TOKYO: Japan issued an evacuation advisory for the coastal areas near the southern prefecture of Okinawa after a powerful earthquake triggered a tsunami warning.
A tsunami of up to 3m was expected to reach Japan’s southwestern coast around 10am (9am, Singapore time), according to the Japan Meteorological Agency. The warning came after an earthquake with a preliminary magnitude of 7.5 struck in the ocean near Taiwan.
The strong quake knocked out power in several parts of the city, according to a Reuters witness.
Earthquakes are common in Japan, one of the world’s most seismically active areas. Japan accounts for about one-fifth of the world’s earthquakes of magnitude 6 or greater.
On Mar 11, 2011, the northeast coast was struck by a magnitude 9 earthquake, the strongest quake in Japan on record, and a massive tsunami. Those events triggered the world’s worst nuclear crisis since Chernobyl a quarter of a century earlier.
