Abstract
Calabria (southern Italy) is a flood prone region, due to both its rough
orography and fast hydrologic response of most watersheds. During the rainy
season, intense rain affects the region, triggering floods and mass movements
that cause economic damage and fatalities. This work presents a
methodological approach to perform the comparative analysis of two events
affecting the same area at a distance of 15 years, by collecting all the
qualitative and quantitative features useful to describe both rain and
damage. The aim is to understand if similar meteorological events affecting
the same area can have different outcomes in terms of damage. The first event
occurred between 8 and 10 September 2000, damaged 109 out of 409
municipalities of the region and killed 13 people in a campsite due to a
flood. The second event, which occurred between 30 October and
1 November 2015, damaged 79 municipalities, and killed a man due to a flood.
The comparative analysis highlights that, despite the exceptionality of
triggering daily rain was higher in the 2015 event, the damage caused by the
2000 event to both infrastructures and belongings was higher, and it was
strongly increased due to the 13 flood victims. We concluded that, in the
2015 event, the management of pre-event phases, with the issuing of
meteorological alert, and the emergency management, with the preventive
evacuation of people in hazardous situations due to landslides or floods,
contributed to reduce the number of victims.
