Empirical rainfall thresholds for the triggering of landslides in the NW of the...
Valenzuela, Pablo; Domínguez-Cuesta, María José; Pereira, Susana; Remondo, Juan; Bornaetxea, Txomin; Vaz, Teresa; Rivas, Victoria; Bonachea, JaimeIn 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a great amount of research works, including 85 empirical rainfall thresholds for the triggering of landslides, some unpublished to date.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...

Detección y análisis de subsidencia urbana en el Área Metropolitana de Lisboa (...
Cuervas-Mons, José; Domínguez-Cuesta, María José; Zêzere, José; Barra, Anna; Reyes-Carmona, Cristina; Monserrat, Oriol; Oliveira, Sérgio; Melo, RaquelEl Área Metropolitana de Lisboa, con una extensión de 4.390 km2 , está localizada en el centro de Portugal. El objetivo principal de este estudio ha sido detectar y analizar deformaciones del terreno asociadas a subsidencia urbana mediante técnicas de Interferometría SAR Diferencial Avanzadas (A-DInSAR). Para ello, se siguió el siguiente procedimiento metodológico: 1) selección y procesamiento de 48 imágenes SA...
Umbrales de lluvia para el desencadenamiento de inestabilidades de ladera en el...
Valenzuela, Pablo; Vaz, Teresa; Pereira, Susana; Domínguez-Cuesta, María José; Bornaetxea, Txomin; Rivas, Victoria; Remondo, JuanA 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...

Assessment of Urban Subsidence in the Lisbon Metropolitan Area (Central-West of...
Cuervas-Mons, José; Zêzere, José; Domínguez-Cuesta, María José; Barra, Anna; Reyes-Carmona, Cristina; Monserrat, Oriol; Oliveira, Sérgio; Melo, RaquelThe Lisbon metropolitan area (LMA, central-west of Portugal) has been severely affected by different geohazards (flooding episodes, landslides, subsidence, and earthquakes) that have generated considerable damage to properties and infrastructures, in the order of millions of euros per year. This study is focused on the analysis of subsidence, as related to urban and industrial activity. Utilizing the A-DInSAR d...
Empirical rainfall thresholds for the triggering of landslides in Asturias (NW ...
Valenzuela, Pablo; Zêzere, José; Domínguez-Cuesta, María José; Mora García, Manuel AntonioLandslides are one of the most serious geomorphological hazards in Asturias (NW Spain), where their temporal forecasting constitutes a key issue. The present work uses 559 records from the Principality of Asturias Landslide Database (BAPA) and daily precipitation data series from six rain gauges, gathered during a period of 8 hydrological years (2008–2016), to calculate empirical antecedent rainfall thresholds ...
