What to know about Deep beneath Swiss Alps, researchers trigger 8,000 tiny quakes in controlled test

Researchers from ETH Zurich conducted an experiment called FEAR-2 in the BedrettoLab beneath the Swiss Alps, triggering approximately 8,000 small seismic events by injecting water into a fault. The project aims to understand the mechanics of induced seismicity to improve safety for underground activities like excavation and geothermal energy production.

Why it matters

"It was a success!" said Domenico Giardini, one of the lead researchers on the project, as he inspected a crack in the rock wall lining a narrow tunnel far below the Swiss Alps.

Common ground

Wearing a fluorescent orange jumpsuit and helmet, the geology professor at the Federal Institute of Technology in Zurich (ETH Zurich) switched on his headlight to get a better look.
