Title: Tonga volcano eruption
Post by: JosBaz on January 16, 2022, 03:13:14 PM
The recent explosive eruption of the volcano near Tonga, was even registered by my weatherstation in the Netherlands, at 16,000km distance.

The shockwave of the blast caused a 3hPa disturbance on the barometer graph. The 'second' wave (actually from the same blast but coming from the other direction) was also registered. Unbelievable.

There are several Japanese weather satellite videos in this Oregonian newspaper (https://www.oregonlive.com/weather/2022/01/video-of-tongan-volcano-eruption-from-space-live-cams-of-oregon-coast-waves.html) link. You can see the explosive (sonic?) shock wave in some of them.

Here is some better video and some narration from my favorite "Space" news source: "Hullo, I'm Scott Manley (https://www.youtube.com/watch?v=zoMRwyNhqJ4)" [lol]

JosBaz,

That is an amazing catch. I checked my WeatherCat pressure graph after seeing your post and, sure enough, the 1e drukgolf was on my graph too. Impressive!

Dear Jos, X-Air, Grand, and WeatherCat observers of the nature world.

Thanks Jos for sharing your very clear graph!  I also see the shock wave at Canebas weather station.  However, I couldn't manage to dial in the graph settings that display the shock wave as nicely as you do.  So for that I'm even more appreciative!

Cheers, Edouard  [cheers1]

Thanks for sharing Jos. You picked the correct word to describe this: unbelievable.
