A probabilistic approach for the classification of earthquakes as ‘triggered’ or ‘not triggered’

We introduce a combined statistical and physical approach to quantify the probability that a given earthquake was triggered by a given stress-inducing phenomenon

Scholarcy highlights

  • The occurrence time of earthquakes can be anticipated or delayed by external phenomena that induce strain energy changes on the faults
  • For a constant shear stressing rate, γ is equal to \(\gamma_0 = 1/\dot\tau\), which yields R = r: The seismicity rate remains at its constant background value until an external stress perturbation intervenes
  • After a step-like stress change, the tectonic stressing rate dominates in controlling the seismicity rate, which experiences a transient until it reaches again steady state
  • Setting \({\rm d}S=\dot\tau\,{\rm d}t\) Eq 19 and integrating:
