Along southern Alaska, the shockwaves were audible a few hours ago. I slept through it, but my feed has people complaining of having been woken up. Our local subreddits have posts from people being confused about potential thunder or military exercises. It is incredible to think of the energy involved in these events.

Do you know what time? I'd love to see if any of my cameras picked it up but hard to scrub audio in large quantities.

Around 4-5 AM AKST going off what I see others have been saying, sorry I don't know precise timestamps. One of the posts in /r/alaska was at 4:50 AM. One in /r/anchorage was at 4:39 AM.

Edit: Alaska Volcano Observatory just posted this graph of the pressure wave here

Put the audio in a tool that visualises it (e.g. Audacity), should make the segments easier to pick out than scrubbing.
