Check it out. It follows an 8.4 quake off of Japan.
Finally, an interesting weekend! yaaaay!
Being that the quake epicenter is (far) north-west of Hawaii, if a tsunami were to hit Hawaii shores, would it only affect shores here facing that direction? Or would it envelope the entire island?
You'll probably have abnormalities around the entire island shoreline but I would suspect the shores facing the direction of the incoming tsunami would be the ones that would face the waves.
I have absolutely no idea 'cept to wonder about the wrap-around effect like what's happening now with big No. Shore surf. Makaha is getting the wrap-around. Love it! Wouldn't love it if it was a tsunami, tho'! :eek:Quote:

The crawl at the bottom of the tv screen is predicting a 12:23am arrival if there is, in fact, a tsunami. It's still a Watch per breaking Channel 2 news. Guess I'll need to prepare to evacuate...just in case. No going to sleep 'til I feel certain it's safe. Shoot, I was hoping for an early night!
Security at my condo building is already going door to door to alert residents. They said if we have to evacuate, helicopters will do fly bys using a sound system to announce evacuation.
Man, my math is rusty. So the estimated arrival time in Honolulu is 10:41Z (UTC), which would be... 12:41 a.m. HST, right? Meaning the PTWC has to make a call on the sirens by 9 p.m. or so. Whew. Could be a very interesting night.
Dang! I can't find my Phone Book! What' the URL to find out if MWH is in A low area and if I have to evacuate. Cause if gotta...I gotta let my neighbors know. Many don't understand ENGLISH.:(
I think we are. :confused: I forgot.:o
Auntie Lynn
Ray Lowell at State Civil Defense is on KITV 4 now stating that if a tsunami hits Hawaii, that the waves have a potential to wrap around all coastal areas, even areas facing away from the quake origin.
Here is a link to a map with tsunami inundation zones around Hawaii:

If the maps are accurate MWH and areas above Kapiolani Blvd should be safe.
Mahalo Mel! MWH is safe.:)

Tsunami Bulletin #3 just posted. Same URL as previous updates, so I'm glad Mel copied the information from #2. Above, the "warning" applied to Russia, Japan, Marcus Is., Wake Is., Midway Is. and the N. Marianas. Now the areas under "warning" have grown to include Guam, Marshall Is., Taiwan, Yap, Pohnpei and Chuuk.Quote:
SEA LEVEL READINGS INDICATE A TSUNAMI WAS GENERATED. IT MAY HAVE BEEN DESTRUCTIVE ALONG COASTS NEAR THE EARTHQUAKE EPICENTER AND COULD ALSO BE A THREAT TO MORE DISTANT COASTS. AUTHORITIES SHOULD TAKE APPROPRIATE ACTION IN RESPONSE TO THIS POSSIBILITY. THIS CENTER WILL CONTINUE TO MONITOR SEA LEVEL DATA TO DETERMINE THE EXTENT AND SEVERITY OF THE THREAT.
Hawaii remains under "watch," along with the Philippines, Kosrae, Belau, Johnston Is., Indonesia, Kiribati, Nauru, Papua New Guinea, Howland-Baker, Palmyra Is., Solomon Is., Tuvalu, Vietnam, and Jarvis Is. I hope we and our other "watch" neighbors aren't promoted like some other locals have been.
During a commerical break KHNL suggested to tune in to the 9pm news on KFVE.
Latest updates from the Pacific Tsunami Warning Center are posted at http://www.prh.noaa.gov/ptwc/bulletins.htm . Under the heading of "Hawai`i" at the top of the page, click on the link that says "Latest".
As others have said, we're still under a tsunami "watch" and not a "warning", but yes, that can change.
The safest place to be, were there to be a warning and strong signs of an imminent tsunami, would be on a boat, offshore. Remember, tsunami are not waves on the ocean surface -- they're pressure waves under the surface, until they hit shallow water. (The pressure waves can move at speeds up to 600mph.) At sea, the tsunami may only be an inch or so high, but develop into 30' or far far larger once it hits shallow water.
Ergo, safest to be on a boat offshore. The mainland shorelines have a shelf that slowly drops off to deeper water, but here, of course, we have extremely deep water very close to shore. To be safe, on the mainland you'd have to go many miles offshore, but not so much so here.
It's standard procedure in the event of a tsunami warning for Navy and Coast Guard ships to put to sea for that very reason. Anybody have a view of Pearl Harbor and/or Sand Island? If there's a lot of activity of ships leaving harbor, we should pay closer attention.
I saw the 9pm item on KFVE. Still analyzing the data. Interesting that they showed the activity in the PTWC. Nothing frantic, but obviously busy.
I'm guessing we're safe. But Mother Nature can be a fickle wench.
KFVE reported the tsunami is less than half of the original 3' report. A 10cm wave surge was reported but "we're still not out of the woods yet"!
I'm confused, tho'! There's already a large swell happening on north and west shores. So, if, say, a 3' tsunami does hit us, does that 3' swell get swallowed up by the already large swell or does the swell increase by 3'? Or, is the surge the biggest worry? :confused:
Update...the watch is being cancelled, per the PTWC.
Thanks, LN.Quote:

Thanks to everyone for their info. I have family in one of the evacuation zones. You guys are much faster than the Internet news sources.Quote:

