While I haven’t been inside Taipei 101, I have viewed it from the recommended vantage point of Elephant Mountain. It is an impressive building and standing at 508 metres tall and 200 metres from a major fault line, earthquakes and high winds are a serious threat. TIL to combat this it is home to the heaviest and largest tuned mass damper in the world, which sits between the 88th and 92nd floor and is capable of moving a metre and a half in any direction to reduce the sway of the building by 30 to 40 percent. I will have to visit next time I’m in Taipei.
