Description:
On December 30, 2002, following an intense
period of activity of Stromboli volcano (south Tyrrhenian
Sea, Italy), complex mass failures occurred on the northwest
slope of the mountain which also involved the underwater
portion of the volcanic edifice for a total volume of
about 2–3×107 m3. Two main landslides occurred within
a time separation of 7 min, and both set tsunami waves in
motion that hit the coasts of Stromboli causing injuries to
three people and severe damage to buildings and structures.
The tsunamis also caused damage on the island of Panarea,
some 20 km to the SSE from the source. They were observed
all over the Aeolian archipelago, at the island of
Ustica to the west, along the northern Sicily coasts to the
south as well as along the Tyrrhenian coasts of Calabria to
the east and in Campania to the north. This paper presents
field observations that were made in the days and weeks
immediately following the events. The results of the quantitative
investigations undertaken in the most affected places,
namely along the coasts of Stromboli and on the island of
Panarea, are reported in order to highlight the dynamics
of the attacking waves and their impact on the physical
environment, on the coastal structures and on the coastal
residential zone. In Stromboli, the tsunami waves were
most violent along the northern and northeastern coastal
belt between Punta Frontone and the village of Scari, with
maximum runup heights of about 11 m measured on the
beach of Spiaggia Longa. Measured runups were observed to decay rapidly with distance from the source, typical of
tsunami waves generated by limited-area sources such as
landslides.
