Abstract

We present a 1:25,000 scale map of the coseismic surface ruptures following the 30 October 2016 Mw 6.5 Norcia normal faulting earthquake, central Italy. Detailed rupture mapping is based on almost 11,000 oblique photographs from helicopter and derived Structure-from-Motion photogrammetry, verified and integrated with field data (7000 measurements). Thanks to the common efforts of the Open EMERGEO Working Group (130 people, 25 research institutions and universities from Europe) we were able to detail a complex and impressive surface faulting pattern with an average strike of N155° and mainly the SW-side down along 20-25 km of the active Mt. Vettore - Mt. Bove fault system. A total cumulative surface rupture length of about 43 km, together with geometric and kinematic characteristics, were observed and recorded along closely-spaced, parallel or subparallel, overlapping or step-like synthetic and antithetic fault splays of the activated fault system.
