| Zusammenfassung |
The use of high resolution hydrodynamic modelling to simulate the potential
effects of tsunami events can provide relevant information about the most
probable inundation areas. Moreover, the consideration of complementary data
such as the type of buildings, location of priority equipment, type of
roads, enables mapping of the most vulnerable zones, computing of the
expected damage on man-made structures, constrain of the definition of rescue
areas and escape routes, adaptation of emergency plans and proper evaluation
of the vulnerability associated with different areas and/or equipment.
Such an approach was used to evaluate the specific risks associated with a
potential occurrence of a tsunami event in the region of Setúbal
(Portugal), which was one of the areas most seriously affected by the 1755
tsunami.
In order to perform an evaluation of the hazard associated with the
occurrence of a similar event, high resolution wave propagation
simulations were performed considering different potential earthquake
sources with different magnitudes. Based on these simulations, detailed
inundation maps associated with the different events were produced. These
results were combined with the available information on the vulnerability of
the local infrastructures (building types, roads and streets
characteristics, priority buildings) in order to impose restrictions in the
production of high-scale potential damage maps, escape routes and emergency
routes maps. |
