Description:
Bearing in mind the destructive potential of tsunamis
induced by volcanic landslides, the tsunamigenic event occurring
at Stromboli volcano in Italy on 30 December 2002 has been reexamined
here, by means of visible images and slope stability analysis.
This was one of the few examples in the world of a flank collapse
occurring at a volcano that was directly observed. We present
the results of stability analyses, together with a sequence of photos
collected from a helicopter a few minutes before the collapse. The
result of this study is that the sequence of landslides triggering the
2002 Stromboli tsunami can be defined as the final stage of a lateral
magma intrusion that exerted a high thrust at high altitude, destabilizing
the entire slope. This study allows a more complete understanding
of the event that took place on Stromboli on 30 December
2002. Furthermore, the approach used here, if appropriately modified,
can be used in other contexts, contributing to the understanding
of the condition that leads to tsunamigenic landslides
