TAIPEI--The tsunami threat from a strong earthquake that struck Taiwan has largely passed.

The Japan Meteorological Agency downgraded its forecast from 3 meters (9.8 feet) to 1 meter (3.3 feet). One island had a wave of about 30 centimeters (a foot), while smaller waves were detected in other islands.

Japan’s Chief Cabinet Secretary Yoshimasa Hayashi said there has been no report of injury or damage in Japan. He urged the residents in the Okinawa region to stay on safe ground until all tsunami advisories were lifted.

China issued no warnings for the Chinese mainland, and there was no threat for Hawaii and Guam.

More than two hours after the 7.4 magnitude quake struck Taiwan, the Pacific Tsunami Warning Center said the threat of a tsunami has largely passed.
