| dc.description.abstract | The continental coast of Ecuador is close to the subduction
of the Nazca plate and the South American
and corresponds to one of the most seismic areas in
the world. Of 58 tsunamis that have arrived in the
Ecuadorian coast, 19% turned out to be destructive.
In this paper the risk estimating probabilities according
to the source of generation is quantified. In the
continental coastline, 50% of destructive tsunamis are
near-field, 25% intermediate and 25% field far field.
In the Galapagos Islands, 75% of destructive tsunamis
are far-field, 25% of near-field and 0% intermediatefield.
A near-field tsunami has three times more likely
to be destructive in the continental coastline one
intermediate and far field. In Galapagos, the probability
that a destructive tsunami is independent of
the source of generation. If a distant source tsunami
is destructive Galapagos, there is a 28% chance to
be destructive in the continental coast. If a near-field
tsunami is destructive in the continental coast, then
it is very likely to also be in the archipelago. | |
