I’m sure some people just slept through it. They were shaken but not stirred.
Funny.
I once slept through a 5.5 in Manila in a hotel located on unstable ground next to the harbor. One of the guys in our party the next morning said he’s been thrown from his bed and could not believe I hadn’t noticed it. The Bologna, Italy quake a few years ago woke me with gentle shaking as I was a hundred or so miles away in Verona. Every earthquake I’ve ever experienced has felt different, some quick and violent and others like the motion of a ship at sea. All of them, if you’re awake, can scare the living $*** out of you.
