Shallow anatomy of hydrothermal systems controlled by the Liquiñe-Ofqui Fault System and the Andean Transverse Faults: Geophysical imaging of fluid pathways and practical implications for geothermal exploration

•We combined ERT, nakamura's method, and geological mapping to localize thermal water.•Hotspring's thermal water is fed by vertical conduits aligned with local faults.•Significant amount of hot water is dispersed in horizontal bodies within sediments.•The hydrothermal systems are twice longer within sediments than the hotspring area.•We present a model of the shallow anatomy of fault-controlled hydrothermal systems. We combined geoelectric and seismic ambient noise methods to image the shallow depth (
