a Major geological and structural variations with GPS vectors (blue arrows with average values in mm/yr71). IAESA İzmir-Ankara-Erzincan-Sevan-Akera suture zones. Triangles in (a) and (d) are Holocene and Pleistocene volcanoes (Ks Kısır, Ap Arpacay, Ak Akhuryan, Sms Samsari, Ar Ağrı, Arg Aragats, Gh Gegham, Elb Elbrus, Kzb Kazbek, Ke Keli72). The red rectangular shows the modeled area. b Faults, a fold-thrust system with earthquake distributions (global database between 1960 and 2024; http://www.geomapapp.org73).
