An earthquake with a magnitude of 6.5 has struck Taiwan, the country’s weather bureau has said.
It had a depth of 41.5 miles (66.8km) and could be felt across northern and eastern parts of the island, it added.
The epicentre was in Yilan county, and buildings shook in the capital, Taipei.
There are no reports of any damage, however.
The power grid is running normally, the state-run operator said, and while the Taipei metro was briefly closed for checks, it re-opened shortly afterwards.
Some workers were evacuated at Taiwan Semiconductor Manufacturing Co Ltd – the world’s largest contract chipmaker.
That was carried out “as per company procedure” and “all safety systems functioned normally”, the company said.
Taiwan is situated close to the junction of two tectonic plates and is prone to earthquakes.
