Abstract :
In steep mountainous areas, landslides are a
widespread geological hazard that endangers people's
lives as well as infrastructure and the environment.
Ground deformation measurement has changed as a
result of advancements in monitoring techniques,
notably with regard to InSAR approaches and
conventional to contemporary satellite systems. With its
advantages of high precision and dynamic real-time
monitoring, InSAR makes use of radar interferometry
for economical and wide-ranging coverage. InSAR
technology, has shown promise in tracking risk
scenarios. Operating in TOPS mode, the Sentinel-1
satellite system is selected because to its extensive
coverage, frequent acquisitions (12-day return
intervals), and open data policy.
Based on 47 Sentinel-1A SAR acquisitions from
2021-01-12 to 2022-12-21 for PSI, the study applied PS
technique and found out that the average displacement
in the region to be ranged from -179.46 to 159.64 over
the research duration. Comparing our result with the
stable point on ongoing tunnel project the R square
value was found to be 0.867 with standard error of
0.008.
