Abstract

Lineaments were identified using LANDSAT-8 satellite images and digital elevation models obtained from the ASTER GDEM satellite over the Chatkal-Kuramin region. Taking into account the stock materials and a comprehensive analysis of the results of processing remote sensing data, a map of lineaments of a 1: 100,000 regmatic network was compiled. Based on the automated visual lineament analysis in the Geomatica PCI program, lineaments of the regmatic network were obtained, which are located in the focal zones of strong earthquakes.

Highlights

The presence of a regmatic network of faults in Central Asia is substantiated in the works of VV Kiselev, VG Korolev [1], OM Borisov [2, 3], D.Kh
The differences in the density of the faults reflected on the maps made it possible to record in detail the block structure of the earth's crust of the Chatkal-Kuramin region, to reveal faults and to identify seismologically important directions of the fault grid and intervals density fields of tectonic disturbance (Fig. 3)
For the territory of Central Asia, it was established that most of the regional deep faults spatially coincide with the lineaments [3,4], in our opinion, in the territory of the Chatkal-Kuramin region

Summary

INTRODUCTION

The presence of a regmatic network of faults in Central Asia is substantiated in the works of VV Kiselev, VG Korolev [1], OM Borisov [2, 3], D.Kh. It was found that a single network of straight-line faults consists of six components, and the angular intervals between the rays vary from 22 to 23 °. In space, their density and completeness of manifestation are different and most often in a particular region a 4 or 6-. In the Chatkalo-Kuramin mountains, for the first time, a regmatic lineament-rupture network based on the interpretation of aerial photographic materials was described by A.K. Glukh [7], who identified six main components (0 °, 20 °, 60 °, 90 °, 310 °, 340 °). The lineaments were deciphered using stock materials and seismological analysis of the studied territories was carried out. Seismic lineament are understood as a strip quasi-linear arrangement of sources of modern and ancient earthquakes of various magnitudes and depths [10, 11]
