Abstract
A procedure for seismic risk assessment is applied to the Mt. Etna area (eastern
Sicily, Italy) through assessment of urban system dysfunction following the occurrence of an
earthquake.The tool used is based on the Disruption Index as a concept implemented in Simulator
QuakeIST, which defines urban disruption following a natural disaster. The first element of the
procedure is the definition of the seismic input, which is based on information about historical
seismicity and seismogenic faults. The second element is computation of seismic impact on the
building stock and infrastructure in the area considered. Information on urban-scale vulnerability
was collected and a geographic information system was used to organise the data relating to
buildings and network systems (e.g., building stock, schools, strategic structures, lifelines). The
central idea underlying the definition of the Disruption Index is identification and evaluation of the
impact on a target community through the physical elements that most contribute to severe
disruption. The procedure applied in this study (i.e., software and data) constitutes a very useful
operational tool to drive the development of strategies to minimise risks from earthquakes.
