Abstract


In this paper we present a review of the seismotectonic features (an analysis of earthquake focal mechanisms and
the distribution of seismicity) of the Northern Apennines, Umbria Region (Italy) in the area between Sansepolcro
and Norcia. For this analysis, we used Centroid Moment Tensor (CMT) data for earthquakes with magnitude
M>5.0 and data computed by implementing the standard CMT algorithm to compute Regional Centroid Moment
Tensor (RCMT) estimates for moderate-magnitude earthquakes (4.5
