A magnitude 6.2 earthquake was reported Saturday evening at 10:11 p.m. Pacific time 13 miles from Yilan, Taiwan, according to the U.S. Geological Survey.
According to the USGS, the epicenter was further than 100 miles from a city.
In the past 10 days, there have been two earthquakes of magnitude 3.0 or greater centered nearby.
It hit northeastern Yilan county at 1:11 pm (0511 GMT) at a depth of 67 kilometres (42 miles).
The Taipei metro was briefly closed for checks, but re-opened shortly afterwards. The state-run power operator said the grid was operating as normal, while the railway administration said it was carrying out track inspections.
Taiwan Semiconductor Manufacturing Co Ltd (TSMC) (2330.TW), the world’s largest contract chipmaker, said it had evacuated some workers.
“Personnel at certain TSMC fabs in north Taiwan evacuated during the earthquake as per company procedure, and all safety systems functioned normally,” it said in a brief statement.
Taiwan lies near the junction of two tectonic plates and is prone to earthquakes.
More than 100 people were killed in a quake in southern Taiwan in 2016, while a 7.3 magnitude quake killed more than 2,000 people in 1999.
