“…The peculiarity of this method, proposed by [31], is the possibility of investigating the seismic vulnerability of buildings grouped in compounds through the vulnerability form depicted in Table 2. This form, based on the method proposed by Benedetti and Petrini many decades ago [32,33], is appropriate for masonry building aggregates, and uses five new parameters, additional with respect to the original form ten parameters proposed by the above-mentioned researchers, which take into account the effects of mutual interaction under earthquakes among aggregated Structural Units (S.Us). With regard to the five new added parameters, in order to obtain a form totally homogeneous with the previous one, the scores and weights assigned were calibrated numerically on the basis of the results of specific numerical parametric non-linear analyses.…”

The present research aims to estimate the influence of site amplification on the seismic vulnerability of the historical centre of the municipality of Baranello in the Molise Region of Italy. Firstly, a structural and typological characterization of the investigated area has been done according to the EMS-98 scale. Subsequently, the vulnerability assessment of the historical buildings located there has been carried out through an appropriate survey form in order to identify the buildings which are most susceptible to seismic damage. To this purpose, the seismic event occurring in October of 2002 has been selected as a reference earthquake. Moreover, according to the AeDES form implemented by the Italian Civil Protection Department to evaluate the usability of constructions after seismic events, the calibration of the typological vulnerability curves of the built-up area has been done, and a quantitative assessment of the local seismic response has been achieved, based on the seismic motions recorded after the 2002 Molise earthquake. Finally, the local amplification factor, which negatively influences the severity of the seismic damage on the structures, has been taken into account in order to more correctly foresee the expected damage of the inspected urban sector, so as to use more appropriately the achieved results for reliable seismic risk mitigation plans.

“…Its natural exposure to increased environmental pressures and historical protection requirements often limit the enhancement of its material performance [28]. Thus, many scholars have begun fragility research of the historic environment, investigating various disasters including climate disasters [29], geological disasters [30], fires [31], earthquakes [32,33], floods [34] as well as marine and aeolian processes [35].…”

The historic environmental vulnerability of traditional villages (HEVTVs) is distinctly differentiated; however, the priority of relevant emergency management practices still lacks appropriate evaluation. This study proposes a new assessment system to quantify HEVTVs at the district level and an extended analysis of the influencing factors of adaptive capacity. This provides a basis to classify the emergency management of villages under geological hazard risks. Based on the coupled human–environment system, this research designed the assessment with three criteria, six factors, and 13 indexes from the perspective of HEVTVs. Furthermore, a demonstration test was conducted of 148 traditional villages in Lishui, China. The results showed that 64.19% of HEVTVs in Lishui were moderate or above, and that villages with very high vulnerability were mainly distributed at mid-elevation of mountains with strongly sloping terrain. In contrast, low-vulnerability villages were generally on plains at low altitudes. Furthermore, three high-vulnerability clustering groups were identified as critical improvement targets for which special zoning strategies should be proposed. Five influencing factors were found to be strongly related to the adaptive capacity, indicating a spatial variation of the impact intensity. This could be applied to streamline vulnerability optimization strategies according to local conditions.

“…The inadequate architectural design of the buildings facing the earthquake had a strong relationship with the unexpected level of damage in the opinion of several authors [19]. The seismic vulnerability of the set of buildings in a city can be analyzed in different ways [23][24][25][26]. Its added value is usually the sum of various subparameters related to the architectural configuration of the building.…”

Featured Application: Implementation of an innovative approach in the field of seismic damage analysis in cities to hierarchize the importance of the different phenomena detected. Possible applications to develop improved mitigation strategies in urban areas.Abstract: The analysis of damage in cities after an earthquake to implement mitigation strategies of seismic risk is a complex job that is usually full of uncertainties. Numerous variables affect the final result of the observable damage in a set of buildings in an urban area. The use of methodologies capable of providing global explanations beyond the traditional unidisciplinary approach of disciplines, such as structural analysis, earthquake engineering, geotechnics, or seismology, can be very useful for improving the behavior of our cities against earthquakes. This article presents geostatistical post-earthquake analysis, an innovative approach in this field of research based on GIS spatial statistical tools to evaluate the importance of the different variables after an earthquake that may have caused damage in a city. This new framework will be applied to analyze, from a geostatistical perspective, the damage levels observed in the city of Lorca (Spain) after the earthquake of 2011; a case study where various studies have proposed different measures to mitigate the impact of future earthquakes as a consequence of focusing on different phenomena as the main variable for the damage produced. A bivariate GIS assessment will allow spatial correlation of the problems detected from a statistical point of view (inadequate design of buildings, age of the real estate stock, inefficient urban planning configurations, geological risk, etc.) and the different levels of damage that the technicians who participated in the post-earthquake phase evaluated in the city. The results obtained will allow one to hierarchize the importance of the different detected phenomena to prepare the city better against future earthquakes and to elaborate an improved seismic mitigation strategy.
