  The earthquake occurred on October 15, 2016 (Ml=5.0) re-attracted attention
to the tectonic activity of Western Black Sea Basin. The focal mechanism
solution of this earthquake indicates reverse faulting, similar to the Bartin
Earthquake of September 3, 1968 (MS=6.6), which is the strongest instrumentally
recorded earthquake along the Turkish margin of Black Sea, and reveals another
seismological evidence for the active thrusting in the region. In this study,
the fault structures that considered to be formed by the effect of
compressional tectonic regime and the structures formed by the activities of
these faults beneath the shelf and slope areas between the region offshore
Akcakoca-Cide at the southern part of the Western Black Sea Basin revealed by
using marine seismic reflection data and the composite well log data. By means
of the geological sections in previous geological studies, the land-offshore
geological sections were prepared and findings about the continuation of the
geological features from land to offshore in the study area were presented.
These geological sections developed for the study area and the geological
features recognized from the seismic migration sections, support the presence
of the N-S directional compressional tectonic regime in Western Black Sea.
