摘要

According to the World Ocean Program,in the northeastern part of the continental slope of the Black Sea,a set of geothermal,seismological,and seismic studies was carried out.An analysis of the heat flow distribution allowed us to distinguish a negative geothermal anomaly near the Dzhubga area,where the Russia-Turkey pipeline was being constructed.During the seismological observations (August-September 1999,September 2001),more than 1200 seismic events were recorded.They prove the high tectonic activity of the region under study,which stimulates gravitational sediment transport on the continental slope.The seismoacoustic survey carried out in the area of the geothermal anomaly revealed no reflecting horizons within the sedimentary cover.This may be related to the turbidite-landsliding processes.The results of the modeling of the heat flow anomaly show that it originated approximately 1000 years ago due to a powerful landslide.This also suggests the possibility of an avalanche displacement of sedimentary masses in the area of the pipeline at present.
