 This paper presents an improved seasonal interferometry stacking in SAR, SI stacking, method for detecting potential landslides in mountainous regions. The study area is the river valley section of the G213 road from Wenchuan County to Mao County in southwest China. The SI stacking method was applied to Sentinel-1 satellite data from 2017 to 2022. The results show that the proposed method is more effective in reducing noise caused by low coherence compared with the conventional stacking in SAR method. The standard deviation of the identified landslides was reduced by 46 percent, 22 percent, 10 percent, and 14 percent for the four tested areas, respectively. This indicates that the proposed method is suitable for detecting potential landslides in mountainous regions. This article was authored by Zhiyuli, Karindai, Jean Dang, and others.
