3-D magnetotelluric inversion for geothermal exploration in Socompa volcanic zone, NW Argentina

The Socompa volcano lies in the arid core of the Puna region. It is a stratovolcano whose summit reaches 6,051 m high and it is located between the limit of the Antofagasta region, Chile and the Province of Salta, Argentina. The volcano is located in a sterile environment, and the diversity and abun...
