Fault mapping by data of aerospace surveys to ensure the safety main pipelines (by example section Chayvo–De-Kastri oil pipeline). Bulletin Tomsk Polytechnic University. Geo Аssets Engineering, 2023, vol. 334, no. 6, рр.92-102.In Rus. The relevance research is caused need identify hazardous geological processes during construction and operation pipelines. Russian Federation ranks second in world terms total length pipelines, where accidents sometimes occur as result negative impact natural man-made factors. affecting are displacements zones active faults earth's crust. Diagnostics presence fault territory planned linear structures makes it possible potentially dangerous areas that should be paid close attention, organize constant monitoring places movements soil masses. Based on economic considerations, advisable conduct using Earth remote sensing data, use modern geoinformation products processing. Monitoring allows you quickly assess changing engineering conditions pipeline laid, well detect signs occurrence pose danger infrastructure facilities. corridors routes must carried out all available means operation. ArcGIS, QGIS LEFA software combination with geophysical provided Unified Geophysical Service Academy Sciences seismic activity, its intensity nature relationship faults. aim show map most zones, a potential threat Objects: space images corridor route ruptures seismogenic nature, maps earthquake epicenters previously identified near route. Methods: interpretation satellite images, methods modeling, mapping, statistical methods, automated lineament analysis, resolution, size visibility without loss information quality, such interpolation aggregation spatial analysis interdependence earthquakes, compilation geoinformation. Results. geological, about was laid order zones. Automated different spectral ranges resolution made probable activity study area estimated basis data. Potentially sections area, along which presented map, characterized increased activity.
