GOES GeoColor channel (infrared at night) ~3hr time lapse movie, frame updates every 10 minutes with about 1/2 hour lag. Looks like it'll be a while before it clears out even if there are no further eruptions...

We're getting tsunami warnings on the US west coast...

Internet traffic dropped to zero about an hour after the eruption. No contact with Tonga since (+12 hours & counting)...

It's that visible from space, cripes. I believe we have an Orion on standby pending the local atmospheric conditions calming down, TBC what further assistance will be deployed, press conference in 2 hours.

Good coverage ...one from a boat and the other from a 1,000 km away where you can hear the bang.

Via UK Met. Office [/url=https://twitter.com/metoffice/status/1482605906659622914]tweet[/url]:
Our atmosphere acts as a fluid, like dropping a pebble in a still pond and seeing the ripples.

A UK pressure trace for the past 24 hours shows how our atmosphere continues to see those ripples since the first pressure wave from the Tonga eruption arrived on Saturday evening.

Tweeter William Churchill plots cloud to ground lightning strikes from GOES data and associated with the eruption here:

Tweet from the weather service in American Samoa about 1 hour ago
There has been another eruption from the volcano in Tonga.

However, based on the latest information, there is NO TSUNAMI THREAT for American Samoa at this time.
Because this volcano remains active, please stay tuned for further updates.

My quick scans of the GEO-Sat images show a much smaller plume than the last one but I'll wait and see... :dunno:

Not on topic, just a cool story, but my first boss was from Tonga and he was the best boss I ever had as he was very good with people. I idealized how I would live there - coconuts, beaches, chill - but I was just dumb and ignorant.

Pretty sure this is the result of the earth expanding and adding mass. :shifty:

I was chatting about this to my SO, and she suggested that some will use the idea of volcanic winter to suggest that setting off a few nukes can have a positive impact on climate change. Of course, there are some issues...

Volcanic winter is short-lived, but the extra carbon in the atmosphere is considerably less so, so the net result will be an increase in warming, albeit by not such a large amount as a naïve estimate might suppose. A nuclear explosion has the added disadvantage of spreading free neutrons into the atmosphere, and we all know what the product is when nitrogen gets bombarded by neutrons, because that's where pretty much all the 14C on the planet comes from.

Does this means that when the alien archeologists discover our fallen civilization in the next few thousand years, they will have incorrectly dated our bones because of the excess of C14?

Indeed. :lol:

As a somewhat amusing aside, it should be possible in principle to pinpoint fairly accurately the locations of any bombs dropped, as anomalously young ages for bones should propagate concentrically from the epicentre, with the highest levels of 14C in the bones closest to ground zero.

And that is why you can't trust radio-carbon dating. Take that atheists!

As an aside, atomic testing not only screwed up C14 dating post 1945, but also created a market for Low-Background Steel that resulted in the looting of some war graves. Talk about unintended consequences.

Sadly the first confirmed fatality as a result of the tsunami has been announced - Pacific volcano: Body of British woman found in Tonga, says brother (BBC).
