Stressed faults continue to rupture, and they in turn change the stress

At this point it is unclear if only the Campi and Preci Faults ruptured, or if the Norcia Fault did as well. At M=6.6, surface rupture is likely, with 50-100 cm of slip expected, and so soon the answer will reveal itself by geological mapping, as well as by GPS, satellite radar, and seismic observations. What we can say at this point is that the M=6.6 shock is probably a compact, high-stress drop event, and that if it indeed ruptured the Campi and Preci Faults, stress has been transferred south onto the Norcia Fault, which is now in play.


In our judgment, the Norcia, Gorzano, Capitignano Faults could now be the next domino pieces to fall.
