Studies have been conducted to identify the occurrence of subsidence, a decline of groundwater, and to model the causes of subsidence in areas of Jakarta based on response of microgravity anomaly and vertical gravity gradient over time. Based on the processing and interpretation of gravity data advance of the time concluded that by using a combination of time lapse microgravity and its vertical gradient have been able to localize the source of the gravity anomaly and the results are strongly support the results of filtering to separate the source of the anomaly. The subsidence that occurs predominantly due to resettlement (in West and North Jakarta), caused by the extraction of groundwater and resettlement (in Central and East Jakarta), and dominated due to the extraction of groundwater (in South Jakarta).Keywords : Groundwater, time lapse micogravity, time lapse vertical gradient, resettlement, subsidence

This research aimed to identify the presence of faults in Taman Ayu Village, Gerung District, West Lombok Regency by mapping the magnetic field. The fault outcrops found near this location becomes the reason to suspected the fault existence that reaching residents, farming area and access roads, so it is necessary to study the type, depth and direction of the fault. Measurements were made on 11 lines with a length of each line is 3 km. Each line of measurement is 300 m apart from each other and the distance between measurement points is 50 m, 100 m, and 200 m depending on the distance from the target location. Separation between regional anomalies and residual anomalies using the upward continuation method at an altitude of 1000 m. Qualitative interpretation of residual anomalies results in low anomalies with values from -890.9 nT to 897.3 nT. Quantitative interpretation of the five cross sections by the inverse modeling method with Oasis Montaj 6.4.2 software resulting subsurface geological structures in the form of normal fault. This normal fault is at a depth of 30 m to 480 m which is composed of layers of silt, sandy silt, sand, clay and breccia. The fault passes through Gapuk Village, Taman Ayu and Kebon Ayu and passes through the highway in Northeast – Southwest direction

Based on the BMKG report on Wednesday, July 29, 2018, at 05.47 WIB, an earthquake with a magnitude of 6.4 SR occurred at the epicenter at a depth of 24 km and was 47 km northeast of the island of Lombok. They are allegedly originating from the Back Arc Thrust Flores, the interaction between the Indo-Australian Plate and the Eurasian plate. This study aims to analyze the subsurface structure of the island of Sumbawa and Flores sea based on the distribution of density values. The analysis was carried out by modeling the subsurface structure based on regional gravity field anomaly data. The data used is secondary data downloaded from the topex.ucsd.edu page 18,400 measuring points. Data processing consists of data correction, separation of anomalies, determination of the Second Vertical Derivative (SVD) value, and 3D and 2D inversion modeling. The data corrections performed are Bouguer correction and terrain correction to produce the total gravity anomaly value. Upward continuation is used to separate regional anomalies and residual anomalies. Analysis of the Second Vertical Derivative (SVD) value was carried out to identify rock contact positions and fault structures. The 3D inversion modeling is done by making a mesh model, and to get a 2D cross-section, six slices are used in the 3D model. The results of the 3D model and 2D cross-section, namely the island of Sumbawa to the Back Arc Thrust zone of Flores, consists of 3 main layers comprised of the upper crust with a density of 2.29 gr/cc - 2.63 gr/cc, the middle crust with a density of 2.64 gr/cc - 2.90 gr/cc, and the lower crust with a density of 2.91 gr/cc - 3.14 gr/cc, and based on the model and SVD value, it shows that the Flores back fault, the reverse fault type, starts at a depth of ± 26 km

An earthquake disaster is an event that causes various damage and loss of life. This study aims to determine the vulnerability of earthquake hazards in Bengkaung Village, West Lombok Regency. The method used in this research is the geomagnetic method. The results of this: study indicates the value of the magnetic field anomaly in the range of -1100 nT-1500 nT. 2D modeling with 4 paths shows that the study area is dominated by 5 rock layers with a susceptibility range between (0.013 - 6.21)×10^(-3) in SI, which consists of sandstone, clay, fractured andesite lava, fresh andesite lava. and granite. The highest vulnerability to earthquake hazards is in the southern part of Bengkaung Village, due to the presence of a cohesive soil type (like clay) on the surface of the study area, coupled with the presence of intrusions and faults. Meanwhile, the western part of Bengkaung Village and the northern part of the Bengkaung area have a relatively smaller earthquake hazard vulnerability than the southern part. This is because the western and northern parts have the main layer of non-cohesive soil (sandstone) which has high shear strength and becomes a damper in wave propagation when an earthquake occurs

