A recent tectonic structure of the Kurai Ridge has been revealed by a detai
led geomorphological study of its central part (large-scale mapping based o
n study of aerospace survey materials and field investigations). This struc
ture is a system of faults radiating in a fan-like manner in the vertical s
ection and subparallel in plan. Tectonic movement along these faults forms
a step-like protrusion wedge. The present-day tectonic activity of the terr
itory manifests itself as seismically induced landslides and zones of small
faults shifting the steep sides of Late Pleistocene glacier valleys.
