The satellite imagery is incredible -- you can see atmospheric waves traveling hundreds of kilometers:

Edited comment: originally linked to the wrong satellite imagery (from a separate eruption several hours ago). The discussion in this link is still informative, but not current:

Here's the Himawari-8 satellite viewer, centred on the eruption.

For anyone wanting to see the same shockwave as is linked here in video form, a BBC article[0] has a it embedded. The Himawari viewer works well for stills but makes the effect over time a bit harder to appreciate.

Seriously fuck the BBC and their Cookie Consent prompt, do they really expect me to manually untick every single vendor?

No, they expect you to give up and accept them.

The worst one I ever saw was where above the fold items were unchecked, but the below the fold items were checked where you couldn’t see them.

You could use Firefox and a cookie-handler plug-in.

Yeah I just browse with a profile that deletes all cookies and history when I close the browser. Then just accept or dismiss all those stupid cookie consent popups.

I've seen many of consent forms mention tracking beyond cookies and cross-devices.

Are you sure that by accepting you aren't just accepting legally to continue to be tracked with all other means?

If true, then deleting cookies only cause them to ask again next time, but you're still fully tracked.

See https://www.kompyte.com/blog/5-ways-to-identify-your-users-w... (just found it) for examples of tracking without cookies.

They don't have it on mobile yet, though you can use the "I don't care about cookies" UBlock filterlist

More like "they had, but decided to remove". Firefox on Android used to support any extensions, but they cut that down. You can still get the functionality in browsers like Icecatmobile, though.

If you mean the old XUL extensions with zero security? I think that transition was worth losing some extensions due to the more strict sandboxing.

Alexander Hanff is trying to sort that: https://twitter.com/alexanderhanff/status/147830653943796940...

How about just not using their website is it is so annoying? The more audience they lose, the more apt they C we’ll be to change it.

That man is a moron. A tweet to a large organization's twitter handle is not a formal complaint.

I guess sending in a letter isn't as good for social media engagement, though.

I'm curious as to what you see (I'm in the UK so there are very strict legal requirements that the BBC don't show ads so my page will be different to yours) for me the cookie prompt is at the top and pushes the content down a little but I can ignore it and see everything. That meets gdpr requirements as I can still do what I want and unless I tick OK nothing should be set.

That sounds like a different experience to what we get in the UK - one cookie prompt and you're good to go for many months (at least).

Could be the BBC's fault, possibly due to in-country legalese though?

Use incognito, or Firefox + Multi-account Container + Temporary containers

uBlock Origin + EasyList Cookies or Fanboy Annoyances.

This is FANTASTIC! Thank you so much for sharing these links. Kids loved this, as we had just learned about similar volcanic eruptions through a recent Nat Geo magazine.

I think this might be the first satellite imagery I've seen that caught the color change in the clouds at sunset..

So it looks like the eruption happened right at dusk. For some reason that feels to me like that would make it worse for the people.

Yeah - the timelapse of the terminator showing darkness descending suggests it's was a rough night.

Himawari-8 footage is excellent. That shockwave is gigantic. Thanks for the link.

Really makes you think about how cool satellites have gotten. After some googling, I learned Himawari is a Japanese weather satellite:

Video from Space is equally stunning: https://twitter.com/wonderofscience/status/14822800417993850...

That's the best one. Incredible. To imagine that Tonga is practically right at ground zero. Anyone know how this measures in megatonnes?

Here’s video with the sound of the eruption (loudest to faintest):

100-160 Mt i saw rumored on Twitter.

Is my wikipedia-ing correct? Krakatoa was 200 Mt?

Are the Tongans okay?

No injuries reported, but communication is intermittent.

https://news.yahoo.com/tonga-issues-tsunami-warning-undersea...

> There were no immediate reports of injuries or the extent of the damage because all internet connectivity with Tonga was lost at about 6:40 p.m. local time — about 10 minutes after problems began, said Doug Madory, director of internet analysis for the network intelligence firm Kentik.

> Tonga gets its internet via an undersea cable from Suva, Fiji, which presumably was damaged. The company that manages that connection, Southern Cross Cable Network, could not immediately be reached for comment.

There are social media posts of the tsunami though which I believe are from Tonga. So folks at the shoreline were presumably fine enough to record and post video somehow.

I’d be worried about anyone on an airplane near there, but I guess it’s not a highly trafficked route.

>I’d be worried about anyone on an airplane near there, but I guess it’s not a highly trafficked route.

I was curious whether Fua'amotu International Airport is a stop on flights going elsewhere but I wasn't able to come up with a good search. It sounds like it could be:

"The air field was constructed by Seabees of the 1st Construction Battalion with assistance and labor of the U. S. Army 147th Infantry Regiment. It was intended as a World War II heavy bomber field, and had three coral-surfaced runways. In the late 1970s, it was expanded to permit jet aircraft to use the runways. Fuaʻamotu is now suitable for up to Boeing 767 size aircraft, but remains closed to larger jets (e.g. Boeing 747s)."

Today's aircraft can easily handle transpacific flights, and Tonga is in the Southern Hemisphere close to the equator so even Southern Hemisphere flights would likely avoid it.

It's basically just Australia and New Zealand to Hawaii and North America, and Pacific Islands east of Tonga. As well as any inter-Oceanic flights that happen to pass it.

I wonder how these social media posts were being uploaded due to a loss of internet connectivity. Satellite internet, or has internet been restored already?

Last time the undersea fibre optic cables (international and local) were broken (2019-2020) [0] a Kacific [1] K-band satellite emergency link was installed for and by the Tonga ISP EziNet [2] and others.

(the 2019 break was caused by a Turkish oil tanker prematurely dropping anchor in a restricted zone [3])

"DS Venture Ltd (DSV) was the owner of the Duzgit Venture. On 20 January 2019, as the vessel approached the Port of Nuku'alofa, its starboard anchor and chain were prematurely released from their housing. As the anchor and chain were winched back in, they caught and damaged a cable. The cable was one of two undersea communications cables owned by Tonga Cable Ltd (TCL) connecting Nuku'alofa, Ha'apai, and Vava'u with Fiji. As a result of damage to the cable, Tonga was without cable telecommunications for almost three weeks. "

If the undersea cable was damaged I doubt it was repaired that quickly. I’m guessing satellite Internet.

Thank you for your incredible link collection.

404ing for the first link

Oh no! Both links are a 404 now. Why didn't I save them :(

https://www.star.nesdis.noaa.gov/goes/sector_band.php?sat=G1...

https://rammb.cira.colostate.edu/ramsdis/online/loop.asp?dat...

(Same links, with time windows that go further back)

Here's alternate versions with 24-hour long windows (not ideal), because I haven't figured out how to link timestamps in the URL parameters of satellite loops, so they are shifting forwards in time. (I'm sure someone else will figure out a better solution: I've given up).

There was one yesterday and a bigger one 3-4 hours ago

And potentially more eruptions after the big one:

They are evacuating Lord Howe Island.
