Деформационные изменения земной коры в области повышенных тектонических напряжений

• Статья на elibrary

At present, radio interferometry methods are actively used to determine Earth's surface deformations. The strongest displacements are caused by earthquakes, volcanic eruptions and great landslides. Such tasks require an adequate mathematical model for the stress-strain state of the Earth crust rocks.

The paper presents one of the possible approaches to describe deformation changes in the result of big seismic events. As the Earth crust model the approximation in the form of homogeneous isotropic elastic half-space with a combination of double forces, which correspond to earthquake mechanism, is chosen. The model calculates the area of surface deformations, using maximum shear stress and dilatancy. Numerical modeling of surface deformations of the Earth's crust is carried out for the Japanese earthquake on March 11, 2011. The simulation results are compared with the displacement of the Earth's crust, obtained by radar measurement of ALOS and Envisat satellites.