KHNL paused Law & Order to report the cancellation of the watch. Anyway does anyone remember this event of November 2006?
True. Interestingly, the safest place on the shoreline is Kaneohe Bay, being the only place in Hawai`i that has a barrier reef. A large tsunami would cause some water to recede out of the bay, then rush back in, causing a surge, but not a wave. The situation would be even better if it happened at high tide.Quote:

Shoots. I wish I were at my mom's place in Hawaii Kai right now with my camera.
She said when the tidal surge hit from the quake in the Kuril islands in November, the canal behind her house, which opens at Moanalua Bay, had a series of waves strong enough that they actually pitched over! Normally this canal is flat as a lake! The house is approximately 1000' away from the bay. The canal surge might happen again around midnight tonight. That would make interesting video footage. Hopefully some tourists in Waikiki beachfront hotels will have their cameras out.
Scary though. Sure hope those DART buoy readings are correct!
Me too! I plan to stay up to watch the anticipated ocean activity and will keep my street clothes on and my purse and computer by the door. Ha! As if I'd have time at that point to flee the scene! :eek: Shoot...I wish it was a full moon night. The ocean's only 25 feet away and it's so dark I really can't see it.Quote:

Yikes. For sure Auntie's MWH would be in the inundation zone! It appears all of Oahu would be wiped out.Quote:

Tutusue, I figured out dat too...but neva say anting cause i neva like make myself scared.:eek: It's almost time. I can go moemoe. Are you able to see any action out there? It makes me woder what would happen to the the many Homeless Beach people and their families? Sad ~ totally heartbreaking.Quote:

HAHAHAHAHAHAHA
Lyjnnie
btw: Again, wat would the Homeless Popilation do if a damaging one strike our islands? I want to know if a plan is in place. Is it's public record which is allowed to be seen by the Public? Where does one go to in an event of a catastrophe occurring in hopes to help our fellow men and women in our community?

Tsunami watch surges Hawaii fears
An earthquake off Japan leaves the state on alert for three hours before word that no destructive wave is expected
Star-Bulletin staff
"Hawaii was under a tsunami watch for three hours last night after an estimated 8.2-magnitude earthquake struck east of the Kuril Islands off Japan.
City officials were concerned about homeless people living on Leeward Coast beaches and were making shelters at Nanakuli and Waianae Intermediate schools available if needed.
Tsunami waves -- generated by earthquakes -- are often barely noticeable in the ocean but can rise to great heights once they arrive at shore."
Once again, Mahalo fellow HT Members, Mel, Glen M., PZ, Pomai, Mike, Helen, tutusue and LikaNui for the information you contributed.
Mahalo,
Auntie Lynn
well, there was some wave activity last night. We bugged out our office, being that it is approx 100 yards from shoreline. Some coral and rocks got tossed about 50ft past normal water level, but no damage, thankfully. Count the moon on quarter as a blessing, because the surges hit at high tide, which was 12:45am last night. If it was a new/full moon, the tide would have been worse.
With all due respect, Auntie, last night woulda been the worst time to "test and fix" any glitches. With the watch in effect, the breaking news stories and the constant warning crawl along the bottom of the TV screen, testing the sirens woulda caused panic. The last test was on Jan. 1 or 2...can't remember. Hopefully, if they found problems with any of the sirens at that time they woulda fixed 'em by now. :rolleyes:Quote:

The small bay in front of my condo was churning but I couldn't tell what was large swell activity and what was tsunami surge activity. It was just too dark. And, yes, a high tide at the same time which, had there been a large tsunami, would've exacerbated the event.Quote:

Typically on Friday night at this time, when a 1 block span would have more than 100 people on the sidewalks, was down to less than 10 people or less in the same given area. Even the street performers weren't around, except 1 that I seen. Hardly any cars were on the blvd. and Police patrol car presence was light, which was a bit surprising.
Duke's in the Outrigger on the beach, which is supposed to be open until 1am (and busy all the way until then), was closed.
Waikiki hotels must have warned their guests to stay in their rooms, and even though the watch was lifted by 9:30pm, perhaps our visitors remained cautious and stayed indoors.
Kuhio Ave. had more people out and about, but definately less than a "normal" Friday night. As I walked home, thoughts of "what if it still comes" haunted my mind, having visions of a flood of sea water rushing down Seaside Ave. :eek:
If a revised Tsunami alert guideline takes effect, which lowers the quake scale to 6.7, plan on seeing more scares like this here. Still, better warned (scared) and safe, than uninformed and dead like those lost in Indonesia. Sure was a wake-up call.
So I hear the media hyped it up wrong indicating it was a warning (albeit local only to Japan) instead of a watch.
With businesses suffering because of erroneous reporting, were businesses damaged financially enough to sue the media that reported it or at least the source of the report?
Hmmmm....
NGC (the National Geographic Chennel) is airing a tsunami program tonight at 7pm. Not sure if it's the one about the Indonesian tsunami, but. Channel 73 (analog cable) or channel 347 (digital cable).
Certainly can't sue the media, since the mistake was made by the National Weather Service. The NWS says one of thier staff hit the wrong button "by accident".Quote:

I have an Aussie assistant and you'd think, at this point, I could tell an Aussie accent from a British accent...but...I can't! :o I can't smell or taste, either! :D
I didn't realize Aussies smelled and tasted different from Brits. :DQuote:
