An earthquake of 7.3 magnitude has hit 231 miles (371 kilometers) east of Japan’s Honshu Island with tremors felt in Tokyo. The quake prompted an evacuation at the devastated Fukushima Daiichi plant and sent tsunami fears across 5 prefectures.
The quake struck at a depth of 10 kilometers at 17:10 GMT, 320
kilometers southeast of Ishinomaki in Miyagi Prefecture,
according to the US Geological Survey. Strong tremors could be
felt on Japan’s main Honshu Island, as well as on the northern
island of Hokkaido.
A tsunami advisory was issued following the quake. The wave was due to hit at 17:42 GMT in the Fukushima region, the Japanese Weather Agency predicted. The agency issued a "yellow" warning meaning the tsunami was not expected to exceed a height of 1 meter.
Local media reports, that some 6,000 households were urged to
evacuate in Kamaishi, Iwate Pref. amid tsunami fears.
So far, a small tsunami of about 1 ft. (30 cm) was observed in Ishinomaki City, Miyagi Prefecture, meteorologists said. However, local NHK warns that tsunami could become stronger and higher.
