Is there any website tracking how long the sound would take to reach various locations? I’m guessing I might be able to hear a gentle rumble in SF
Edit: some Googling tells me it's about 5300 miles from SF to this volcano. At 767mph, that's 6 hours and 54 minutes. The volcano erupted at 8:26pm Pacific, meaning at around 3:20am Pacific time the sound should reach SF.
I live in the Yukon Territory, Canada... Not 100% sure this explosion is what woke me this morning but:
I woke up at 7:15 AM MST to what I though was a freight truck loading boxes at the business next door. Rumbling, thudding noises. Very faint. Promptly ignored it and tried to go back to sleep, a few moments later my sister 100 KM outside of my location on a off-grind property texted me asking if I could hear thunder/fireworks like noises outside. Noise probably lasted 10-15 minutes.
I did some napkin math for speed of sound and it gets close.
It was heard in NZ, some as south as Christchurch claiming to have heard it. In in Christchurch and didn't hear it but did see changes in air pressure was the sound waves went through.
