of 230000 lives in the [1138 CE Aleppo] earthquake when in fact these losses were due to the earthquake in Ganjak in Georgia.

Guidoboni et al. (2004:112-113) discussed earthquakes which followed the 1138 CE Aleppo Quake:

These earthquakes in 1138–1139 were followed by at least four that affected south-eastern Turkey (the historic Cilicia) very little of which is known, all recalled by Michael the Syrian, as a primary source; they had taken place:

1. in September or October 1140, probably causing light damage [JW:This may have actually been on ~29 Oct. 1139 CE - See Michael the Syrian in textual Evidence]
2. in June 1141: the small coastal town of Kalinag, in Cilicia, not well located today, suffered damage
3. in May 1145
4. on 29 December 1149

These were probably earthquakes that were mostly non-destructive but very well felt, so much so as to be mentioned in the texts of the day (see Guidoboni and Comastri, 2003)
