Abstract:
We present a comparative modeling of the zones of relative shear deformation for four Kamchatka earthquakes Mw$\geq$ 4.8 that occurred between December 2018 and March 2021. Modeling based on a static model of the deformation field in the framework of the theory of elasticity. The Earth's crust is considered as a homogeneous isotropic elastic half-space, in which there are different sources of stress describing the source of the earthquake: a point source in the form of a single force, a point source in the form of a combination of nine double forces, a distributed source in the form of a rectangular area.
Keywords:
stress-strain state of the Earth's crust, relative shear deformations, earthquake source model, zones of increased deformations.
