Cálculo de Escenarios de Daños Sísmicos en la Comunidad Valenciana utilizando Model Builder (ArcGIS)s

Resum

In this paper we present a tool wich allows a quick simulation of Seismic Damage Scenarios (SDS) from any earthquake occurred within Valencian Community. For its design we have used ArcGIS Model Builder application. The input data required for the simulation are: the earthquake, the lithological cartography, municipalities with their building census, a damage probability matrices and the municipalities’ population census. Using seismic wave attenuation laws and considering the local effect, the tool calculates the seismic shaking expressed in seismic intensity (EMS-98). Then, with the Vulnerability Index Method (VIM) it obtains building damages (mild, moderated and serious) through the application of damage probability matrices. Finally, population damages (people with minor or serious injuries, deads and homeless) are calculated using the ATC-13 method proposed by the ATC (Applied Technology Council). Obtained results are represented in several maps. In this way we have implemented a useful tool in studies of municipal planning for facing seismic risk, like Protección Civil Actuation Plans.
