Abstract:
In the framework of the GEMEX project (cooperation between Europe and Mexico for geothermal development), a dense network of 45 seismic stations was deployed in 2017-2018 at Los Humeros geothermal reservoir (Mexico).

In this work, we show updated Enhanced Seismic Tomography of the P and S waves that probed the geothermal reservoir down to 4-5 km of depth.

Th resolution achieved allows to describe with unprecedented detail several known features of the reservoir and to observe new structures that may explain the seismic response of the reservoir and the heterogeneous distribution of the heat sources.

This work is performed in the framework of the Mexican European consortium GeMex (Cooperation in Geothermal energy research Europe-Mexico, PT5.2 N: 267084 funded by CONACyT- SENER: S0019, 2015-04, and Horizon 2020, grant agreement No. 727550). We thank CFE for the access to the power plant.
