Quantitative seismic risk evaluation and mapping : cases of schools and residential facilities in Lisbon and Algarve

Abstract

This contribution deals with activities within the framework of an EC-project, entitled "UPStrat-MAFA (Urban prevention strategies using macroseismic and fault sources)", emphasising the inventory, vulnerability and seismic risk of buildings. The cases considered deal with elementary and non-elementary public schools as well as the residential building stock in Lisbon and Algarve in mainland Portugal. A new concept of global disruption measures is introduced and discussed, with the objective of providing a systematic way to quantify earthquake impact in urban areas. This approach provides civil protection, the authorities and local decision makers with a new tool judged to be valuable in prioritizing mitigation measures and responses.
