TAIPEI, Aug 27 (Reuters) - A magnitude 6 earthquake

struck in the sea off the northeast coast of Taiwan on

Wednesday, the island's weather administration said, with no

reports of damage.

The quake briefly shook buildings in the capital, Taipei.

The quake, some 20 km (12.4 miles) offshore from Yilan county,

had a depth of 112 km (70 miles), the weather administration

said.

Taiwan's fire department said it had received no reports of

damage.

TSMC, the world's largest contract chipmaker whose

factories are all on Taiwan's west coast, said the quake did not

reach the threshold for evacuations at its sites.

Taiwan lies near the junction of two tectonic plates and is

prone to earthquakes.

More than 100 people were killed in a quake in southern

Taiwan in 2016, while a 7.3 magnitude quake killed more than

2,000 people in 1999.
