During long-term erosion after a strong earthquake, cracks in the soil, which are traces of cracks, gradually disappear, making it difficult to identify. The rapid development of modern high technology has opened up unexpected new possibilities for the discovery and detailed study of such hidden structures.
Due to the fact that Ulaanbaatar is located in a seismically active region, the seismic resistance assessment of buildings was based on the seismic micro-region maps and active faults used at that time between 2009-2015. There is an urgent need to map new cracks in Ulaanbaatar that have been discussed in recent years, and to use them to redefine the seismic resistance of buildings. In this study, interferometer processing of Sentinel 1 satellite data for active sensing was used to identify new cracks with high spatial accuracy and re-evaluate the seismic resistance of buildings at a distance of 100-500 m.
