چکیده
Abstract This paper investigates the spatial correlation of response spectral accelerations from a set broadband physics-based ground motion simulations generated for Norcia (Central Italy) area by means SPEED software. We produce several ground-motion scenarios varying either slip distribution or hypocentral location as well magnitude to systematically explore impact such physical parameters on correlations. extend our analysis other components (vertical, fault-parallel, fault-normal) in addition more classic geometric mean highlight possible directionality and therefore identify specific features. Our analyses provide useful insights role heterogeneities relative position between hypocentre asperities correlation. Indeed, we found significant variability terms both range sill among considered case studies, suggesting that is not only period-dependent, but also scenario-dependent. Finally, results reveal isotropy assumption may represent an oversimplification especially near-field thus it be unsuitable assessing seismic risk spatially-distributed infrastructures portfolios buildings.

A database of the coseismic effects following the 30 October 2016 Norcia earthquake in Central Italy
We provide a database of the coseismic geological surface effects following the Mw 6.5 Norcia earthquake that hit central Italy on 30 October 2016. This was one of the strongest seismic events to occur in Europe in the past thirty years, causing complex surface ruptures over an area of >400 km2. The database originated from the collaboration of several European teams (Open EMERGEO Working Group...

Variability of Near-Field Ground Motion from Dynamic Earthquake Rupture Simulations
This study investigates near-field ground motion variability due to dynamic rupture models with heterogeneity in the initial shear stress. Ground velocity seismograms are synthesized by convolving the time histories of slip velocity obtained from spontaneous dynamic rupture models with Green’s functions of the medium calculated with a discrete wavenumber / finite element method. Peak ground vel...
