Alright, my self made air quality sensors for measured the pressure waves from the vulcano eruption in Tonga as well.


The kids and myself (indeed) were very stunned. We learned a lot.

@tpheine 👍 And both waves, too.
You proved the earth is round 😉

We weren't sure if this was the 2nd round of the wave. Thanks for explaining it to us!

The wave came once from the east and once from the west. I didn't thought about this myself, I heard it today on the radio. ☺️
The meteorologist spoke about a certain point inside the Sahara dessert where these waves would have hit at the same time, too. But there are no devices there, sadly.
