Landslides in the North of Lisbon Region (Portugal): conditioning and triggering factors
JL Zêzere, AB Ferreira, ML Rodrigues - Physics and Chemistry of the Earth …, 1999 - Elsevier
Detailed geomorphological mapping carried out in 5 sample areas in the North of Lisbon
Region allowed us to collect a set of geological and geomorphological data and to correlate
them with the spatial occurrence of landslide. A total of 597 slope movements were identified
in a total area of 61.7 km2, which represents about 10 landslides per km2. The main
landslide conditioning factors are: lithology and geological structure, slope angle and slope
morphology, land use, presence of old landslides, and human activity. The highest landslide …
