Abstract
This article describes the impact of changes of the Earth’s crust deep temperatures in a seismically active region of the Northern Tien-Shan on the formation of thermal deformations in earthquake focal zones. The research method is based on numerical modelling of temperatures using data of seismic velocity up to a depth of 100 km and experimental dependencies of thermal parameters: heat flow, thermal conductivity, radiogenic heat generation. Comparative analysis of the geothermal model parameters and distribution of earthquakes in the area has been performed. The crucial factor influencing the formation of critical deformations is the existence of high-temperature areas with excessive temperatures 100 ÷ 250 ℃ above solidus at depths of 20 ÷ 45 km. The distribution of earthquake hypocenters is controlled by the values of thermoelastic stresses with an isobaric border of 0.35 GPa and anomalous temperature values over the isotherm of 230 ℃.
