A 6.2-magnitude earthquake jolted off Taitung of Taiwan island at 4:06 a.m. Saturday (Beijing Time), according to the China Earthquake Networks Center.

The epicenter was monitored at 22.6 degrees north latitude and 121.5 degrees east longitude, and the focus of the quake was 7 kilometers deep, the center said in a statement. No casualties or damage have been reported.

Taiwan's earthquake monitoring department said that almost the entire island was affected by the quake to varied intensities. An unnamed tourist near the Sun Moon Lake in central Taiwan told Xinhua that the bed was shaking for about half a minute. The quake was not clearly felt in Taipei.

The quake is the first one above the 6.0-magnitude reported in Taiwan this year, according to the department.
