Swiss Contribution

The department of Earth Sciences at the University of Geneva is dedicated to the advancement of fundamental research as well as to its application to societal problems, such as the management of natural resources, the identification of risks posed by natural hazards, and the consequences of human activities on the environment. The group of Crustal Deformation and Fluid Flow investigates crustal processes combining geophysical and numerical methods with geological observations.


The Domo San Pedro Geothermal field, Mexico, is a high-enthalpy geothermal system with an installed capacity of 35 MW. Grupo Dragon, the operator exploiting the geothermal field drilled already nine wells ranging from about 1500m to 3000m depth. Grupo Dragon is planning to expand its production with the drilling of two additional wells, and to measure the linked seismic activity for a better risk assessment.

The University of Geneva aims to transfer to Grupo Dragon and to the Mexican geothermal community the know-how on how to effectively use affordable passive seismic methods in a geothermal context. DOS PEGAS will deploy 20 seismic stations (provided by UNIGE) to monitor seismic activity during stimulation and further acquisition of passive seismic data.
