| Zusammenfassung |
| Advances in the understanding and prediction of tsunami impacts allow the
development of risk reduction strategies for tsunami-prone areas. This paper
presents an integral framework for the formulation of tsunami evacuation
plans based on tsunami vulnerability assessment and evacuation modelling.
This framework considers (i) the hazard aspects (tsunami flooding
characteristics and arrival time), (ii) the characteristics of the exposed
area (people, shelters and road network), (iii) the current tsunami warning
procedures and timing, (iv) the time needed to evacuate the population, and
(v) the identification of measures to improve the evacuation process. The
proposed methodological framework aims to bridge between risk assessment and
risk management in terms of tsunami evacuation, as it allows for an
estimation of the degree of evacuation success of specific management
options, as well as for the classification and prioritization of the gathered
information, in order to formulate an optimal evacuation plan. The framework
has been applied to the El Salvador case study, demonstrating its
applicability to site-specific response times and population characteristics. |
