The official warning reads the following:
RECOMMENDED ACTIONS
——————-
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
Authorities say to pay attention to local alerts if you're within the vicinity of the potential Tsunami path. Follow directions from the emergency medical responders in the area and remain calm as not to create widespread panic.
If you're in the region please stay safe and may God be with you.