Ancaman kerusakan bangunan dan infrasruktur lainnya disebabkan oleh adanya zona lemah di bawah permukaan yang dapat menyebabkan bencana alam, seperti likuifaksi, khususnya di pesisir pantai, yang dicirikan memiliki muka air tanah dangkal, tingkat kepadatan lapisan tanah sangat lepas dan geologi daerah terdiri dari batu pasir dan endapan aluvium. Penelitian ini bertujuan untuk menentukan nilai hambatan jenis (resistivitas) dan hambatan konus dari zona lemah di Desa Sekotong Barat, Kecamatan Sekotong Kabupaten Lombok Barat dan bagaimana hubungan empiris nilai resistivitas dengan hambatan konus. Penelitian ini dilakukan menggunakan metode geolistrik konfigurasi Wenner dengan jumlah 6 lintasan dan panjang setiap lintasan 200 meter dan juga menggunakan uji sondir pada 3 titik. Berdasarkan hasil interpretasi data diperoleh litologi batuan di daerah penelitian terdiri dari lapisan pasir jenuh air, lempung lanauan, lempung pasiran dan pasir padat. Hasil inversi data geolistrik menunjukkan keberadaan zona lemah membentang pada seluruh daerah penelitian kecuali pada lintasan 3 dan lintasan 4 yang ditafsirkan tidak berbahaya bagi bangunan diatasnya karena tersusun oleh zona kuat. Diperoleh zona lemah dengan nilai resistivitas kurang dari 10 yang diidentifikasi sebagai lapisan pasir jenuh air dan lempung lanauan dan dibuktikan pula dengan hasil uji sondir memiliki nilai hambatan konus kurang dari 20 kg/cm2. Resistivitas dan hambatan konus berbanding lurus dan hubungan empiris yang dihasilkan berupa grafik polinomial orde tiga dengan koefisien determinasi.0,804

Gravity Data analyses in Lampung area are carried out to identify potential hydrocarbon sub-basins. The hydrocarbon potential in the Lampung sub-basin is indicated by the presence of hydrocarbon seepage found in Wai Imus, Wai Tahmi, and from oil shown in Ratu-1 and Tujo-1 exploration wells. Spectrum analysis, filtering, gradient, and gravity anomaly modeling determine the presence of potential hydrocarbon sub-basins in the Lampung sub-basin. Our results show that the Bouguer anomaly in the Lampung sub-basin ranges from 0 mGal to 90 mGal. A high anomaly appears in the southern part associated with basement high and a low anomaly in the center area of the western region related to the existence of the large Sumatra fault zone. The Bouguer Anomaly spectrum analysis result shows that basement depth in the Lampung sub-basin is 2400 m to 4400 meters deep. Data analysis of residual Bouguer anomaly, SVD residual Bouguer anomaly, and fault structure identified 18 sub- hydrocarbon potential basins scattered in Way Kanan, Tulang Bawang Barat, Menggala, Mesuji, Terbanggi Besar - Seputih Surabaya (Central Lampung), Sukadana and Labuhan Maringgai (East Lampung) areas. Some volcanic paths were also identified from Ratu-1 well, and Tujo-1 well in the Lampung WKP block. 2.5D modeling results of residual Bouguer anomaly show Kasai, Muara Enim, and Air Benakat, respectively, overburdened rock formations deposited from the top, followed by the Gumai Formation, which acts as a seal formation, while the hydrocarbon reservoirs are from the Baturaja and Talang Akar Formation. Our subsurface depth model has been verified by Ratu-1 and Tujo-1 exploration well.
