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:
BULLETIN
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.
SNIP
EVALUATION
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
PACIFIC TSUNAMI WARNING CENTER/NOAA/NWS
ISSUED AT 1147Z 27 FEB 2010
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 you people’s fault. Your campaign against the media has left them without the resources to have bureaus in nearly as many places as they used to. Just the fault of the pajama people and their claiming to be “journalists.”
F=MA force equals mass times acceleration
PER TWITTER:
Tsunami is travelling at 700KPH+ in the open ocean.
thanks
Yep. Time derivative of momentum.

Sorry Sir Isaac - acceleration.
Well, Karl Rove is in Hawaii...heh,heh,heh ;-)
1st wave predicted in about 10 minutes.
Yikes, I am hearing 35 ft Waves????
Watching the webcam...
We are dealing with wave frequency. Speed is the speed of sound under water, water temperature, depth and salinity.
The faster that the depth increases, the more energy the wave will deliver. Hydrostatic pressure and energy are the two prevalent forces, based on the weight and height of Salt water. Velocity is relative to wave frequency..
CNN reporter just got a little upset while interviewing a Tsunami/ Quake expert. The expert was making good points and the reporter wanted a different answer.
Twitter says CNN is reporting a 27 foot drop in the ocean...
This is surreal just waiting around for this thing to hit.
Wow, where was that? Off the coast of HI?
HAwaii County PD stressing that like the Indian Ocean TSunami, the first wave may NOT be the largest to come.
The CNN reporter has been treating the expert like this all day. Very undermining and impatient.
