An earthquake with a magnitude of at least 6.1 has struck Taiwan.
The AFP news agency reported just after 02:00am local time on Wednesday that buildings in the East Asian state had shaken.
There were no immediate reports of casualties or damage.
The US Geological Survey registered the quake with a magnitude of 6.3, Reuters news agency reported.
The epicentre of the quake was near central Taiwan at a depth of about 15km, said Taiwan's Central Weather Bureau, which uses the Richter scale.
Earthquakes occur frequently in Taiwan, which lies on a seismically active stretch of the Pacific basin.
In September 1999, a 7.6 quake killed more than 2,400 people and destroyed or damaged 50,000 buildings.
