Abstract
An intermediate-depth earthquake is confirmed at a depth of 158 4 km under the northern foothills of the Greater Caucasus. Separate methods were used to confirm the depth: data from local and regional networks, teleseismic depth phases, and examination of waveforms. Additional examination of global catalogs suggests the presence of a (perhaps remnant) northeast-dipping subduction zone under the Greater Caucasus. The most likely explanation appears to be subduction of oceanic crust with the interface at the northern edge of the Kura Basin. Events at depths of 30 – 50 km in the Kura Basin may be related to underthrusting by the South Caspian basin rather than subduction in the Greater Caucasus.
