From Seismic Input to Damage Scenario: An Example for the Pilot Area of Mt. Etna Volcano (Italy) in the KnowRISK-Project

In this paper we present a multidisciplinary approach aimed at assessing
seismic risk regarding non-structural damage. The study has been carried out in the
framework of the European KnowRISK Project and focuses on the pilot area of
Mt. Etna volcano (Italy). Both instrumental data and as well as macroseismic
observations provide unique opportunities for testing innovative and classical
approaches for assessing seismic risk. Starting from the seismic hazard analysis,
we first identify a test site (Zafferana) affected by non-structural damage. We
produce seismic scenarios based on macroseismic and ground-motion data and
finally obtain the relevant risk map using the Italian census data to classify buildings
into vulnerability classes and a model to predict damage distribution.
