Are you misremembering the 6.4 from 2018 in Hualien?
There were no 7+ magnitude quakes in recent years. [1]
The closest is 2016 at 7.1 which took out some undersea internet cables the caused a reduction in spam worldwide of 50%. [2]
No there was definitely a 7 a few years back, I didn't say it was in Hualien. Do I really need to check this, for your convincing, can't you just believe me?
alright I checked: this is weird, but can't remember this one being a 6. Anyway, it was 7 on the Taiwan intensity scale. Maybe that's where I got it from?
