The earthquake was located in the Zangezur Mountains near the boundary between southwestern Armenia and Azerbaijan's exclave, the Nakhichivan Autonomous Republic. Both territories were part of the Soviet Union at that time.Significant Earthquake Database https://www.ngdc.noaa.gov/nndc/struts/form?t=101650&s=1&d=1 https://web.archive.org/web/20060929000601/http://www.ngdc.noaa.gov/nndc/struts/form?t=101650&s=1&d=1 dead September 29, 2006 National Geophysical Data Center / World Data Service (NGDC/WDS) National Geophysical Data Center, NOAA 10.7289/V5TD9V7K 1972 Data Set Tectonic setting The Pambak-Sevan-Sunik Fault extends in the NW–SE direction. The fault can be traced continuously for 400 km and consists of four major segments. The 1931 Zangezur earthquake was located in the area of the Sunik-Zanghezour segment, which is about 120 km long.Estimating slip rate and recurrence intervals for strong earthquakes along an intracontinental fault: example of the Pambak-Sevan-Sunik fault (Armenia) Hervé Philip Ara Avagyana Arcadi Karakhanian Jean-François Ritz Samira Rebai 2001 Tectonophysics 343 3–4 206–232 10.1016/S0040-1951(01)00258-X 2001Tectp.343..205P The fault was also the source of the magnitude 7.5+ 1139 Ganja earthquake; the largest and most destructive seismic event in the Caucasus.Alice O.
