* Magnitude 8.7
* Origin Time 1525 AKDT Jul 29 2025
1625 PDT Jul 29 2025
2325 UTC Jul 29 2025
* Coordinates 52.2 North 160.0 East
* Depth 46 miles
* Location 315 miles SW of Bering I., Komandorski
80 miles SE of Petropavlovsk, Kamchatka
RECOMMENDED ACTIONS - UPDATED
-----------------------------
Actions to protect human life and property will
vary within tsunami warning areas and within tsunami
advisory 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.
If you are in a tsunami warning or 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 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.
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 60 minutes.

* 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 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.
ADDITIONAL INFORMATION AND NEXT UPDATE

* Refer to the internet site tsunami.gov for more information.
