Abstract
High resolution seismic data, we collected in the Ionian sea, reveal large submarine landslide deposits offshore from Mt.
Etna (Italy), spatially consistent with the eastern flank collapse of this volcano. A large debris-avalanche deposit, we relate
to the Valle del Bove scar, displays long offshore run-outs (till 20 km) and a volume of a few tens of cubic kilometres (16–21
km3). Other landslide deposits are also imaged, in particular a striking unique record of the relative timing of multiple submarine
large slump events.
