    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'!

    Oh boy. They just announced it's a WARNING, which means a Tsunami is IMMINENT.

    So far a 3.3 ft. wave was generated off the coast of Hokkaido.

    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. I forgot.

    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.
    I'm still here. Are you?

    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.
    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.

    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.

    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.

    That's my story, and I'm sticking to it.

    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?

    Update...the watch is being cancelled, per the PTWC.

    Not a wave, actually, but there still may be unusual currents and eddies. If there was any wave at all, even just one inch, it would still technically be a tsunami wave.

    KITV broke into programming again to say that the watch is cancelled and that beaches should remain clear due to possible "surges" now.

    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.
    The Discovery Channel still reruns the Indonesian Tsunami show frequently. The video footage of the water surging out and back in is the best example to learn about tsunami.

    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!
