ABSTRACT
In this study two coastal areas of Portugal were selected (Fig. 1): Figueira da Foz, located in the central region of Portugal and Setubal located nearby Lisbon. Therefore, the objective of this study is to propose a multidimensional vulnerability analysis for coastal areas with a potential
1 INTRODUCTION
The evaluation of the degree of exposure and vulnerability to natural disasters in the last decade has seen a notable increase (Wisner et al., 2004; Douglas, 2007). Even after the 2004 India Ocean Tsunami, and more recently the 2011 Japan Tsunami there has been a focus on the hazard process assessment and mapping through physical models (Liu et al., 2007; Santos et al., 2007; Santos, 2011; Satake et al., 2011; Singh et al., 2012). Other approaches have been focusing on the analysis of territorial vulnerability resulting from past impact in predicting future events (DomineyHowes and Papathoma, 2007; Dall’Osso et al., 2009; Dominey-Howes et al., 2009; Hart and Knight, 2009; Dominey-Howes et al., 2010). On the other hand, several studies have been pointing the importance of conceptual requirements and technical problems for territorial vulnerability assessment, like the scale analysis (Fekete et al., 2010; Kienberger et al., 2013), the perception of natural and technological risks (Tavares et al., 2011), the supporting data (Papathoma et al., 2003; Silva and Pereira, 2014) and the comparativeness
tsunami hazardous impact. First is calculated the morphological index of vulnerability (Mv) that combines the different physical and occupation characteristics of the analyzed area. Secondly, is calculated the structural vulnerability index (Bv) that estimates the vulnerability of the different potentially affected buildings. Thirdly, the social vulnerability (Sv) that analyzes the socioeconomic characteristic of the study area is calculated.
