On 16 November 2006 a flank collapse affected the unstable eastern slope of South‐East Crater (SEC) Mount Etna. The occurred during one paroxysmal events with sustained strombolian activity that characterized August–December eruption and was triggered by erosion loose, hydrothermally altered material steep south‐east sector SEC from outpour lava. produced debris avalanche involved both lithic juvenile resulted in deposit emplaced on volcano up to 1.2 km away source. total volume estimated be order 330,000–413,000 m 3 . reconstruction event simulated using TITAN2D software designed model granular avalanches landslides. This approach can used estimate areas may similar future. area lateral small portion Etna summit area, but fact no killed or injured should considered fortuitous. adjacent volcano, fact, are usually visited many tourists who not prepared face this type danger. points need for through scientific investigation (analysis instability, numerical simulation flows) development specific civil protection plans.
