“…At an urban scale, the seismic risk of a structure can be defined as the potential expected damage that may happen to it in a specified time frame of exposure [4]. This property is related to the seismic hazard (the probability of occurrence of a seismic event of certain severity in a specific site and during a determined period of exposure) and to the intrinsic predisposition of the building to be affected upon receiving the impact from a quake of a certain severity, expressed as seismic vulnerability.…”

Featured Application: Geographic Information System (GIS) estimation of ante-earthquake scenarios through a more functional and standardized method of seismic vulnerability evaluation of reinforced concrete buildings in urban areas. Abstract:In spite of the enhancements related to building construction, many regions still present a major level of seismic risk as a consequence of the high vulnerability of the urban configuration of their cities. An improved method to assess the seismic vulnerability of buildings in urban areas is proposed in this contribution in order to advance the management of seismic emergency scenarios. The methodology, mainly based on the cadastral database, allows for a more standardized implementation as a function on the typological, structural, and urban parameters of the buildings, reducing the level of uncertainties linked to these methodologies and giving continuity to the different RISK-UE published works. The generalization of the method to any urban area has also been improved by means of removing the parameters whose calibration is associated with a specific area. The methodology has been put into practice in the urban area of the city of Lorca (SE Spain), in the aftermath of the earthquake of 11 May 2011, due to the availability of well-documented data reported from this seismic event. The proposal, when it is combined with Geographic Information System (GIS) techniques, provides valuable information for the planning and management of post-earthquake emergency situations.

“…Without doubt this situation raises the levels of seismic vulnerability in many urban areas and the expected losses in the event of an earthquake. In this sense, the seismic vulnerability evaluation of existing buildings can be carried out using Mechanical or Macroseismic methods [4].…”

“…Urban seismic risk is the convolution of hazard and vulnerability; it describes the potential expected loss which can be represented in maps showing the expected damage of the urban area due to a specified earthquake. Although these definitions make reference only to physical aspects, vulnerability can also include economic, social or political aspects (Carreño et al 2007a;Barbat et al 2009). In this case, risk expresses the probability of exceedance of a given level of economic, social or environmental consequences, at a certain site and during a certain period.…”

The Vulnerability Index Method, in its version developed in the framework of the European project Risk-UE, has been adapted and applied in this article, to evaluate the seismic risk for the city of Barcelona (Spain) through a GIS based tool. According to this method, which defines five damage states, the action is expressed in terms of the macroseismic intensity and the seismic quality of the buildings by means of a vulnerability index. The probabilities of damage states are obtained considering a binomial or betaequivalent probability distribution. The most relevant seismic risk evaluation results obtained, for current buildings and monuments of Barcelona, are given in the article as scenarios of expected losses.

“…It is worth noting that, for management purposes, risk requires a multidisciplinary evaluation that takes into account not only the expected physical damage, but also damage to population and economic losses (ATC-13 1985;Coburn and Spence 2002;Vacareanu et al 2004) as well as other societal and policy related aspects (Carreño et al 2007; Barbat et al 2010). First, the expected direct physical damage to dwellings is analyzed, and then casualties, economic losses and volume of debris produced by such seismic crises are estimated.…”

The Capacity Spectrum Based Method developed in the framework of the European project Risk-UE has been applied to evaluate the seismic risk for the city of Barcelona, Spain. Accordingly, four damage states are defined for the buildings, the action is expressed in terms of spectral values and the seismic quality of the buildings, that is, their vulnerability, is evaluated by means of capacity spectra. The probabilities of the damage states are obtained considering a lognormal probability distribution. The most relevant seismic risk evaluation results obtained for Barcelona, Spain, are given in the article as scenarios of expected losses.
