TAIPEI (Reuters) - An earthquake with a magnitude of at least 6.1 shook Taiwan on Wednesday, official agencies said, but there were no immediate reports of casualties or damage.
The U.S. Geological Survey registered the quake with a magnitude of 6.3. The epicenter of the quake was near central Taiwan at a depth of about 15 km (9 miles), 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.
