Shockwave from volcano

(1/9) > >>

Don't know if this really belongs here as its not exactly weather but...

A bit over two hours after the volcano erupted in Tonga, around 1986km from Port Charles according to Google Maps. I never thought something like this would be picked up by a personal weather station before.

Zoomed view of just the pressure surge:

News is saying quite a few people even here in New Zealand over 2000km away heard the eruption (or its shockwave) as well.

Not as dramatic but I also saw a blip in Northern Idaho.

Waiting to see if Europe gets anything.

Thanks for starting the thread!

The same here in eastern Washington. Scanning WU you can see the blip and compare times with other stations. Very interesting.
