Blast vs. Thunder
And I thought this was thunder! :confused:
No wonder a journalist friend of mine called to ask whether I was OK. When people were running out of buildings and what-nots, I was at home, sitting comfortably in front of my computer!
Updated: So apparently, the mysterious blast turned out to be sonic boom!

Oh, my. A full 10,000 meters above sea level and the boom was still strong enough to shake buildings? That can’t be good for the health!
