A number of folk on the UK Meteor Network have their own weather systems, and several of them have reported detecting barometric pressure changes caused by the shockwave from the volcanic explosion. The Met Office posted a few charts, one of which you can find on Twitter here: https://twitter.com/metoffice/status/1482605906659622914
Very interesting.

Clearly quite a bang.
The USGS has reported detecting the shockwave on its second trip round the Earth...

...and the data got a secondary application, too: https://www.mezzacotta.net/100proofs/archives/687 ;)
