TAIPEI, Taiwan >> A powerful earthquake has struck off northeastern Taiwan, but there were no immediate reports of casualties or damage and no tsunami warning issued.

Taiwan’s Central Weather Bureau says the quake registered at magnitude 6.5. It says the tremor was felt throughout the island.

The earthquake struck Sunday morning at sea, about 42 miles east of the Taiwanese county of Ilan. Ilan is about 90 miles southeast of the capital, Taipei.

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

However, a magnitude-7.6 earthquake in central Taiwan in 1999 killed more than 2,300 people.
