Mapping the slip rate and geometry of the Aremogna Fault, central Apennines, Italy

Abstract

In order to understand the seismic hazard posed by an active faults it is necessary to know (i) the long-term rate of movement of the fault; (ii) the geometry of the fault; and (iii) the time that has elapsed since the last earthquake occurred on the fault. This study aimed to improve the information known about the Aremogna-Cinque Miglia Fault in the central Apennines, Italy. We collected a real-time kinematic GPS survey of the southeastern tip of the Aremogna segment of the Fault (Figure 1) to map the surface trace of the fault, and map the offset of the fault. This was combined with a ground penetrating radar (GPR) survey across the fault.
