Creating a fault map of the Central-Kamushovy meganticlinorium of the Western Sakhalin mountains by space survey data

The network of fault zones caused by vertical and horizontal tectonic displacements blocks Earth’s crust relative to each other is clearly visible on the surface in images obtained from satellite surveys. Many researchers distinguish linear annular structures among faults. Lineaments are detected as rectilinear objects with a certain spectral brightness. initial data for experimental research includes Landsat-8 SRTM data. lineament analysis Central-Kamyshovy meganticlinorium West Sakhalin Mountains was carried out using functionality LEFA software package developed decryption technology. results were processed QGIS program tools. Statistical processing lineaments basis researching distribution directions segments set vector strokes map disjunctive disturbances Western scale 1:500 000 compiled obtained. model help toolkit made it possible identify where discontinuous located. As result analysis, many faults rank below 2 identified. Fault mapped 000. It revealed that 15.3 % all earthquakes this area timed Krasnopolsky fault, including zone within 1 km fault—70 %, 1–2 km—19 2–3 km—9 more than 3 km—2 %. work will be useful choosing places construction industrial facilities, well seismic zoning territory.
