Taipei: A 5.5-magnitude undersea earthquake struck Taiwan Wednesday and shook buildings in the capital, but there were no immediate reports of casualties or damage.
The quake struck at 3:54 pm (0754 GMT) with its epicentre 87.5 kilometres (54 miles) southeast of the northeastern city of Yilan at a depth of 83.1 kilometres, the central weather bureau said.
Residents on many parts of the island felt tremors, it said.
The island lies near the junction of two tectonic plates and is regularly hit by earthquakes.
A strong 6.3-magnitude quake which hit central Taiwan in June last year killed four people and caused widespread landslides.
A 7.6-magnitude quake struck the island in September 1999 and killed around 2,400 people.
