RECOMMENDED ACTIONS
-------------------
Actions to protect human life and property will
vary within tsunami warning areas.

If you are in a tsunami warning area;

* Evacuate inland or to higher ground above and beyond
  designated tsunami hazard zones or move to an upper floor
  of a multi-story building depending on your situation.

* Move out of the water, off the beach, and away from
  harbors, marinas, breakwaters, bays and inlets.

* Be alert to and follow instructions from your local
  emergency officials because they may have more detailed or
  specific information for your location.

* If you feel a strong earthquake or extended ground rolling
  take immediate protective actions such as moving inland
  and/or uphill preferably by foot.

* Boat operators,
    * Where time and conditions permit, move your boat out to
      sea to a depth of at least 180 feet.

    * If at sea avoid entering shallow water, harbors,
      marinas, bays, and inlets to avoid floating and
      submerged debris and strong currents.

* Do not go to the shore to observe the tsunami.

* Do not return to the coast until local emergency officials
  indicate it is safe to do so.


IMPACTS
-------
Impacts will vary at different locations in the warning
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.

* 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.


ADDITIONAL INFORMATION AND NEXT UPDATE
--------------------------------------
* Refer to the internet site tsunami.gov for more information.

* Pacific coastal residents outside California, Oregon,
  Washington, British Columbia and Alaska should refer to the
  Pacific Tsunami Warning Center messages at tsunami.gov.

* This message will be updated within 30 minutes.
