**About the Editors**

**Samuele Segoni** graduated in Geological Sciences at the University of Firenze, Italy, and in 2008, he obtained a PhD in Earth Sciences, also at the University of Firenze. Since 2005, he has been carrying out research and teaching activities at the Department of Earth Sciences of the University of Firenze, where he is currently enrolled as Assistant Professor. Since 2019, he has been Chair Associate at the UNESCO Chair on the Prevention and Sustainable Management of Geo-hydrological Hazards. His main research topics are: the prediction and mapping of landslide hazards; application of physically based models for the triggering of shallow landslides at regional scale; landslide susceptibility assessment, statistical rainfall thresholds for landslide triggering, regional scale landslide early warning systems; civil protection, land planning, landslide risk assessment. Within these topics, he authored more than 50 peer-reviewed articles in international journals, and he is the member of Editorial Boards of various international journals.

**Stefano Luigi Gariano**, Ph.D., is a research scientist at the Research Institute for Geo-Hydrological Protection of the Italian National Research Council (CNR IRPI) in Perugia, Italy. He graduated in Environmental Engineering from the University of Calabria, Italy, and achieved a Ph.D. in Geology with a thesis on the impact of climate change on landslides from the University of Perugia, Italy. His main research topics include: (i) analysis of rainfall time series and of series of landslide occurrences; (ii) objective and reproducible reconstruction of rainfall conditions responsible for landslide occurrence; (iii) definition and validation of empirical rainfall thresholds for the possible initiation of landslides; (iv) evaluation of the impact of climate and environmental changes on landslides; (v) national and regional early warning systems for rainfall-induced landslides, in different climatic and physiographic environments. He is involved in several projects, mostly focused on the operational prediction of rainfall-induced landslides. He has authored more than 100 publications, including more than 40 peer-reviewed articles in international journals. He is organizing and convening scientific sessions on landslide early warning systems and on climate change effects on landslides at various international conferences. He is a founding member of "LandAware", the international network on Landslide Early Warning Systems and he is an Alternative Board Member for CNR IRPI at the International Consortium on Landslides.

**Ascanio Rosi** is currently working as a fixed-term research scientist at the Department of Earth Sciences of the University of Florence, where he obtained his PhD in Earth Sciences in 2013, with a thesis on the use of satellite radar data for subsidence and landslide mapping. From 2019, he has been a Chair Associate at the UNESCO Chair on Prevention and Sustainable Management of Geo-hydrological Hazards. His main research topics are the use of new technologies to create landslide databases; the identification of rainfall condition associated with the triggering of landslides; the use of artificial intelligence techniques to identify the geological and meteorological condition associated with the initiation of landslides; the development of landslide early warning system based on empirical and statistical analyses and landslide risk assessment. From 2012, he authored and co-authored over 20 articles in international journals; he also served as a reviewer and an editor for several international journals.
