Empirical rainfall thresholds for the triggering of landslides in the NW of the...

In this study, we provide a comprehensive review focused on the NW of the Iberian Peninsula identifying a great amount of research works, including 85 empirical rainfall thresholds for the triggering of landslides, some unpublished to date. While the compiled works provide valuable descriptive insights, the thresholds currently have limited predictive capability. The variety of data and approaches used by diffe...

People & Fire webGIS tool for wildfire risk assessment

People&Fire webGIS tool is an application for wildfire risk assessment, focused on obtaining simulating hazard and risk scenarios centred on land use transformation. This tool is a decisionsupport platform created in the context of a research project, which was dedicated to testing a new analytical framework for supporting the development and evaluation of new, integrated, and people-centred policy approaches t...

Physical vulnerability of buildings to rainfall and earthquake induced landslid...

This study assesses the physical vulnerability of buildings in the Lisbon Metropolitan Area (LMA) to landslides triggered by rainfall and earthquakes. The susceptibility to rainfall-induced landslides was evaluated using the Information Value statistical model and validated through ROC curve analysis. Additionally, the susceptibility to earthquake-induced landslides was assessed using the Analytic Hierarchy Pro...

Understanding flood risk in urban environments: spatial analysis of building vu...

Climate change has brought about new risks while exacerbating existing ones, with floods now accounting for about 45% of global disasters. This trend indicates that the exposure to floods and resulting damages will continue to rise. This paper aims to contribute to the global efforts to enhance flood resilience in urban areas by introducing a physical vulnerability index for buildings in flood-prone urban areas...

Landslide risk analysis in Portugal: an insight into the municipal level

Landslide susceptibility assessment using different rainfall event based landsl...

The present work aims to evaluate potential sources of uncertainty associated with rainfalltriggered event-based landslide inventories within the framework of landslide susceptibility assessment. Therefore, this study addresses the following questions: (i) How representative is an event-based landslide inventory map of the total landslide activity and distribution in a study area?; (ii) How reliable is an event...

Seasonal rockfall risk analysis in a touristic island: Application to the Tramu...

Rockfalls are an ever-present possibility in the mountainous context of the Tramuntana Region (Mallorca, Spain). Recent events have shown the high potential for direct and indirect impact on the safety of people and economic activities, lasting for weeks or even months. In the present study, we start from a probabilistic assessment of the rockfall hazard (spatial propensity and temporal recurrence), based on a ...
