Scott Manley has done an excellent summary video of the Tongan volcano, much of the science and history of it as well as the effects thousands of miles away. The area around the volcano had completely reformed in the last ten years. He has collected some great footage together.

It’s interesting watching air pressure waves travel across Japan and the USA.

In the last 24 hours we’ve seen a huge explosive volcanic eruption from the Tongan island of Hunga Tonga-Hunga Ha’apai – the blast is so large it’s easily visible from multiple satellites in geostationary orbit, tens of thousands of miles up.

The blast sent a soundwave around the world which is still being measured and the resulting tsunami caused flooding around the Pacific Ocean.

The CliffMass weather blog noted that the pressure wave hit Seattle at 4:30AM local time, so the air pressure spike took 8.5 hours to cross the Pacific at about 664miles per hour. h/t WattsUp

Sending best wishes for the poor people of Tonga.

Will this make a difference to global temperatures, or will just it provide a convenient excuse for cooling that may be on the way in 2022 anyhow?
