For scale, here it is from the original, uncropped satellite photos.

Look to bottom right, as terminator approaches.

Scary!

Was that a lucky shot or is the satellite there as a lookout? I'd love to see the underwater nuke tests for scale.

Footage of the tsunami making landfall.

See post above yours; there's a geostationary sat that caught it.

Oooooof that's bonkers!!!

How big is that carbon footprint then?

There's something very horrifying about a tsunami, real nightmare stuff.

Indeed, i think of all natural disasters it's the one i find most shocking. Possibly due to the amount of video that exists showing them.

It's kind of amazing and terrifying that technology means we can see this stuff unfolding almost in real time. Some pretty awful videos coming out of Tonga at the moment.

No idea so I looked it up. Best I can quickly find is an annual average of 360 million tonnes/year for global CO2 emissions from all volcanic activity.

So that's the same output as an Italy or UK.

That's impressive. I wonder how it compares to the biggest nuclear blast?

That’s amazing, you can even see the shockwave clearly! That must have been biblical at ground zero!

My daughter lives in a town in Sagami Bay Japan. It's where the Olympic sailing events were staged. It's about 4500 miles away from Tonga but they are on Tsunami alert. The pictures are amazing to watch and then you think of the force involved and people all around the south Pacific being impacted. Scary.

Pressure wave just passed the UK. My weather station caught it...

[Gareth79]

Same here!

[JonChalk]

Even my highly accurate, calibrated and well-maintained Netatmo picked it up;

The japanese one is the one that sticks in my mind, the height the water rose was just unreal.
Theres photos someplace with a fishing boat, a big one stranded on whats left of 3 storey building iirc.
As I recall there was a documentary done about it with the one video sequence showing the water rising and just keeps going, black and boiling over a concrete structure of some kind.
Just horrific to be caught up in all of that.

IIRC the Japan wave in 2011 reached just under 40m in some of the locations with the "right" geography. Not feet, meters. There is very little you can do to escape that. 120+ feet in a few minutes. Almost hard to imagine.

Whole pacific seaboard of the USA in tsunami alert now
