5.5-magnitude quake hits off Taiwan
The tremor, which was also felt in the capital Taipei in the north, struck at 11:39 am (0339 GMT), 46.9 kilometres (29 miles) southeast of Hualien on the east coast, at a depth of 16.9 kilometres under the sea, the centre said today.
Taiwan lies near the junction of two tectonic plates and is regularly hit by earthquakes.
In September 1999, a 7.6-magnitude tremor killed around 2,400 people in the deadliest natural disaster in the island's recent history. (AFP)
