Mudflow and landslide hazard in changing climate – lesson from the 2023 Emilia Romagna catastrophe (Italy)

1) Detailed maps of mass-movement activity, hazard and risk on slopes under study and their surroundings (Emilia-Romagna, Italy) 2) Maps of land use compared to the extent and type of mass movements (Emilia-Romagna, Italy) 3) Geomorphological maps of sites under study (Emilia-Romagna, Italy) 4) Sets of processed and recalculated precipitation data (Emilia-Romagna, Italy) 5) Chronology of the activity of study mudflows and landslides based on all sampled trees (Emilia-Romagna, Italy) 6) Chronology of the activity of study mudflows and landslides based on all sampled trees (index of tree-ring eccentricity and reaction wood) (Emilia-Romagna, Italy) 7) Report on the hazard of a landslide and mudflow catastrophe (Emilia-Romagna, Italy) Data were used in: a) Malik I., Maerker M., Wistuba M., Gorczyca E., Torrese P., La Licata M., Yu Y., Woskowicz-Ślęzak B., Bieniasz A., 2025.
