“…This has also been reported by Yahaya et al (2019). The displacement at Paya Terubong can also be related to underground water movement in the zone, as discovered using geophysical measurement (Rauff et al, 2020a). However, the result is not presented in this work since it is not within the scope.…”

Ground deformations (e.g., landslide and subsidence) have substantially risen recently around Penang Island, Malaysia. The development of hillslopes for rapid urbanisation and heavy rainfall has detrimental impacts on Penang Island soil layers. Modelling, simulation, and the development of susceptibility maps were past methods used to predict potential ground deformations of Penang Island. There is no published work on the Interferometry Synthetic Aperture Radar (InSAR) technique, where ground deformation of the region has been holistically studied. This work integrates the Persistent Scatterer InSAR (PS-InSAR) technique with Ground Penetrating Radar (GPR) to monitor the deformation on the island and identify possible subsurface causes for the disturbance. Twenty-four descending Sentinel-1A datasets acquired between 14th July 2017 and 13th October 2018 were processed to monitor and map ground deformation areas with a focus on three selected regions-Batu Feringghi (BF), Paya Terubong (PT), and Tanjung Bungah (TB), where multiple landslides occurred between 2017 and 2018. InSAR results were later analysed using the Statistical Package for the Social Sciences (SPSS) tool and validated by the available Global Positioning System (GPS) analysis. InSAR analyses reveal the mean deformation values of -3.13 mm/yr, -2.76 mm/yr and -4.77 mm/yr for the BF, PT, and TB areas. GPR surveys were conducted with a 300/800 MHz dual-frequency antenna at the three selected study areas. Anomalies (wall cracks, road fissures, cavities, drains, and pipes) detected using GPR profiles correlated well with the permanent scatterer points calculated using the InSAR technique.

ABSTRAKGerakan tanah di kompleks perkantoran Kabupaten Sukabumi di Jajaway, Palabuhanratu, terjadi di luar perkiraan dan perencanaan pembangunan sebelumnya. Untuk melihat kondisi dan luasan daerah gerakan tanah dan dalam usaha mengurangi resiko kerugian lebih besar, diperlukan identifikasi bidang gelincir gerakan tanah di kompleks tersebut. Bidang gelincir dicari berdasarkan model tahanan jenis yang diperoleh dari survei pengukuran geolistrik. Akuisisi data dilakukan pada 7 lintasan, dengan 6 lintasan berarah utara-selatan dan 1 lintasan berarah barat-timur. Metode akusisi yang digunakan adalah tahanan jenis multielektrode dengan konfigurasi dipole-dipole. Hasil penelitian membuktikan bahwa kondisi perlapisan batuan lepas tetapi lebih berat di atas lapisan lempung merupakan salah satu penyebab kejadian pergerakan tanah. Kejadian itu sangat terlokalisir karena kondisi seperti itu tidak ditemukan pada lintasan lainnya.Kata kunci: bidang gelincir, geolistrik, gerakan tanah, konfigurasi dipole-dipole, tahanan jenisABSTRACTGround movement in the Sukabumi Regency office complex (Jajaway, Palabuhanratu), occurred unexpectedly. To reduce the potential risk, we need to identify the slip surface to detect the possibility of more landslides. The resistivity model by the dipole-dipole geoelectrical method was applied to find the slip surface. Data acquisition was carried out in 7 lines: 6 north-south lines and 1 east-west line. The resistivity models present the distribution of resistivity below the surface. Above this clay layer, there is a higher resistivity layer, which is related to sandy tuff and breccia. The condition might cause the previous creeping type of ground movement. The type of layering is not found in the other lines. Therefore we do not expect a similar ground movement would occur in those lines.Keywords: dipole-dipole configuration, geoelectrical, landslide, resistivity, slip surface

“…The study of landslide deformation is mainly divided into the following aspects: the deformation rate of the landslide is analyzed, and the evident deformation zone on the landslide is determined by analyzing time series [6][7][8][9]; the deformation rate of the landslide is monitored and the evolution of phase transition is analyzed [10][11][12]. Previous studies have used InSAR in combination with other technologies to monitor slope deformation, slope hazard characteristics, and potential landslide bodies [13][14][15][16].…”

The conventional method of monitoring the stability and safety of slopes at high-altitude dumps is associated with a high financial investment and poses a risk for personnel involved in the deployment of monitoring instruments. In order to mitigate the challenges posed by conventional monitoring methods, including high investment and potential risks to personnel, we employed Synthetic Aperture Radar Interferometry (InSAR) technology for the evaluation of slope stability at a high-altitude dumps in Sangri County, Shannan, Tibet. The utilization of Synthetic Aperture Radar Differential Interferometry (D-InSAR) technology was employed to observe the deformation of the dumps over the course of the rainy season, spanning from 2019 to 2022. A four-year (Nov 2018 to Oct 2022) deformation rate assessment of the dumps was performed utilizing the Small Baseline Subset⁃Interferometric Synthetic Aperture Radar (SBAS-InSAR) technology. The accuracy of InSAR monitoring in high-altitude slope areas was verified through correction with the results obtained from GNSS RTK monitoring. The state of stability and safety of the slope at the dumps was evaluated based on the results obtained from deformation monitoring. The D-InSAR monitoring results indicated that when the rainfall surpassed 300 mm, the slope deformation of the dumps exhibited a maximum displacement of 20 mm, necessitating intervention. The results of SBAS-InSAR monitoring indicate that the slope of the dumps underwent substantial deformation changes during the rainy season, yet remained stable during the dry periods. However, the results of our SBAS-InSAR monitoring indicate that the deformation and displacement curves of the dumps did not correspond entirely with changes in rainfall, and exhibited a hysteresis phenomenon in terms of deformation magnitude. The application of InSAR technology allows for the comprehensive and dynamic monitoring of the slopes at high-altitude dumps, offering reliable long-term assessments of safety and stability and ensuring secure and stable operations.
