abstract

• The active volcanic caldera of Acoculco has been explored in the last few years to develop geothermal energy from non-conventional sources. This caldera located in eastern Mexico has been classified as a Hot Dry Rock geothermal system. Our results bring a new understanding to the interaction between two intra-caldera fault systems in terms of their permeability and degassing processes through self-potential, temperature, and CO2 flux surveys. We demonstrate the absence of hydrothermal fluid circulation with convective activity, and we provide new evidence for the origin of cold degassing. These outcomes may have important implications for future exploitation targets in the area. © 2022
