IMPACTS
-------
Impacts will vary at different locations in the warning and
in the advisory areas.
If you are in a tsunami warning area;
* A tsunami with damaging waves and powerful currents is
possible.
* Repeated coastal flooding is possible as waves arrive
onshore, move inland, and drain back into the ocean.
* Strong and unusual waves, currents and inland flooding
can drown or injure people and weaken or destroy structures
on land and in water.
* Water filled with floating or submerged debris that can
injure or kill people and weaken or destroy buildings and
bridges is possible.
* Strong and unusual currents and waves in harbors,
marinas, bays, and inlets may be especially
destructive.
If you are in a tsunami advisory area;
* A tsunami with strong waves and currents is possible.
* Waves and currents can drown or injure people who are
in the water.
* Currents at beaches and in harbors, marinas,
bays, and inlets may be especially dangerous.
If you are in a tsunami warning or advisory area;
* Some impacts may continue for many hours to days after
arrival of the first wave.
* The first wave may not be the largest so later waves may
be larger.
* Each wave may last 5 to 45 minutes as a wave encroaches
and recedes.
* Coasts facing all directions are threatened because the
waves can wrap around islands and headlands and into bays.
* Strong shaking or rolling of the ground indicates an
earthquake has occurred and a tsunami may be imminent.
* A rapidly receding or receded shoreline, unusual waves and
sounds, and strong currents are signs of a tsunami.
* The tsunami may appear as water moving rapidly out to sea,
a gentle rising tide like flood with no breaking wave,
as a series of breaking waves, or a frothy wall of water.
