Slope failures at high elevation in the Italian Alps in the period 2000-2020

This dataset implements and updates with 106 new records the one published by Paranunzio et al. 2019 (doi:10.1594/PANGAEA.903761). The two datasets have the same survey methodology, making the new dataset homogeneous with the previous one. All together, we collected and validated a dataset of 392 slope instability events documented from 2000 to 2020, at high elevation (above 1500 m a.s.l.) in the Italian Alps. The dataset includes landslides, blockfalls, rockfalls, soil slips, rock avalanches and complex landslides. It was realized in the framework of a study aimed to assess the susceptibility to failure of slopes with specific geomorphological characteristics and the role of climatic elements in the preparation and/or triggering of slope instability. At present, this is the most comprehensive dataset on slope failures occurred at high elevation in the Italian Alps in the last two decades. This work is intended as a contribution to the creation of an alpine/global dataset of slope failures at high elevation, useful for studying the impacts of climate change on fragile mountain environments.
