HNL And The Tsunami

The tsunami is supposed to arrive the Hawaiian islands around 11:20 HST. I see AA's DFW-HNL services are showing on time right now.

Is the HNL airfield high enough that there isn't a problem?

No, the HNL airport is a designated tsunami evacuation zone. The seabed of Mamala Bay just south of the airport is a fairly wide shelf and tsunamis have been known to wrap around the islands in the past.

Additionally, the reef runway (8R) obviously faces out to the SW; if a tsunami were to arrive, I'm assuming it'd come from the SE, meaning the leeward side of the island might be shielded somewhat. If a tsunami were to hit, 8R would probably absorb the hit for the rest of the field, including 8L.

Frankly, I'd be more concerned for French Polynesia, the Marshall Islands, etc.

Yes, the wave is expected to arrive in the Islands at 11:19am; civil defense authorities are going to sound evacuation sirens at 6am HST. Here's a map of evacuation zones on Oahu (HNL straddles zones 18 and 19):

No word on how this will affect HNL operations but from memory, most international and mainland arrivals and departures occur in the early morning, late afternoon and late evening. I'd assuming the respective airlines will have sufficient time to adjust based on any anticipated or actual interruptions in service.

If my geography is correct this would be Southwest side of Oahu in the Barbers Point region I also hear a T warning was put in place for American Samoa which is five air hours south of HNL

Latest is that if there indeed is a tsunami, wave heights will be no more than about 1.5 feet on Oahu and three feet on the Big Island of Hawaii. Let's hope people don't panic and the news services don't blow this way out of proportion.

I'm about 100 yards from the ocean just past Barber's Point at Ko Olina. I'm on the 15th floor so I'm good.

A similar incident in 1960 caused wave heights in Hilo Bay of almost 35 feet while most other places saw a max of "only" 17 feet. So if there is any cause for concern, it would be for the folks in Hilo. Luckily, they learned from that 1960 tsunami and did not rebuild the waterfront.

The state is well prepared so I'm hoping for the best.

Deepest sympathies to all those who perished in Chile.

It will be worth monitoring FlightAware to see if any airlines, corporate operators, or GA owners send up aircraft into holding patterns to protect them. I'd certainly do this if I ran an airline to protect those millions of dollars of assets, just in case, but I guess it wouldn't come cheap in regard to fuel, crew scheduling, etc.

Well it looks like lots of morning originators out of the West Coast are being delayed several hours - obviously so the airlines can monitor the situation there and hold back flights if something happens. As for the longer flights, it looks like AA, United, etc. are generally letting those go close to on-time. If this thing does hit Hawaii around 1120 local as predicted, that would give the airlines more than enough time to turn those planes around and send them back to LAX if need be.

God forbid.

I'm pulling for Hawaii - really hoping this thing stays at just a few-foot surge as some are predicting - it would be devastating if such an insanely wonderful place got hit hard.

90% of Hawaiian Airlines westcoast flights arrive between 1030 and noon.

Looking at flight tracker right now - all are still enroute - at least the SoCal ones.

Also Hickam AFB shares runways with HNL. Unless they move them to neighboring islands/Atolls. ATC I suspect is going to be busy.

Air Tahiti Nui' flight TN77 should be landing or has landed in HNL right now. It will stay there until the tsunami alert is lifted in PPT.

Thanks, the boats are starting to go back in the harbour, the Marquesas were hit by 4 waves highest was 4.13meters. The situation is fine in the Marquesas as they are very high islands, only the harbours were hit.
Couple of boats were damaged and witnesses were saying you could walk in the harbour as all the water was gone...

The leeward side is not immune. On a mostly circular island, as the waves wrap around the island, there can be an amplification of the waves were they come back together. I am not aware of whether there are limitations of this effect for larger islands, but on small round islands, some of the biggest damage has been observed on the leeward shores.

Operations at HNL should not be affected too much because only the Reef Runway (8R) is in the evacuation zone. Everything is still operating normally, but with caution since the first wave is expected to hit Hilo in 30 minutes.

That would be Lana'i Airport at 1308 ft MSL.
