Probably not. It’s generally only really tall buildings. This one has 79 stories, 20 years old.

we had a clown in the office who hung a full beer can on a long string from the top of a doorframe. on really good days you could hear the THUNK every few minutes as the can hit one side of the door or the other. fun times!

Is there a theater in upper floors of the building? A large audience could create a time warp event.

A few videos have popped up since this item was posted that show the shaking a bit better.

Whenever I was in the Windy City, I’d visit the observation deck of the Willis Tower back when it was still the Sears Tower. It did the same thing. I enjoyed it knowing it was safe, but I can see how that’d be nope city for anyone with even mild vertigo.

That satire flash was important, because I could swear that they were talking about the Grenfell tower.

i’m having a hard time even guessing which building is supposed to be the one wobbling – is it the shorter one, or the taller one?

Thank you for that kind response. I transposed the numbers in my head. :-/

Not sure about active, but tuned passive mass dampers are used in smaller structures for sure. According to Wikipedia they are in pedestrian bridges in Vegas as well as a variety of vehicles.
My recollection is that the now old Oracle HQ in Redwood Shores, all less than 20 stories, had mass dampers.

Note to aspiring videographers: if the thing in question is a building shaking, get footage of the building shaking. Not seasick up-and-down wobbles alternating between the wrong building and the crowds below. Ugh.

It happens, no sweat.

Thanks for that. In the video posted by boing boing, I thought it was the white building that was supposed to be swaying, and I couldn’t see any movement.

OK - I have been in SEG many times … the building that all the people appear to be running away from is NOT SEG - SEG is the hexagonal thing shown at the end of the clip

I had an earthquake hit while in the WC in Wyoming. I was like why is there pee everywhere?! Washed up and walked into a kitchen in chaos… Deep fry oils sloshed hot on the floor, bottles and plates fallen and shattered. It was a mess.
In CA get instantly motion sick when there is anything above a 2.5 quake within 200 miles or so. Sometimes I know about it before my local Twitter fires up.
I found out this week about a 32 year long “slow earthquake” this week in science. Seems most earthquake models need revision to account for these previously unknown phenomenon.
For example Wikipedia defines it as “weeks or months”
Apparently some coral were observed carefully:

Well, as I bike riding Scot, I can see where some traditionally clad chaps would indeed have trouble with mounting or dismounting their pennyfarthing or velocipede.
