“…This proposal standardizes the RISK-UE curves by empirical damage models, consistent with the fuzzy set theory. Similar to the qualitative definitions interpreted through membership functions χ proposed by previous studies [23,25] for the vulnerability categories of the EMS-98 scale, RISK-UE considers a series of membership functions for each structural configuration. A function χ defines the belonging of single values of a certain parameter to a specific set: the value of χ is 1 when the degree of belonging is reasonable; between 0 and 1 shows that the value of the parameter is infrequent but possible; and χ…”

“…Since the previous described version [18] a series of reviews have been performed in the definition and numerical evaluation of these behavior modifiers [23,25,28,29], calibrating the influence of several dispositions (i.e., sloping ground difference of height between close buildings, irregularity in plant or elevation, etc. ), in the seismic analysis of buildings.…”

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.

“…Over the last few decades, seismic risk evaluation, as well as that for other natural hazards, is of increasing concern and considered to have an essential role in the urban planning and risk management of prone areas (Campos Costa et al 2009;Lantada et al 2010) such as the Azores archipelago. The development of vulnerability assessment studies, in urban centres or rural areas, fundamentally aim to mitigate seismic risk, as well as identify building fragilities.…”

The earthquake of the 9th of July 1998 that hit in the central group of the Azores archipelago greatly affected the islands of Faial, Pico and São Jorge, reaching a magnitude of Mw 6.2 with the epicentre located about 15 km northeast of the Faial Island. This earthquake allowed the collection of an unprecedented quantity of data concerning the characterisation of the building stock and the damage suffered by construction. This is the main purpose of this research, consisting essentially of three main aspects: (i) A detailed characterisation of the building stock, assigning a five category classification, from old traditional rubble stone masonry to reinforced concrete moment framed buildings; (ii) A detailed damage grade classification based on the different damage mechanisms observed; and, (iii) A seismic vulnerability assessment of the building stock. The results of the vulnerability assessment together with the building stock database and damage classification were integrated into a GIS tool, allowing the spatial visualation of damage scenarios, which is potentially useful for the planning of emergency response strategies and retrofitting priorities to mitigate and manage seismic risk.

“…Seismic risk in urban areas is defined as the convolution of 'seismic hazard' and 'seismic vulnerability' [1,2]. While studies on the seismic hazard analysis (SHA) provide a conceptual framework for evaluating the probability of the occurrence of the hazard, the 'vulnerability assessment' is used to determine the likely effects of hazards on human beings and property within a particular area [3].…”

Earthquakes are one of the natural disasters that threaten many lives every year. It is important to estimate seismic damages in advance to be able to reduce future losses. However, seismic vulnerability assessment is a complicated problem, especially in areas with incomplete data, due to incorporated uncertainties. Therefore, it is important to use adequate methods that take into account and handle the associated uncertainties. Although different seismic vulnerability assessment methods at the urban scale have been proposed, the purpose of this research is to introduce a new Geospatial Information System GIS-based model using a modified integration of Analytical Hierarchy Process (AHP), fuzzy sets theory, and Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) in a vector-based environment. The proposed method emphasizes handling one of the important uncertainties in areas with incomplete data, namely the 'vagueness' of the existing knowledge about influences of the criteria on seismic vulnerability, which is handled using fuzzy sets theory in this research. The applicability of the proposed method is tested in a municipality district of Tabriz, which is in a near vicinity to the fault system. It can be concluded that the proposed method contributes to a pragmatic and efficient assessment of physical seismic vulnerability under uncertainty, which provides useful information for assisting planners in mitigation and preparation stages in less-studied areas.
