Catalog of seismicity induced at Rittershoffen-ECOGI geothermal site during its development phase, according to Gaucher et al. (2025).

The authors analyzed the three successive stimulations of GRT-1 well (thermal, chemical and hydraulic ) carried out in 2013.

The catalog results from improved template matching and relative relocation, and contains over 3,000 seismic events.
