In this study, we compute some ground motion scenarios for the area surrounding the town of Vittorio Veneto (NE Italy). We use two different numerical approaches. In the first approach, called EXWIM, the earthquake source is represented by a rupture which propagates along an extended fault with a prescribed kinematics. With this method, we build ground motion scenarios at a regional scale for the Vittorio Veneto area. We consider two reference earthquakes, i.e. the historical M=5.8, Cansiglio event of October 18, 1936 and a hypothetical M=6.7 earthquake occurring in the Montello area, directly SW of Vittorio Veneto. With the second approach, called SPEM 2D, we take into account the effects of a complex crustal structure and local soil conditions on the propagating seismic waves. This method is used for the construction of a detailed ground shaking scenario for the Vittorio Veneto area and to estimate the effect of the wave-field propagation on the ground motion through the complex Alpago-Cansiglio geological structure.

Abstract

In this study, we compute some ground motion scenarios for the area surrounding the town of Vittorio Veneto (NE Italy). We use two different numerical approaches. In the first approach, called EXWIM, the earthquake source is represented by a rupture which propagates along an extended fault with a prescribed kinematics. With this method, we build ground motion scenarios at a regional scale for the Vittorio Veneto area. We consider two reference earthquakes, i.e. the historical M=5.8, Cansiglio event of October 18, 1936 and a hypothetical M=6.7 earthquake occurring in the Montello area, directly SW of Vittorio Veneto. With the second approach, called SPEM 2D, we take into account the effects of a complex crustal structure and local soil conditions on the propagating seismic waves. This method is used for the construction of a detailed ground shaking scenario for the Vittorio Veneto area and to estimate the effect of the wave-field propagation on the ground motion through the complex Alpago-Cansiglio geological structure.
