Abstract

We investigated the typical subsurface characteristics of some minor faults that may be strongly impacted by the activity of the Cimandiri and Lembang regional faults. The area near these active regional faults is typically rich in fractures and cracks induced by tectonic stress. These fractures and cracks play an important role in groundwater storage and movement. The fractures and cracks surrounding the faults have created high-permeability zones, which facilitate groundwater flow. This study aims to characterize the subsurface conditions in several regions around the Cimandiri-Lembang fault system, particularly in hardrock environments such as paleo-carbonate or volcanic rocks, using 2D resistivity tomography imaging. We present images of the resistivity tomography data that reveal typical geological features and aquifers formed by fractures and cracks influenced by the Cimandiri-Lembang regional faults in West Java. Our findings highlight the significance of tectonic activity in shaping subsurface hydrology, providing critical insights for groundwater management and its potential exploration in fault-affected regions.
