Imaging Fault Gouge Zones along the Menanga Fault using Integrated Electrical Resistivity and Multi-frequency Ground Penetrating Radar in Pesawaran, Lampung, Indonesia
Detecting fault gouge zones in poorly exposed fault systems is critical for understanding active deformation. The Menanga fault in Pesawaran (Lampung) revealed its activity during the 2021 swarm earthquake near Mt. Ratai at 1.5-4.5 km depth. Due to the limited exposure of the fault plane, geophysical imaging is applied...
