| Abstract |
Mount Sinabung had been dormant for 400 years, but it erupted again in 2010 and has become active since.The objective of this research was to monitor and to analyze monthly vertical ground deformation around Sinabungvolcano from 2021 to the end of 2022, and to produce time-series maps of the area to detect deformation trends.This research utilized remote sensing technology and geographical information system (GIS), specifically, Sentinel1 data and Differential Interferometric Synthetic Aperture Radar (DInSAR) technique. Results of this researchshowed significant movement of the ground surface and changes in spatial distribution of the volcano area. Someareas deflated, while others inflated. The observed deformation statistics fluctuated from months to months with nosignificant pattern. The results showed that most of the area around the volcano has been inflated (4,098.33 Ha).The range of deformation measured was between -0.010 to +0.099 meters, with the average of +0.055 meter. InMarch 2021, there were a total of 13 explosive eruptions, producing ash cloud as high as 5,000 m. Incidentally,inflations of about 0.038 m were observed around the volcano a couple months prior. There were 26 eruptions inApril 2021, with the biggest eruption produced ash cloud of 1600 m. From April to August 2021, the deformationranged around -0.01 to 0.01 meters. After another eruption in August 2021 with ash cloud height of 4,500 m, thedeformation was continued to experienced inflation of about 0.038 m. There was a drastic inflation in October whichreached 0.033 m, then deflate dramatically to -0.037 m in November 2022. This indicated tectonic activity aroundthe volcano, which was caused by continuous changes in magma pressure underneath, signifying that the volcanois still very active. |
