Tonga Volcano.. terrifying 4' tidal wave hits Nuku'Alofa!

[Franziska]

Well, not sure what this means, but Tonga Internet seems to be gone:



Probably not a good sign.

Unlike wind waves, which are up-and-down surface waves, tsunami waves are back-and-forth displacement waves which are miles deep. That's a lot of water moving and when it hits an area only hundreds of feet deep or less, it just builds up. Crescent City is one of these areas, and it gets hit a lot.

BC news today.

A friend in Ventura, CA told me that nothing happened inside the Ventura West marina when the tidal wave supposedly hit the CA coastline. So Tofino and the rest of BC, much further away than SoCal, probably had minimal if any impact. Tonga - well that is ground zero, another matter altogether.

I can’t find anyone who noticed anything at all up here.

Probably took out the cable landing station. Though I’d have thought they’d have learned to have a second route after Intelsat 704 went dead.

Probably depends a bit on geography. I believe this was taken at the back of Santa Cruz harbor: https://video.twimg.com/ext_tw_video...bjp.mp4?tag=12

Your friend might have missed this in Ventura today

An aerial view shows capsized boats believed to be affected by the tsunami caused by an underwater volcano eruption on the island of Tonga at the South Pacific, in Muroto, Kochi prefecture, Japan


People look at a damaged boat in a marina in Tutukaka, New Zealand, on Sunday, after waves from the volcano eruption swept into the marina.

The last tsunami that arrived in Australia I think came from near Tonga as well. I was in the broadwater and the tide had turned about an hour earlier and was going out. Without any indication we realised that the tide was coming back in and it topped out a little higher than the actual high tide. It was just like normal tidal movement, perhaps a little faster.

I looked it up later to see what was written on it but the only information I could find said there was no measurable tsunami effect.

I think the news out of Tonga is going to get a whole lot worse and am rather disappointed in the Aus/NZ response - 'we will send a ship if they ask for one' ..

Some may remember the first reports out of Phuket 'Tsunami in Phuket, 12 feared dead'
I remember as my son was working in Krabi at the time.

The next thing will be disruptions to air travel due to that ash cloud.

My fear is that any of the videos that we are seeing may have been taken after the 1st blast. That eruption happened hours before the main eruption that can be seen from satellite footage.

The main eruption immediately knocked out all communication. I don't think that we are seeing video taken after the main event.

I spent 4 months in Tonga in 1984 and a year in 1994. There are areas that flood during extreme high tide. Most of the poorest population live in those areas and he homes are pretty flimsy at best.

Google is truly wonderful (not)..... Google tsunami damage specifying 2022 and Tonga, and you get lots of photos of destruction that date from earlier tsunamis. For example I saw a series of photos taken South American countries with horrific damage, and upon reading the details it became obvious that they were from an earlier tsunami. Drama is "in".

Scientists got their first look at Hunga Tonga Hunga Ha'apai post-eruption on Saturday when the EU's Sentinel-1A satellite flew overhead.

This spacecraft is a radar platform and can see through obscuring cloud and ash to the surface below.

It showed clearly that much of the crater rim that stood above the ocean waters had been destroyed - a testament to the ferocity of the blast.

Two people drowned off a beach in northern Peru, the local civil defense authority reported on Sunday, after unusually high waves were recorded in several coastal areas following Saturday's eruption of an underwater volcano in Tonga in the Pacific Ocean.

It arrived here in Kauai about 2 AM. No warning. Police reported to me that they only had an advisory.

It was easily 5-6 ft, and 4 ft above king tide level.

With my dock lines already set for king tides, I believe I got an advantage. Not that any more adjustment would have been a good idea. But there was definitely room for things to have been much worse.

Not an experience I will soon forget.

TIP.
When you hear a freight train coming, but you live on a boat, get off of it.
