Research and Application of Geological Hazard Identification Based on D-InSAR Method

Geological hazards are one of the important issues threatening human safety and socio-economic development. In this paper, focusing on the identification and monitoring of geological hazards, the multi-temporal D-InSAR technique is employed as an effective approach. The aim of this study is to conduct research on the identification and monitoring of geological hazard risks based on the multi-temporal D-InSAR technique. Firstly, multi-temporal D-InSAR data is collected and processed to obtain surface deformation information. Then, by analyzing the spatio-temporal characteristics of surface deformation, geological hazard risk points are identified. Finally, the identified hazard points are continuously monitored using the D-InSAR local monitoring technique, and field verification is conducted to promptly confirm the hazards and understand their changes. Experimental results demonstrate that the multi-temporal D-InSAR technique for identifying and monitoring geological hazard risks is accurate and feasible, providing effective support for hazard early warning and risk management. This research is of practical significance for ensuring engineering safety and reducing disaster risks, and it offers valuable references for related research and applications.
