Detailed study of Earth's crust in Baykal rift zone according to refracted waves data
Abstract
Investigations of the crust and upper mantle by the deep seismic sounding method are carried out in the Baykal rift zone. The principal features of deep structure of the region and the anomalous peculiarities of deep structural that distinguish the rift zone from neighboring inactive regions are described. The study of the intracrustal seismic waveguide is of fundamental importance in predicting earthquakes. An algorithm for the interpretation of refracted waves for two dimensional media containing such a waveguide is presented. The use of the algorithm is illustrated in theoretical models. The results show that the velocity section is characterized by substantial velocity changes in the upper and middle parts of the crust in both vertical and horizontal directions.
