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,

* No tsunami observations are available to report.

PRELIMINARY EARTHQUAKE PARAMETERS - UPDATED
-------------------------------------------
* Magnitude 7.9
* Origin Time 0032 AKST Jan 23 2018
0132 PST Jan 23 2018
0932 UTC Jan 23 2018
* Coordinates 56.0 North 149.1 West
* Depth 12 miles
* Location 175 miles SE of Kodiak City, Alaska
360 miles S of Anchorage, Alaska

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.

If you are in a tsunami watch area;

* Prepare to take action and stay alert for further
information.

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.

OBSERVATIONS OF TSUNAMI ACTIVITY
--------------------------------
* No tsunami observations are available to report.

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.

If you are in a tsunami watch area;

* Prepare to take action and stay alert for further
information.

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.
