Description:
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 Probabil-
ity 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 (res-
idential, commercial, industrial) and location (streets); and
(iii) the Train and Port Authorities. For human beings, a fac-
tor 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.
