RECOMMENDED ACTIONS - UPDATED

-----------------------------

Actions to protect human life and property will

vary within tsunami advisory areas.



If you are in a tsunami advisory area;



* 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 advisory

areas.



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.



* 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.
