Additional guidance from US Tsunami Warning System:

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.
