Distribution of epicentres of earthquakes and structure of the Earth’s crust in the south east flank of the Chersky seismic belt (the north east of Russia)
In the paper, the results of quantitative analysis of the relationship between seismicity and deep structure of the Earth’s crust are presented. The majority of earthquakes are confined to the areas with higher horizontal gradients of the depth to the base of granite and sedimentary layers. Also, the majority of earthquakes are located in areas with great thickness of granite and minimum thickness of sedimentary layer.
