Short summary
We demonstrate that coarse gravel deposition in the catchment basins of the major rivers of central Italy is a direct proxy of global deglaciation events associated with meltwater pulses. By precise 40Ar/39Ar dating of the sedimentary deposits we show that emplacement of these gravel beds is closely coincident with discrete events of sea-level rise, with peaks of the Ice-rafted debris (IRD) curve, and with particularly mild (warmer) minima of mean summer insolation at 65° N.

Short summary
Rock avalanches are extremely dangerous, causing much damage worldwide. The
Masiere di Vedanais a rock avalanche deposit (9 km2, 170 Mm3) in NE Italy. We dated it back to late Roman to early Middle Ages. Identified drivers are the overall structural setting, exceptional rainfall events and seismic shakings. No exceptional event is required as a trigger. When dealing with heavily deformed bedrocks, especially in inhabited areas, the occurrence of a huge event like this must be considered.

Short summary
For better knowledge of the climate perturbation that occurred in the lattermost part of the Triassic (Norian–Rhaetian), we investigated the geochemical and rock magnetic properties of the limestones of the Pignola–Abriola section (Lagonegro Basin, Italy). Our investigation revealed at least a major episode of enhanced weathering occurring in the late Norian (~217–211 Ma), possibly related to the Cimmerian orogen and/or the northward motion of Pangea across the equatorial humid belt.
