In the cited article, Ambraseys, N. (2004), "The 12th century seismic paroxysm in the Middle East: a historical perspective" (PDF), Annals of Geophysics, 47 (2–3), Istituto Nazionale Geofisica e Vulcanologia: 743, Ambraseys states that the 30 September 1139 quake was in Ganjak, rather than Ganja. He makes no statement about the epicenter of the 11 October 1138 quake, which others place at Ganja. The current state of this article seems to conflate the two, just as Ambraseys suggests in detail is the problem with many of the sources. The more damaging of the two seems to have been the 11 October 1138 quake. It may be better to reassess what needs to be covered in this article, and what the best title should be. Should it cover the period from the November 1137 quake on the Jazira plain through the 30 September 1139 quake? Or should it just be the 11 October 1138 quake or the 30 September 1139 quake, with separate article(s) about the other(s). -- Bejnar ( talk) 16:23, 4 December 2023 (UTC) reply

Ambraseys goes on to say "In fact these losses were due to the earthquake in Ganjak in Georgia." There are three Ganjaks in Iran according to the dab page that you linked to. All three of those are in southernmost Iran, unlikely to be confused by Ambraseys with a place in Georgia. Ganja is in Azerbaijan, not Georgia, but it was occupied immediately after the earthquake by Georgian forces under Demetrius I of Georgia, although he only held it for a few years. Ganjak redirects to Ganja, as it appears to be an Armenian spelling for the place. I don't think that there's an issue here, but maybe I've missed something.
