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a great amount of research works, including 85 empirical rainfall thresholds for the triggering of landslides, some unpublished to date.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...

Um Desfecho Infeliz de um Diagnóstico Evitável: Caso Clínico

O vírus da imunodeficiência humana (VIH) constitui uma das infeções sexualmente transmissíveis com maior impacto na vida do doente, sendo fundamental o diagnóstico precoce de forma a iniciar terapêutica antirretroviral atempadamente e evitar a evolução da doença.Apresentamos o caso de uma mulher de 60 anos com quadro de epigastralgia, ageusia e perda ponderal de 9% com 3 meses de evolução. Foi solicitado estudo...

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...

Umbrales de lluvia para el desencadenamiento de inestabilidades de ladera en el...

A great number of works focused on the calculation of empirical rainfall thresholds for the triggering of landslides have been develo-ped in the northern areas of Portugal and Spain. Because of a review, 103 thresholds have been compiled. More than 30% of them have not yet been published. The comparison of four regional thresholds highlights relevant differences linked to the use of multiple methodo-logies to d...

On the Physical Vulnerability of Buildings Exposed to Landslide Hazards in the ...

This study assesses the physical vulnerability of buildings (PVB) in the Lisbon Metropolitan Area (LMA) exposed to landslides triggered by both rainfall and earthquakes. Firstly, a statistical model (Information Value), validated with a ROC curve, was adopted to assess susceptibility to landslides caused by rainfall. Secondly, an Analytic Hierarchy Process was adopted to assess the susceptibility to landslides ...
