Description:
[1] We constructed a three-dimensional conceptual model of a geothermal system on the Caribbean island of Montserrat. The model was generated using magnetotelluric resistivity data, earthquake hypocenter data and a three-dimensional P-wave velocity model all plotted using a shared geographical reference. The results of the study suggest a high-temperature fracture controlled geothermal system at the intersection of two faults in the SW of the island. We also present a ‘prospectivity index’ map that represents a proxy of the spatial variation in harvestable heat flux at 1500 m depth. The index is the product of relative permeability around modeled faults and a proxy for the subsurface temperature calculated using P-wave velocity anomalies.
