Scientists Trigger 8,000 Micro-Earthquakes in Swiss Alps for Seismic Research
Scientists at the BedrettoLab, an underground research facility located deep beneath the Swiss Alps, deliberately triggered approximately 8,000 small earthquakes to study seismic pressure buildup and the mechanics of deep earthquake initiation. Led by Professor Domenico Giardini of ETH Zurich, the four-day experiment, part of the FEAR-2 (Fault Activation and Earthquake Rupture) project, involved hundreds of sensors monitoring fault movements under 1.5 kilometers of rock. Although the team did not reach the targeted magnitude, the induced seismic events were successfully recorded by underground instruments while remaining imperceptible to people on the surface. The primary objective was to enhance understanding of how shifting rocks and accumulating pressure trigger earthquakes, aiming to mitigate future seismic risks. This collaborative effort included participation from several European countries and utilized specialized electric vehicles for access through narrow tunnels. The successful execution of this controlled experiment provides valuable data on fault behavior, offering insights that could improve earthquake prediction and safety measures. The findings highlight the capability to closely observe and induce fault movements in a safe, monitored environment, marking a significant step forward in seismological research.
