I don't know if Taiwan is prone to earthquakes but parts of the island are subject to tsunamis and the entire island is prone to regular,huge,typhoons.
I wouldn't assume that. Not that Wikipedia is the final word, but according to this disambiguation page:https://en.wikipedia.org/wiki/Fukushima_Nuclear_Power_Plant , there are 2 Fukushima nuclear plants, one put in service in 1971, and one put in service in 1982, which was less affected.
There were also safety violations at one or both of these plants which were unreported for a long time.
And then there is this: Tremors exceeded design limits for 3 reactors.
