Posted on 02/27/2010 4:37:11 AM PST by kristinn
The National Weather Service Pacific Tsunami Warning Center has issued a tsunami warning for Hawaii and a tsunami advisory for the West Coast of the United States.
A NWS spokesman on CNN says it is estimated the tsunami waves will be 10 to 15 feet high when they hit Hawaii. The tsunmi waves could last up to six hours.
Recent buoy reports of wave heights vary from 5 to 16 feet.
Latest statement on Hawaii:
TSUNAMI MESSAGE NUMBER 7
NWS PACIFIC TSUNAMI WARNING CENTER EWA BEACH HI
148 AM HST SAT FEB 27 2010
TO - CIVIL DEFENSE IN THE STATE OF HAWAII
SUBJECT - TSUNAMI WARNING SUPPLEMENT
A TSUNAMI WARNING CONTINUES IN EFFECT FOR THE STATE OF HAWAII.
A TSUNAMI HAS BEEN GENERATED THAT COULD CAUSE DAMAGE ALONG COASTLINES OF ALL ISLANDS IN THE STATE OF HAWAII. URGENT ACTION SHOULD BE TAKEN TO PROTECT LIVES AND PROPERTY.
A TSUNAMI IS A SERIES OF LONG OCEAN WAVES. EACH INDIVIDUAL WAVE CREST CAN LAST 5 TO 15 MINUTES OR MORE AND EXTENSIVELY FLOOD COASTAL AREAS. THE DANGER CAN CONTINUE FOR MANY HOURS AFTER THE INITIAL WAVE AS SUBSEQUENT WAVES ARRIVE. TSUNAMI WAVE HEIGHTS CANNOT BE PREDICTED AND THE FIRST WAVE MAY NOT BE THE LARGEST. TSUNAMI WAVES EFFICIENTLY WRAP AROUND ISLANDS. ALL SHORES ARE AT RISK NO MATTER WHICH DIRECTION THEY FACE. THE TROUGH OF A TSUNAMI WAVE MAY TEMPORARILY EXPOSE THE SEAFLOOR BUT THE AREA WILL QUICKLY FLOOD AGAIN. EXTREMELY STRONG AND UNUSUAL NEARSHORE CURRENTS CAN ACCOMPANY A TSUNAMI. DEBRIS PICKED UP AND CARRIED BY A TSUNAMI AMPLIFIES ITS DESTRUCTIVE POWER. SIMULTANEOUS HIGH TIDES OR HIGH SURF CAN SIGNIFICANTLY INCREASE THE TSUNAMI HAZARD.
THE ESTIMATED ARRIVAL TIME IN HAWAII OF THE FIRST TSUNAMI WAVE IS
1119 AM HST SAT 27 FEB 2010
The NWS has also issued a tsunami warning for most of the Pacific region:
TSUNAMI BULLETIN NUMBER 006

Here is a local report on the West Coast tsunami advisory:
A tsunami advisory has been issued for the California coast, including Del Norte County, following a massive 8.8-magnitude earthquake that struck off the central coast of Chile at 10:34 p.m. PST Friday.
The forecasted arrival time for Crescent City is 1:46 p.m. PST Saturday, however tsunamis can be dangerous for many hours after arrival, and the initial wave is not necessarily the largest, the West Coast and Alaska Tsunami Warning Center says.
THIS BULLETIN APPLIES TO AREAS WITHIN AND BORDERING THE PACIFIC OCEAN AND ADJACENT SEAS...EXCEPT ALASKA...BRITISH COLUMBIA... WASHINGTON...OREGON AND CALIFORNIA.

It's hard to imagine how those areas could possibly be affected.
Tsunami's travel a straight line, no?
How many freepers we have in Hawaii?
We need someone to do a ping and a soundoff.
I hope there is minimal wave action there and no damages.
I've seen some of them attempt to take on hurricane waves, usually very unsuccessfully, do I know there will be some fools try on these waves.
At first glance, 15-foot waves don't sound all that bad, but these won't be the slow rolling type waves usually encountered...these will be moving at a much higher rate of speed and packing a lot more punch as a result.
FReeper Fish Hawk lives near the coast on Maui...
If the ocean buoys are showing 5 to 16 foot waves, what’s the coastal impact wave going to be?
My dog is sleeping by the front door, guess I'm good to go here in Vegas.
Prayers up for all.
There was a huge earthquake in Japan last friday, the one now in Chile, and I am in between very very literally up here in Alaska on the Ring of Fire, and I have seen what the 1964 Good Friday quake did up here.
I lived in So. Cal for most of my life and have been through my share of quakes going back as far as the Sylmar quake in 1971 theough the Norhtridge quake in 1994 (lost my house in that one)
They're no fun, that's for sure.
After I read this thread, I did a quick search on 'quake' and 'earthquake' -- so of course I never located the MAIN Chile Earthquake messagethread, which currently is almost a thousand postings long.
I have NO idea why it didn't get into the sidebar, like this thread of Kristinn's did -- I don't really understand the mechanics of thread posting.
Here's the main thread with hundreds & hundreds of posts:
8.8 in Chile [Update at #277]
Don’t miss post no.33
Just kidding, no worries, I bet there is another 10 threads posted on this in the next hour.
Thanks for the link to the other thread :)
TB you better hurry with the donuts, there may be waves!
I just read on CNN that the tsunami is moving at 500 miles an hour!

Thanks Eye of Unk!
That is a fact, at that speed its an underwater shock wave, its when it approaches shallow land is when it builds, a ship at sea would feel a pulse but would probably not see much of a wave.
Well the shop is only 18 feet above high tide but at least the donut mill is on high ground. The north west had one of these mega quakes in 1700 and the geologist say they happen every 200 years?
