The geological area where the earthquake occurred is characterized by many faults trending northeast and east–northeast. The predominant rock types are volcanics which lie on top of severely deformed ophiolites. Its epicenter is located within the Gullu and Allahuekber Mountains which represents a Quaternary shear zone with left-lateral faults marking the boundary. Seismicity is also associated with the Abul Samsar Fracture Zone; a northeast–southwest trending feature of the Caucasus Mountains. A 15 km surface rupture trending north–northeast was observed, exhibiting left-lateral and normal slip. Graben-type ground fractures also occurred due to extensional mechanism. The surface rupture length was not consistent with those expected for the earthquake's magnitude.Erdik Mustafa Report on the Turkish Earthquake of October 30, 1983 Earthquake Spectra 1984 1 1 151–172 10.1193/1.1585261 1984EarSp...1..151E 109507734 https://journals.sagepub.com/doi/pdf/10.1193/1.1585261 subscription Damage Well-constructed stone, concrete block and masonry infrastructures such as schools, mosques and medical facilities had less damage compared to others in the affected villages. Some remained intact even in the meizoseismal area. The maximum assigned MSK 64 intensity based on damage was VIII. left|thumb|Broken mill in 1984 after the 1983 earthquake in Dönertaş, Horason, Erzurum province Severe damage occurred in the villages of Horasan, Pasinler and Narman municipalities, Erzurum Province. Villages in Sarikamis, Kars Province were also affected. Total destruction was observed in an elliptical area with axes 10 km (major) and 5 km (minor), respectively. The major axis trends northeast. About 80 percent of the at least 1,330 fatilities occurred in this area; 1,332 people were injured. Ten thousand homes were damaged; 3,200 collapsed. An estimated 26,000 livestock were killed.
