Seismicity in the BedrettoLab during hydraulic stimulations
A recently published study investigates induced seismicity during hydraulic stimulations at 1.1 km depth in the BedrettoLab, Switzerland, to better understand seismic behavior in enhanced geothermal systems.
Construction update: First section of new side tunnel finished
This week, the first section of the new side tunnel, the so-called FEAR tunnel, was completed, reaching a current length of approximately 20 meters. The complete FEAR tunnel will be 120 meters long. Parallel to the excavation work, 11 boreholes with a total length of around 190 metres were drilled.
The second multi-day hydraulic stimulation was finished successfully at the end of August. A team of about ten people monitored a stimulation lasting for about three days, injecting water with a pressure of 20 MPa.
Guided tours of the BedrettoLab available to the public from summer 2024
In partnership with the Sasso San Gottardo Museum, ETH Zurich will be offering guided tours of the BedrettoLab to the public from summer 2024. These tours, which will be available on three Saturdays, will be laid on in German and Italian.
First long-term injection experiment successfully finished
At the end of April, the BedrettoLab team successfully conducted their first long-term injection experiment. The experiment lasted several days aiming to generate an earthquake of about magnitude 0 and monitor it from close by.
Last Saturday 14 team members participated at the SOLA Staffette, a relay race covering a total of 113 km in and around the city of Zurich. The team finished in 545th place out of 997 teams and was the fastest among many teams from the Earth Science Department of ETH Zurich.
