This study presents an enhanced approach for subsurface investigation using Electrical Resistivity Tomography (ERT) coupled with precise positioning tools, focusing on the Rongga Landslide in Indonesia. ERT is widely recognized its ability to map conditions by detecting resistivity contrasts associated geological structures and water content, especially landslide-prone areas. The combines GPS digital waterpass altimeter improve precision of anomaly detection. Important information regarding...

<title>Abstract</title> This study integrates geoelectrical resistivity inversion, geostatistical analysis, and clustering techniques to improve subsurface characterization in Cikole, Lembang, West Bandung Regency. The primary objective is enhance resistivity-based zonation for groundwater exploration by employing a dipole-dipole array with 10-meter electrode spacing, followed 2D inversion visualize distributions. Geostatistical interpolation using Kriging effectively captures spatial...

In recent years, dozen low-intensity earthquakes occurred in southern Garut, West Java Indonesia; two of them were reported destructive. However, those shallow earthquake clusters are hardly associated with well-known active faults the area. Hence, we conducted 3D gravity combined 2D magnetotellurics (MT) inversions to study subsurface. Gravity and MT modeling confirm a basin around 5 km depth consisting subbasins separated by NE-SW trending local-high ridge. The local high coincides...

Abstract The morphology of the Karangsambung area shows a unique form, namely amphitheater. This results from complexity tectonic, erosion, and depositional processes. active tectonics in this region greatly influence drainage system geomorphic expression. study provides evidence subduction Java. It is an ideal natural laboratory for studying tectonic activity due to Indo-Australian plate with Eurasian during Cretaceous period. We evaluated using DEM assess characteristics index. obtained...

Small islands are often promoted as a tourism destination in spite of the limited fresh water resources availability that they could retain for daily needs. In this context, efforts to provide sustainable small island necessary support purpose. This study aims estimate carrying capacity Pari Island. The estimation method is ratio between and its demand by calculating size, aquifer thickness, annual rainfall, hydraulic conductivity or soil permeability, application rainwater harvesting...

DOI: 10.17014/ijog.4.1.39-47The characteristic of Cimandiri Fault Zone has not been completely defined despite plenty studies had already accomplished. Therefore, an audio-magnetotelluric modeling was carried out. An audiomagnetotelluric survey conducted at two parallel lines (N166oE) that intersected in Cibeber area, Cianjur. The distance between those 4.5 km and each line consisted twenty-one stations with the 500 m. From acquired forty-two apparent resistivity curves, inversion executed...

A detailed study had been conducted on the sediment of Mount Samalas’ volcanic eruption in 1257 AD. Using framework reconstruction ancient Samalas, first step was to map and analyze deposits sediment. Secondly, we analyzed effect geomorphology distance function isopach thickness. The results show that a combination methods allowed provide high resolution distribution thickness deposits, both slope alluvial areas. Geo-electric survey (both Vertical Electric Sound (VES) 2D mapping) consistent...

Abstract The 1257 CE eruption of Samalas volcano, Indonesia, buried the entire island Lombok beneath various thicknesses pyroclastic material during this Volcanic Explosivity Index (VEI) 7 event. This study aims to reconstruct paleo‐topography western before in and analyse sedimentation processes that led its landscape evolution over last 700 years. Stratigraphic data were collected from surveys, such as outcrops, coring, drilling, hand auger wells observation. Electrical resistivity...

Abstract An ENE‐WSW‐trending localized basalt‐diabase outcrop along the SE margin of Luk Ulo Mélange Complex has been suggested as intrusive rocks cut through Paleogene Totogan and Karangsambung formations. However, absolute dating volcanics is older than inferred relative age sedimentary formations, hence in‐situ intrusion theory less likely. A subsurface imaging should delineate possibility nature volcanic rock by looking at continuation to depth. In this study, we did a electrical...

The Guci and Kalipedes hot springs, in northwestern slope of Mount Slamet, Central Java appears on the contact between volcanic breccia rocks with lava  flows. springs is located a structure lineament or fault, west-east trending for Northwest-Southeast direction springs. Baturaden at southeast Mt. Slamet appear polimicbreccia relatively northwest-southeast river valley. Breccia generally have higher permeability compare to impermeable flows. Volcanic study area composed by olivine basalt,...

Abstract The subducting Indo-Australian plate along the Sunda Arc has various degrees of roughness near trench. variation in subducted plate’s seafloor morphology should affect upper dynamic at forearc region and further land, which would appear form seismicity arc. In this paper, we explored pattern topography gravity two regions. First is northern Sumatra, where some ridges have been subducted. second east Java, part oceanic plateau Roo Rise addition, also examined those elongated was...
