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.
(drukgolf is Dutch for shockwave) ;)

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.
