Evacuations on Easter Island, and Tsunami Warning Sirens going off in Hawaii according to MSNBC!!!

*******************************************************************************

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.

1. Fixed Link To NOAA Tsunami Center Above...

:kick:

[wtmusic]

4. I thought they traveled at ±500mph

Wouldn't they have already hit? :shrug:

[gristy]

8. Yeah, 500mph is about right. -500mph, I don't think so.

:)

[wtmusic]

13. *smack*

Thanks, I...needed that

:banghead:

[malaise]

2. The good news is that Robinson Crusoe island was

not devastated although that island was hit with 3 meter waves. Easter island is next.
Stay alert peeps

[mix]

3. I wonder how it will affect people at sea. nt

[nadinbrzezinski]

10. My hubby told me that at sea

you might feel a little more... if submerged (US Navy), otherwise in the middle of the ocean it is barely noticeable.

[malaise]

As long as they are away from the coast they'll be fine

Remember the documentary about the great 1883 eruption of Kracatoa and the captain who took his ship further out to sea.

--
There was a 7.7ft tsunami on a section of the Chilean coast - that's relatively small but the tsunami's impact should be felt more in the West

[Dappleganger]

14. Fascinating link, thanks! nt

[malaise]

17. I love the pics at the link

Kracatoa always fascinated me and baby Kracatoa is just as fascinating.
I bookmarked this last year. :hi:

[Dappleganger]

18. Same here, but haven't kept up with baby Kracatoa as much.

As a huge history buff I enjoyed reading different people's accounts of what happened and in particular the world-wide weather changes it caused.

[pipi_k]

11. A curious thing about tsunami...

is that, out at sea, they're hardly noticeable. They can look like a tiny ripple on the surface of the ocean. A boat floating on the ocean would probably not even notice. It's when they hit the shallower waters that all hell breaks loose.

[tinrobot]

12. They would hardly even notice it.

If normal waves are like bumps in the road, a tsunami is like the bumpy road going over a hill. You notice yourself rising, then falling, but you'd still mostly feel the smaller bumps.

Tsunamis really only express themselves when they hit land. So, instead of the small bumps hitting the shore, the hill hits the shore.

[slackmaster]

23. Not much

Just a little bump if you are in deep water.

[tinrobot]

5. Time to go surfing.

Seriously, I hope everyone gets to high ground in time.

[Dappleganger]

15. Surfers and wave-gawkers can be a huge problem...

here in FL they scramble to the beaches as soon as the winds pick up so they can ride dangerously. Wouldn't surprise me if the Pacific loses some people to tsunamis like that as well.

[gristy]

6. Entire west coast of N America too. All the way up to Alaska.

[Odin2005]

7. YIKES!

16. Wow... They Just Closed The Airport In Hilo...

Airport in Honolulu is staying open for now...

:wow:

[nadinbrzezinski]

20. Honolulu Int WILL stay open as long as possilbe

it is also Hickam AF Base... so they will keep that open as long as they can to bring emergency gear in as long as they can.

The fleet most be leaving though.

[Selatius]

29. As long as the fleet is in open waters, the tsunami will simply pass underneath the ships.

If you're out in the open ocean, the only clue you might get that a tsunami is passing by is that you will see a swell move toward you and pass underneath, lifting up your ship temporarily.

[nadinbrzezinski]

36. Why they are scrambling

24. It is less than a foot in Mexico

readying the Acapulco, Marquesas and other reports.

So hopefully it will have dissipated and will be minor.

Now OB in San Diego will get flooded... between this and the storm surge... it ALWAYS gets flooded.

[slackmaster]

26. My ex lives in IB. I just left her a voice mail in case she's not paying attention

Expected height for La Jolla is .8 meter.

[nadinbrzezinski]

27. Without smorm surge

that be nothing

[WillyT]

30. Um...

I certainly hope you are correct, but this concerns me...

<snip>

While everyday wind waves have a wavelength (from crest to crest) of about 100 metres (330 ft) and a height of roughly 2 metres (6.6 ft), a tsunami in the deep ocean has a wavelength of about 200 kilometres (120 mi). Such a wave travels at well over 800 kilometres per hour (500 mph), but due to the enormous wavelength the wave oscillation at any given point takes 20 or 30 minutes to complete a cycle and has an amplitude of only about 1 metre (3.3 ft).<10> This makes tsunamis difficult to detect over deep water. Ships rarely notice their passage.

As the tsunami approaches the coast and the waters become shallow, wave shoaling compresses the wave and its velocity slows below 80 kilometres per hour (50 mph). Its wavelength diminishes to less than 20 kilometres (12 mi) and its amplitude grows enormously, producing a distinctly visible wave. Since the wave still has such a long wavelength, the tsunami may take minutes to reach full height. Except for the very largest tsunamis, the approaching wave does not break (like a surf break), but rather appears like a fast moving tidal bore.<11> Open bays and coastlines adjacent to very deep water may shape the tsunami further into a step-like wave with a steep-breaking front.



When the tsunami's wave peak reaches the shore, the resulting temporary rise in sea level is termed run up. Run up is measured in metres above a reference sea level.<11> A large tsunami may feature multiple waves arriving over a period of hours, with significant time between the wave crests. The first wave to reach the shore may not have the highest run up.<12>

IOW - A one foot, or a one meter wave, is not necessarily still one foot, or one meter when it comes on shore. Am I getting this right???

:shrug:

[nadinbrzezinski]

37. They detected 0.98 meters in Acapulco Mexico

that is inside the Bay... so that might make a difference.

Granted, that is a high wave for the inside the bay.

The US Navy is scrambling in both Hawaii and SD... (and if they are also scrambling Wibley Island they won't tell, SSNs there)

There has to be a reason for that.

Funny, they have sirens installed all along the coast in from LA to SD now, not that most Californians would know what that means.

[4lbs]

21. As far as I see, only the coast of Chile has the RED, or HIGH Severity warning. Every other place,

including Hawaii, has a GREEN, or LOW Severity warning.

That means that the 'damage' to Hawaii's coastline would be no worse than the 15-foot waves that crash on Hawaii's beaches during a normal rainstorm.

Besides, Hawaii is 3000+ miles away from the epicenter of that Chile quake.

By comparison, remember the 2004 Indian Ocean Earthquake and Tsunami? That quake was about a 9.1, and the coast of India that was within 500 miles of the epicenter, was hit with 40-foot waves that caused flooding several miles inland. However, the coast of Africa was 3000 miles away, and only got 15-foot waves, and no flooding past the immediate beach area.

33. If He Keeps Posting, Let Us Know Please !!!

MSNBC said earlier that in Oahu, they are telling people to go to the 3rd floor or higher in the high-rise hotels there.

39. Wave up to 13 ft in the Marquesas

Large waves are reported to have struck Chile's Juan Fernandez island group, reaching halfway into one inhabited area. Three people there are missing, local media say. Two aid ships are reported to be on their way.

Part of the Marquesas Islands in French Polynesia were hit by a 4m (13ft) wave, but no casualties were reported, AFP news agency said.
