Tsunami Sirens in Hawaii

[almdoc]

According to the weather channel Hawaii has about 7 hours( it's 0945 EST) before the possibility of a tsunami from the 8.8 earthquake on the western side of Chili. I hope the sirens are up to snuff. Looks like our beloved Thunderbolts might get a workout today.

Local Hawaii TV is says Civil Defense sirens will sound at 6:00 a.m. local time (which evidently is 8:00 a.m. pacific time). All coastlines are part of the evacuation. Looks like people are already starting to get out of there.

Weather channel just said that around 1100 EST the tsunami sirens will be sounded in Hawaii. That is very soon.

[Hacksaw]

Hawaii is telling everyone to get inland.

There's tsunami concerns for all California beaches.

And some concerns for the Pacific NW coast into Canada.

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

MESSAGES WILL BE ISSUED HOURLY OR SOONER AS CONDITIONS WARRANT.

They had a Tbolt 1000T in the back round on a live call from a Hawaii News station to one of our area TV stations. Also, CNN had a clip of a DSA going off.

Live stream: mms://a642.l7309558641.c73095.n.lm.akamaistream.net/D/642/73095/v0001/reflector:58641 - this station has a reporter that is right next to a DSA. Last time it sounded, it sounded like one of its speakers were bad - had a warble tone to it.

Wow, go figure I'd get my news from the Siren Board. I have a friend on the visiting the big island. This should be quite the surprise for her, I'm almost envious
