Tokyo: School children were evacuated to higher ground on some islands and buildings swayed in Taipei after a strong earthquake struck Monday in seas east of Taiwan and south of Okinawa.
Japan's Meteorological Agency issued an advisory for a tsunami of up to 1 meter (3 feet), but it was cancelled just over an hour later. The public broadcaster NHK said there were no initial reports of damage.
The epicenter of the magnitude 6.8 quake was at a shallow point near the Yonaguni islands, the agency said. It said no tsunami was detected.
Television footage of the area showed calm seas, but as a precaution school children in some low-lying areas of islands in the area were evacuated to safer locations.
In Taiwan's capital, Taipei, CCTV footage from a television broadcaster, TBS, showed signs and lights swinging from the ceiling of a newsroom, and some residents rushing into the streets after the quake struck.
