【 摘 要 】

We computed seismotectonic deformations (STD) of earth crust in Pamir and neighbor areas. We used ISC (International Seismological Centre, London) catalogue for average STD rate computations, including more than 25000 earthquakes that took place between 1934 and 2016. STD tensor axes' directions were computed based on hypocenter focal mechanisms of 3049 earthquakes that took place between 1946 and 2018. We haveplotted maps showing distribution of STD intensity and number of earthquakes for various ranges of hypocenters depths, and map showing horizontal part of STD tensor. Finally we analyzed different deformation conditions in South Tien-Shan and Pamir.
