Abstract

Taking into account the scale of the Earth and the size of its crust in the ocean zones, the semi-infinite Kirchhoff plates located on a deformable base were taken as lithospheric plates. The oceanic water layer, taking into account the scale, is described by the shallow water equations. Taking into account the tidal fluctuations on the Earth caused by Lunar attraction, the case of contact of lithospheric plates with the base at negligibly small tangential contact stresses and low-frequency harmonic vertical influences is investigated. The described problem is considered in a four-block structure, in each block of which the corresponding boundary value problems are set. Using the block element method, the study is reduced to the study of a system of functional equations that allow identifying the conditions for the occurrence of a starting earthquake. The consequences of the initial earthquake in this setting on the behavior of the liquid layer are investigated. Thanks to this method, it is theoretically shown that tsunami waves can occur in the zone of the epicenter of an earthquake. Currently, there are expanded opportunities for a more in-depth study of the possibility of predicting a tsunami in connection with the creation of a new universal modeling method based on the fractal properties of packed block elements. This approach complements the modeling of lithospheric plates with materials of complex rheology with new capabilities.

Keywords:
