| Zusammenfassung |
| Small amplitude tsunamis have impacted the French Mediterranean shore
(French Riviera) in the past centuries. Some caused casualties; others only generated
economic losses. While the North Atlantic and Mediterranean tsunami warning
system is being tested and is almost operational, no awareness and
preparedness measure is being implemented at a local scale. Evacuation is to
be considered along the French Riviera, but no plan exists within
communities. We show that various approaches can provide local stakeholders
with evacuation capacities assessments to develop adapted evacuation plans
through the case study of the Cannes–Antibes region. The complementarity
between large- and small-scale approaches is demonstrated with the use of
macro-simulators (graph-based) and micro-simulators (multi-agent-based) to select
shelter points and choose evacuation routes for pedestrians located on the
beach. The first one allows automatically selecting shelter points and
measuring and mapping their accessibility. The second one shows potential
congestion issues during pedestrian evacuations, and provides leads for the
improvement of urban environment. Temporal accessibility to shelters is
compared to potential local and distal tsunami travel times, showing a 40 min
deficit for an adequate crisis management in the first scenario, and
a 30 min surplus for the second one. |
