On the multi-hazard risk assessment of urban areas: identification and analysis...

The development of integrated decision-support tools, able to assess multiple hazards at the regional and local scales, is a fundamental step to enhance the preparedness of urban areas to mitigate present and future risks arising from climate change. Understanding multi-hazard risk can help prioritize resilience-increasing actions and disaster prevention measures and form the basis for exploring institutional a...

Exposure and physical vulnerability indicators to assess seismic risk in urban ...

Understanding the impacts of multi-hazard risk in urban areas is a fundamental step towards the adoption of resilience-enhancement and disaster prevention strategies, underpinning institutional adjustments aimed at improving the capacity of the authorities and stakeholders to manage risk. Within this framework, the work presented in this paper seeks to identify and analyze a set of exposure and buildings' physi...

Determinação dos tempos de evacuação pedestre da população exposta a movimentos...

As regiões de montanha são áreas suscetíveis à ocorrência de movimentos de vertente com velocidades consideráveis. Neste contexto, o desenvolvimento urbano nestas áreas provoca um aumento da exposição da população, estruturas e infraestruturas a este tipo de perigo, o que frequentemente conduz a perdas de vidas e a graves impactos socioeconómicos. No presente trabalho, pretende-se identificar os edifícios em ri...

Application of dynamic modelling to identify buildings at risk and pedestrian t...

Debris flows are one of the most hazardous types of landslides in mountain regions. In the upper part of the Zêzere valley (Serra da Estrela, Portugal) several debris flows events occurred in the last 200 years, some of them causing loss of lives and material damages. In this work, a methodology for pedestrian evacuation modelling, in a debris flow hazard scenario, was implemented. A dynamic run-out model was u...

Landslides in a changing climate: assessment of hazard and exposure in the Arrá...

This work aims to assess the landslide hazard, nowadays and at the end of the 21st century, considering the SSP2-4.5 and SSP5-8.5climate change scenarios. The exposure of residential buildings, roads and strategic equipment to landslide hazard is also assessed. The study area is a small alpine orogenic chain – the Arrábida - characterised by a complex geomorphology, developing along 35 km in the southern part o...

On the physical vulnerability of buildings exposed to landslide hazard: applica...

This work aims to assess the physical vulnerability of buildings (PVB) exposed to landslides that can be triggered by rainfall and earthquake in the Lisbon metropolitan area (LMA). Susceptibility to landslides triggered by rainfall was assessed with a statistical model (Information Value), using seven predisposing factors: slope, aspect, geology, curvature, land use, and topographic wetness and position (TPI) i...

The role of susceptibility, exposure and vulnerability as drivers of food disas...

Fluvial fooding continues to be a process that has a major impact on society, the environment and the economy. Although its natural triggering factors, the spatial confguration of exposure and vulnerability is expected to play a relevant role in explaining the damage records. The starting point of this research is the use of existing food susceptibility, exposure and social vulnerability mapping, produced at th...

Multi-Hazard WebGIS Platform for Coastal Regions

The combined action of waves, surges and tides can cause flooding, erosion and dune and structure overtopping in many coastal regions. Addressing emergency and risk management in these areas require a combination of targeted campaigns and real-time data that measure all phenomena at stake and can be used to develop comprehensive monitoring platforms. These monitoring platforms can support the development of pre...
