If you in a high rise hotel, the ground wasn't moving, you were! Buildings are designed to move back and forth in the wind. I felt the same thing years ago in a NYC hotel. Once you live through a quake you won't forget it, the last one I felt was last year was a 4.5 that was directly beneath my place in the East Bay (over the hills from Oakland). I was asleep and it took a few seconds to realize what was going on. We have had 3 earthquakes today north of us, I did not feel any of them. Usually in the range of 1.5 to 2.5. We had 360 earthquakes in the last 365 days! Welcome to California
Yeah, I knew that, but the 3AM mind farts played games during the night. Free associating what would/could happen if 'The Big One' hit. I was in the CN Tower during a 'windy day'. Not enough to close it down, but you could feel it swaying a little.
I also saw a building counter weight on a tour of a building. They exposed the thing, and it had marks inn the side of it where it apparently made contact with the structural members surrounding it. I was fascinated with how it worked, and wondered the process of getting it hung there during construction. Wow...
I remember an older gentleman commenting on fears. He said he's not afraid of falling, he's afraid of gravity. 'Look what it's done to my body!', pointing at the sagging skin, and his face. 'Gravity sucks!' he said to laughs. He was a delight...
TANGENT: Army brat, dad was stationed in Washington state. One morning, we had an earthquake. It was rather strong, and the mom freaked out. We lost a bunch of antiques and a few paintings off the wall. For a kid who hasn't felt the Earth move, yet, it freaked me right out... I was amazed at how some friends in California are so meh about earthquakes. I called them after a 'large' earthquake, and they were 'Hey, what's up?' So you had an earthquake? 'Yeah, didn't even knock anything off the shelves. I didn't even actually feel it. The wife did.' Hmm. I guess you can get used to anything.
