Taiwanese authorities say a 6.3-magnitude earthquake has struck off the east coast of the island, rattling buildings in Taipei, but causing no casualties or damage.

The Central Weather Bureau says the quake struck at 2:05 a.m. Tuesday. It was centered about 36 miles off the eastern city of Hualien, some 85 miles southeast of the capital.

Earthquakes frequently rattle Taiwan, but most are minor and cause little or no damage.

However, a 7.6-magnitude earthquake in central Taiwan in 1999 killed more than 2,300 people. And in 2006 a 6.7-magnitude tremor south of Kaohsiung severed undersea cables and disrupted telephone and Internet service to millions throughout Asia.
