The first FEAR-2 experiment, involving approximately 50 hours of controlled injection and continuous 24/7 monitoring between 22 and 25 April, was concluded on Saturday, 25 April. For the research team, the experiment was successful and demonstrated that the experimental design works and that seismicity can be induced in a controlled manner. 

The BedrettoLab is preparing the next step in the Fault Activation and Earthquake Rupture (FEAR) project: the FEAR-2 experiment. In this experiment, scientists will inject water into a densely instrumented natural fault zone to trigger a small, controlled earthquake of about magnitude 1. An earthquake of this magnitude cannot be felt at the surface, but it is large enough to help researchers understand how earthquakes start and how faults behave.
