This paper presents a preliminary susceptibility map of the flood hazard
for the Somma-Vesuvius volcanic district, worked out by means of multidisciplinary
historical, geological, geomorphological and rainfall data
processing. It is well known that the Somma-Vesuvius volcano, due to its
explosive volcanism and the dense urbanization of the surrounding area,
with a population exceeding 650,000 is one of the most dangerous active
volcanoes of the world. Although this area has been extensively studied
from the volcanological point of view with regards to its volcanic hazard,
there are currently not many detailed studies about its flood hazard factors,
despite the fact that, in the last century, many intense rainfall events
in this area have produced several floods that invaded the surrounding
plains affecting towns and roads, and causing much damages and loss of
lives. Accordingly, in this paper high-resolution DEM (5×5 m pixel) and
detailed geomorphological maps of the whole area have been analyzed
and processed in GIS environment, carrying out a comparative study of
the present-day morphology and the morphology of the 1900’s volcanic edifice,
including changes of infrastructures and buildings throughout the
last century. These results, together with historical chronicles data and
the rainfall accurate data for all flood events, have been processed in this
paper for highlighting the drainage basins areas of Somma-Vesuvius
where the flood phenomena could be more probable in the future, working
out a preliminary zoning map, also suggesting in which sectors interventions
useful for mitigation of flood risk should be implemented.
