Research on
Extreme Natural Hazards: Tsunami
Hazard evaluation:
■ For 2011 Tohoku Earthquake, JNES
developed a tsunami source model.
By generalizing this model, S/NRA/R is
developing a probabilistic tsunami
hazard evaluation method.
Fragility data accumulation:
S/NRA/R is conducting the tests on
impact on seawall due to tsunami.

■ The tests are being
done at PARI (Port and
Airport Research Institute).
The data obtained are
expected to be used
for updating the
review guides for
design against tsunami.View entire presentation
