Saturday, February 27, 2010 | Kristinn/ NWS

[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.

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.

I don't know how God will bring about the 'end times' exactly...

..but I suspect there will be multiple catastrophic events we can't even imagine.

No, they will bend around obstacles. Think of a rock in a pond, it creates a ring right, so it expands in a arc. When it comes upon shallow water it rises up, the water has to go somewhere. As it “hits” land the wave around that land slows down, making the wave appear to bend, and then it reflects back off of the land shelf. Think of a pylon in a pond, that wave hits the pylon, wraps around and reflects back off of it all at the same time.

Hawaii under tsunami warning

EWA BEACH, Hawaii — Hawaii braced Saturday for a potentially damaging tsunami, after a massive earthquake off Chile sent waves across the Pacific Ocean.

The Pacific Tsunami Warning Center issued a tsunami warning — its highest alert — for Hawaii, where incoming waves could cause damage along the coastlines across the island chain. A warning was also in effect for Guam, American Samoa and dozens of other Pacific islands.

The first waves were expected to arrive in Hawaii at 11:19 a.m. Saturday (4:19 p.m. EST).

A lower-grade tsunami advisory was in effect for the coast of California and an Alaskan coastal area from Kodiak to Attu islands. Authorities in Australia did not issue a warning, but asked residents to stay away from the coast.

The keep reporting Tsunami Warnings are going to be sounded at 11:19 am HST...

Good grief, I'd say the warning has already been "sounded"...

[rbmillerjr]

To give you an idea...go to youtube and search 1960 Chile Tsunami...one of the links is a simulation showing wave travel from that earthquake.

Scarey stuff.

[FromLori]

Thanks hennie pennie did you hear about a earthquake in chile?

I don’t see that my husband thought he heard that I’ll have to look for it

[Las Vegas Ron]

After giving a little more thought and seeing the map at 33, I can see that now.I remember an after shock in the Northridge quake, a big one, I was sitting down at a table looking out the window at the park across the street when it hit.

The ground actually looked like it became a body of water with swells going through it, most amazing thing I've ever seen.
