| Abstract: | Taking the MS5.4 earthquake in Baicheng County, Aksu District, Xinjiang Uygur Autonomous Region on March 24, 2021 as an example, this study uses UAV to take aerial photos of the disaster area, and completes UAV remote sensing information acquisition and analysis of the surface rupture, building damage and road damage in the disaster area combined with field investigation. The results show that the Baicheng earthquake causes a surface rupture zone with a length of about 5 km, the main rupture zone has the characteristics of sinistral strike slip, which is consistent with the direction of the main compressive stress field; Affected by ground motion, surface rupture, site type, soil composition and other factors, the old brick and wood structure houses around the surface rupture zone are damaged to varying degree, and the rural roads are damaged to varying degree. The distribution of surface rupture and earthquake damage caused by the Baicheng earthquake is controlled by the fault zone. |
