An international team of researchers from Geoazur, École des Ponts ParisTech, and Dalhousie University has just taken a significant step forward in understanding how earthquakes are triggered. Their work, published in the journal *Nature* on May 6, 2026, offers new insights into the physical mechanisms behind earthquakes.
Before an earthquake occurs, a fault enters a phase known as “nucleation,” which is still poorly understood. By replicating fault behavior in the laboratory, researchers have demonstrated that small precursor tremors, known as foreshocks, directly influence the dynamics of this phase and can determine how quickly an earthquake is triggered.
These findings challenge conventional models and highlight the importance of initial conditions in the rupture process. They offer a new framework for interpreting the precursor signals observed before certain earthquakes, a major challenge for better understanding—and ultimately better anticipating—seismic risk.
