Tsunami warning issued after 6.9-magnitude quake hits off northeastern Japan

A 6.9-magnitude earthquake hit off northeastern Japan on Tuesday, triggering a 1-meter tsunami warning for Iwate Prefecture, Japan's Meteorological Agency (JMA) said.

The quake, which occurred at 8:06 a.m. local time (2306 GMT Monday), was centered 210 km in the Pacific Ocean east of Miyagi Prefecture, with a depth of around 10 km. It registered 4 on the Japanese seismic intensity scale in parts of Aomori, Iwate, Miyagi and Akita prefectures.

The JMA has issued an advisory against a 1-meter tsunami for Iwate Prefecture in northeastern Japan.

According to Japanese public broadcaster NHK, Iwate's Miyako port and Kuji port have observed a tidal wave of about 10 cm respectively. The JMA is closely monitoring bigger tsunamis which may hit northeastern coastal areas later.

No death or injuries were reported immediately after the quake.
