Short summary
Induced earthquakes present a major obstacle for developing geoenergy resources. These occur during hydraulic stimulations that enhance fluid pathways in the rock. In the Bedretto Underground Laboratory, hydraulic stimulations are investigated in a downscaled manner. A workflow to analyze the hazard posed by induced earthquakes is applied at different stages of the test program. The hazard estimates illustrate the difficulty in reducing the uncertainty due to the variable seismogenic responses.
