In Brief

The BedrettoLab (Bedretto Underground Laboratory for Geosciences and Geoenergies) is a unique research infrastructure run by ETH Zurich making it possible to take a close look at the Earth’s interior. It is located in the Swiss Alps 1.5 kilometres below the surface and in the middle of a 5.2 kilometres long tunnel connecting the Ticino with the Furka railway tunnel.

Equipped with the latest technology, the BedrettoLab offers ideal conditions to conduct experimental research focusing on the behaviour of the deep underground when accessing and stimulating it. Such an access is required to advance scientific knowledge in various domains including geothermal energy and earthquake physics. It is also of relevance to develop novel techniques and sensors for these purposes.

Mangia e Cammina at the BedrettoLab

After a two year break, the local event Mangia e Cammina finally took place yesterday. For the first time, the BedrettoLab had the honor to be part of it and opened its doors once again for the public.

Mangia e Cammina attracted 1’300 visitors who hiked along a route through the Bedretto Valley, where several alps offered specialties from the region. The BedrettoLab was one destination on the Mangia e Cammina parkour and opened its doors for guided tours. Around 50 people walked additional 5 km trough the tunnel to visit  the BedrettoLab. In front of the tunnel, the BedrettoLab team and several helpers from ETH Zurich and SUPSI set up several booths where visitors could play a rock game, admire a small rock and mineral exhibition, see how a seismic station works or play an entertaining “snakes & ladders” game.

The event was an excellent occasion after a longer Covid related break to show our laboratory to the public. 8 August 2022

Summer break for VALTER Phase 2

With a rich data set gathered during the two stimulation cycles of the reservoir engineering phase (Phase 2), the VALTER project team now leaves for the summer break. Further stimulations of Phase 2 are scheduled for autumn.

After having conducted experimental stimulations in June and July, the VALTER team is pausing Phase 2 until the end of the summer. This time will be used to continue analysing the wealth of data that has been gathered and also allow team members to get a rest. The VALTER team is particularly interested in gaining a better understanding of the tiny, induced earthquakes that occurred within the reservoir and further away. Such events were expected to happen, however, exploring their occurrence in more detail is exactly what is needed to advance our understanding of the behaviour of the deep underground when stimulated in the context of a geothermal reservoir.
