PRINCIPAL DIFFERENCES IN THE STRUCTURAL POSITION OF EARTHQUAKE EPICENTERS ON LAND IN THE SOUTHERN MAGADAN REGION AND ON THE SHELF OF THE SEA OF OKHOTSK NEAR MAGADAN

Abstract

This paper presents the results of investigation of the relation between the earthquake epicenters with ruptures distinguished from gravimetric data collected on land in the southern and central Magadan region and on the shelf of the Sea of Okhotsk near Magadan (hereafter, SSO region). Quantitative analysis of the correlation between the indicators of seismic activity in the studied regions and the values characterizing tectonic fragmentation of the Earth’s crust allowed us to distinguish principal differences in the spatial distribution of earthquakes on land and under the sea.
