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.
Edit:
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.
