Depth Faults Along The Regmatic Network Of The Chatkalo-Kuramin Region And Their Relationship With Seismicity

Аннотация

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.

The stability of the strike allowed V.S.Burtman to The presence of a regmatic network of faults call it stationary [5]. in Central Asia is substantiated in the works of VV Kiselev, VG Korolev [1], OM Borisov [2, 3], In the Chatkalo-Kuramin mountains, for the D.Kh. Yakubov and others [4], V. S. Burmana first time, a regmatic lineament-rupture [5], L. M. Rassvetaeva and others [6]. It was network based on the interpretation of aerial found that a single network of straight-line photographic materials was described by A.K. faults consists of six components, and the Glukh [7], who identified six main components angular intervals between the rays vary from (0 °, 20 °, 60 °, 90 °, 310 °, 340 °) 22 to 23 °. However, in space, their density and In the analysis and interpretation of space completeness of manifestation are different images, decoding of linear structures or and most often in a particular region a 4 or 6- The US A Journals Volume 02 Issue 12-2020 68 The American Journal of Applied Sciences IMPACT FACTOR (ISSN – 2689-0992) 2020: 5. 276 Published: December 27, 2020 | Pages: 68-76 Doi: https://doi.org/10.37547/tajas/Volume02Issue12-11 OCLC - 1121105553 lineament is used. For the first time this term In the morphological appearance of the was used in 1904 by the American Chatkal-Kuramin region, the features of geomorphologist Hobbs [8]. According to connections between the relief and structures which, at present, lineament is understood as are clearly expressed. The ubiquitous nature any rectilinear change in the relief of the of the manifestation of the latest tectonic earth's surface, landscape and geographical movements determines the features of the objects. Ya.G. Kats et al. Noted that in modern relief. accordance with the initial materials of This work was carried out on the basis of the interpretation, lineaments in the seismic field - use of automated lineament analysis in the seismic lineaments - can be distinguished [9]. Geomatica PCI program, which makes it Deciphering linear structures in seismic zoning possible to obtain linear structures. is used in a number of areas of earth science. In order to identify lineaments, an automated Based on this, the lineaments were interpretation of the data of digital elevation deciphered using stock materials and models obtained from the ASTER GDEM seismological analysis of the studied satellite was carried out and, taking into territories was carried out. account the stock materials, maps of Seismic lineament are understood as a strip lineaments of 1: 100,000 scale were compiled quasi-linear arrangement of sources of (Fig. 1). modern and ancient earthquakes of various magnitudes and depths [10, 11]. RESEARCH METHODOLOGY The object of research is a mountain structure, united by the name of the Chatkalo-Kuramin region and located in the Middle Tien Shan.
