Another concern is building stability, whether or not the actual construction process followed code, whether or not structural maintenance is adequate, & the age of some high rises. Florida recently had a condo collapse. There are many old tall buildings built on shifting water permeable ground in the US.
China has issues with tall buildings as well, particularly in it's river flood plains. It is quite surreal to see an entire high-rise being carried down a river. Look it up.
Edit:
I was unable to find the video with today's search...so here is the video. Apparently there was censorship with the Chinese government over the video.
