Earthquakes risk

This paper conducts quantitative and qualitative research to analyze how traditional dwellings were transformed during the reconstruction of four historic neighborhoods in the Kathmandu Valley following the Nepal earthquake. The transformation and modification of a traditional housing stock is evaluated through a combination of the direct impact of the earthquake, the application of modern earthquake-resistant building technology, the costs and logistics of reconstruction, and the priorities of local residents.

The Disaster Risk Management Knowledge Centre has produced the second scientific report. The report represents a collaborative effort of more than 300 disaster risk experts from different sectors and disciplines who have worked together for more than 2 years to present the consequences of disasters on various assets at risk (population, economic sectors, critical infrastructure, ecosystem services and cultural heritage).

Este estudio presenta una evaluación simplificada para valorar la probabilidad de daños debidos a los movimientos sísmicos en los Sitios del Patrimonio Mundial de la UNESCO en toda Europa.

The Disaster Risk Management Knowledge Centre has produced the first scientific flagship report "Science for Disaster Risk Management 2017: knowing better and losing less". The Disaster Risk Management Knowledge Centre has produced this report, the result of a multi-sectoral and multidisciplinary networking process representing the combined efforts of more than two hundred experts, mostly European. It aims to support the integration of science into informed decision-making by synthesizing and translating the evidence for disaster risk management and strengthening the science-policy and science-operation interface.

The document introduces a simplified methodology for risk assessment specifically developed for immovable cultural heritage. It encompasses the different components necessary for risk evaluation and can serve as a screening tool for the preliminary analysis of a large number of cultural properties, especially those with limited resources. It's also adaptable for cultural assets requiring a more detailed risk assessment.The proposed methodology is qualitative, relying on a set of structured questionnaires that integrate the key components of risk assessment: probability, consequences of the hazard, vulnerability of the property to the hazard's effects, loss of property value, and recovery capability post-incident. To illustrate its application, a case study is presented examining the seismic risk of a church in Italy damaged by the L'Aquila earthquake in 2009.
La metodología propuesta es un método cualitativo basado en un conjunto de cuestionarios estructurados que integran los principales componentes de una evaluación de riesgos: la probabilidad, consecuencias del peligro, la vulnerabilidad del bien a los efectos del peligro, la pérdida de valor de la propiedad y la capacidad de recuperación tras el suceso. Para ilustrar su aplicación se presenta un estudio de caso que analiza el riesgo sísmico de una iglesia en Italia que fue dañado por el terremoto de L'Aquila en 2009

The seismic evaluation of art objects requires a multidisciplinary approach and the definition of a methodology to assess the level of safety and the possible interventions necessary for the prevention of seismic risk, seeking a compromise between safety and conservation. This article describes a first step in this direction, in which the different aspects of the procedure, from the path of knowledge of the art object to the structural analysis, were studied on the six statues of Michelangelo located in the "Galleria dei Prigioni" (Slaves Gallery) of the Galleria dell'Accademia in Florence. We have shown that the general principles and criteria expressed in the "Italian Guidelines for the evaluation and mitigation of seismic risk of cultural heritage", which are specifically dedicated to masonry constructions, could be usefully extended to other works of art such as statues, starting from historical research, geometrical study and characterization of materials, to the development of specific methods of analysis. This research could be the basis for future studies on the prevention of seismic damage to art objects, including minimal interventions and specific devices, such as isolation systems.
