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.

--------------

9,700 KM distance Tonga - Whitehorse, YT

1,225 Km/hr speed of sound @ 20C

~7.9 Hrs to get here

3:10 PM AEDT Saturday 1st Explosion - 9:10 PM MST Friday + 8 Hrs = 5:10 MST Saturday

5:26 PM AEDT Saturday 2nd Explosion - 11:26 PM MST Friday + 8 Hrs = 7:26 AM MST Saturday

Accounting for inaccuracy, temperature changes along the way, wave diffraction, etc., I'd say you heard it.
