Zusammenfassung |
We present a first detailed tsunami risk assessment for the city of Messina
where one of the most destructive tsunami inundations of the last centuries
occurred in 1908. In the tsunami hazard evaluation, probabilities are
calculated through a new general modular Bayesian tool for Probability
Tsunami Hazard Assessment. The estimation of losses of persons and buildings
takes into account data collected directly or supplied by: (i) the Italian
National Institute of Statistics that provides information on the
population, on buildings and on many relevant social aspects; (ii) the
Italian National Territory Agency that provides updated economic values of
the buildings on the basis of their typology (residential, commercial,
industrial) and location (streets); and (iii) the Train and Port
Authorities. For human beings, a factor of time exposition is introduced and
calculated in terms of hours per day in different places (private and
public) and in terms of seasons, considering that some factors like the
number of tourists can vary by one order of magnitude from January to
August. Since the tsunami risk is a function of the run-up levels along the
coast, a variable tsunami risk zone is defined as the area along the Messina
coast where tsunami inundations may occur. |
