This article examines aspects of the application of geomorphometric methods to the identification of regional-scale lineaments using a digital relief model and a gravity field model in marine areas using the Laptev Sea as an example. The results of lineament analysis showed their applicability for further use in developing a model of earthquake source zones and seismic hazard assessment. The study showed the effectiveness of methods of shadow analysis and identification of keel forms by calculating the curvature of the relief for identifying large seismic lineaments, provided that the results of geomorphometric analysis are used together with data on the distribution of earthquake epicenters. The presented approach to identifying seismic lineaments can be very promising for the development of a lineament-domain-focal model of zones of possible earthquake sources in the vast shelf zones of Russia, for which there is no necessary volume of geological, geophysical and paleoseismological data.
