The National Disaster Management Agency (BNPB) stated that the number of earthquakes that occurred in Indonesian territory during 2018 was 11,418. Nearly 95 percent of earthquakes occur in fault areas and plate boundaries. The methodology of this study has four main stages of data processing, namely the differential interferogram stack stage and coregistered stack formation using SNAP software. The results of the study concluded that the average deformation along the Lembang Fault was 2,485 mm, with a graph that tended to rise. The area most affected by deformation is Cisarua District, with a Line-of-Sight deformation speed of 28.4 -- 48.9 mm/year. The most minor deformation occurred in Lembang Regency with a Line-of-Sight deformation speed of -2.3 -- 19.2 mm/year. Conclusion The PS-InSAR method has proven to be effective in mapping the speed of Line-Of-Sight (LOS) deformation along the fault path. PSInSAR data shows that deformation in the Lembang Fault ranges from an average of 2,485 mm, with an increasing trend from January 2018 to March 2019. The area most often affected by deformation is Cisarua District, West Bandung Regency, with the LOS deformation rate reaching 28.4 to 48.9 mm per year. [ABSTRACT FROM AUTHOR] |
