NNA – Japanese authorities issued a warning for a tsunami of up to 1 meter (3 feet) after a strong earthquake struck Monday in the seas south of Okinawa and east of Taiwan. The warning was cancelled just over an hour later.
The Japan Meteorological Agency said the epicenter of the magnitude-6.8 quake was at a shallow point near Yonaguni.
The tsunami warning remained in force for over an hour. No tsunami was recorded, and television footage of a nearby island showed calm seas.
The public broadcaster NHK said there were no initial reports of damage.
Witnesses said buildings swayed in Taipei but there was no visible damage in the Taiwanese capital.
