This photograph taken on April 29, 2026 shows the tunnel to the BedrettoLab, a unique underground research facility operated by the Federal Institute of Technology Zurich (ETH Zurich) located 1500m beneath the Swiss Alps within a 5.2 km tunnel near Bedretto. Researchers have made the ground shake triggering thousands of tiny earthquakes in a monitored setting, as they seek to discover seismicity insights that can reduce risks.
