Tsunami warning issued for morning of Jan 15, 2022

[Mark W.]

They are estimating 1-2.5ft waves on the Oregon coast. SO not as much as a decent storm.

Looks like I picked a bad day to go agate hunting on the coast. Sad.

My MIL is on Oahu. We've tried calling and texting. No response yet.
Hopefully it's just a warning and nothing come of it.

It looks more like a swelling of tides, not just one big wave. One report said Hawaii had seen some waves 3' high at 2:30am HST today. Hopefully she is doing well!

Seaside reports 2 to 3 foot waves!

Looks like it was pretty mild, and we might have dodged a bullet this time!

Good practice for the "Real One" if/when it happens!

They seem to be doing okay at the Pipeline!

They are alright.
My wife finally got a return call.

That pipeline picture is funny. We usually go visit them in the winter when it's big wave season. So I'm not surprised to see surfers out.

Tonga is the most affected area….

Quoted from Newsmax:

In Hawaii, the Pacific Tsunami Warning Center reported waves slamming ashore
from half a meter (a foot) in Nawiliwili, Kauai, to 80 centimeters (2.7 feet) in Hanalei.

Wow, a whole foot tall wave.
But it did slam ashore so..................

local news says "sunami" to arrive about 8:30 expect 1 - 3 ft. waves. maybe slightly larger. run for your lives!

It is not the height of the wave that matters in a tsunami. It is the amount of water behind it (wave length) it and how far inland it travels. They don't always stop on the beach like normal ocean waves. The farther inland it travels, particularly in populated areas, the more debris it tends to carry out to sea when the wave recedes. Then subsequent waves are a churning mass of water and debris which are particularly dangerous to anyone trapped in the water.

"Tsunamis have a small wave height offshore, and a very long wavelength (often hundreds of kilometres long, whereas normal ocean waves have a wavelength of only 30 or 40 metres),[34]which is why they generally pass unnoticed at sea, forming only a slight swell usually about 300 millimetres (12 in) above the normal sea surface. They grow in height when they reach shallower water, in a wave shoaling process described below. A tsunami can occur in any tidal state and even at low tide can still inundate coastal areas." from wikipedia.

Here is a good video from Japan showing how a very small in height wave becomes particularly destructive as the massive amount of water gets channeled up a river estuary.

Off shore bottom structures also effect both wave height and volume, greatly effecting the results! In Japan, the measured hight was far more then anything ever seen, but it's total volume didn't match the first three waves, it was only after the last of the waves hit that the flood followed! Some areas had humongous waves, but little volume, and other areas saw massive flooding with out the yuge waves!

It's very fascinating to see, and I have been studying it as much as I can!

DAMN! That at the start seemed like nothing but after a while was amazing to see how bad it gets.

Posted in other thread, repeated here.

It is not wave height that determines how destructive a tsunami is. It is wave length.

Get the fishing poles in the water, there's going to be some Salmon shot upriver!

Could you imagine something like that ripping up the Columbia and Willamette rivers, wiping out all the river communities plus a good portion of low level Portland.

Wow... thanks for sharing.
