Abstract

—Seismic-moment tensor solutions for earthquakes in Azerbaijan for 2012–2015 have been calculated with a new method by full waveform inversion of broadband data from modern digital seismic stations and processed statistically. The results are used to model main faulting elements in the region, to correlate the seismicity and fault patterns, and to compile a map of fault plane orientations for large events. The principal compression stress (P) directions are NW to SE in the Zaqatala area and N–S in the Sheki area but then gradually change clockwise toward NE–SW in the Caspian Sea. The directions of principal extension are mainly NE–SW and N–S within the zone where the Kura basin is subsiding beneath the Great Caucasus.
