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.

“Hot link”
Federal Government is shut down. Ummm am I missing something? Website goes back to live today? All I’m getting is a spinning buffer wheel.
Spinning because so many are trying to check it.
People in various places still don’t know what will happen, eg
The Tsunami information page at NOAA is offline because of the government shutdown. That is going to piss some people off.
This is active, just slow.
Last update was more than an hour ago.
#tsunami has some dour predictions.

150am | A #TSUNAMI WATCH is in effect for the coast of Washington and Oregon. First waves may arrive around 510am, per the Tsunami Warning Center. Further details/updates can be found at (link: http://tsunami.gov) tsunami.gov or via NOAA weather radio... #orwx #wawx
Given the location, this would be a cold water tsunami, right? How does that, if at all, affect the speed at which it travels and its maximum wave height at landfall?
It looks good.
Seems the Alaska tsunamis were small, should not pose a danger to the more southern west coast areas.
My self. Perhaps the system is over-whelmed.

That could go over your ankles and should be considered extremely dangerous.
I would think those would be “essential” personnel??
my guess would be a antiquated or faulty system.
I guess it would depend on the coastal terrain and how the lead-in to the beach was shaped - sudden drop of close to shore adds up to faster/bigger surge when it piles up and long smooth transition would soften the blow.
Shutdown is over (until Feb 8)
Thats a lot of water moving. That “small” amount could raise havoc in an enclosed harbor.
So the epi-center was just 175 miles out?
