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.
