Sirens were wailing as city authorities responded to the quake, the news website said.
The quake struck about 4am local time, or 8pm Friday Irish time.
It was located some 22 miles south-east of Yujing, and struck about six miles underground, according to the US Geological Survey.
It was felt as a lengthy, rolling shake in the capital, Taipei, on the other side of the island. But Taipei was quiet, with no sense of emergency or obvious damage just before dawn.
