A 7.3 magnitude earthquake hit off the coast of Japan, close to where previous mega-quake struck on March 11 of this year.
A major earthquake struck off northeastern Japan Sunday, prompting tsunami advisories for several coastal regions, the Japan Meteorological Agency (JMA) said. There were no immediate reports of injuries or damage, according to the Japanese news agency Kyodo. The U.S. Geological Survey said the earthquake struck at 10:57 a.m. at the epicenter, about 130 miles east of Sendai. The earthquake was more than 20 miles deep and had a magnitude of 7.3, the USGS said. The JMA measured the magnitude of the quake at 7.1. Tsunami advisories were issued for the coastal regions of Iwate, Miyagi and Fukushima, the JMA said. The areas were among the hardest hit by this year's devastating earthquake and tsunami. Officials in Ofunato, a city in Iwate, advised residents to evacuate. The JMA forecast the height of the tsunami could reach half a meter (about 20 inches). No immediate abnormalities were reported at nearby nuclear facilities, according to Kyodo. Three reactors at the Fukushima Daiichi nuclear power plant suffered meltdowns after the March 11 earthquake and tsunami that devastated northern Japan. The tsunami swamped the plant and knocked out cooling systems that kept the three operating reactors from overheating, leading to the worst nuclear accident since Chernobyl. Tremors from Sunday's quake were felt as far away as Tokyo. "It's just a continuing of the aftershocks of that devastating 9.0," said Dale Grant, a geophysicist with the USGS, referring to the March quake. "These kinds of aftershocks are likely to occur for some time." - CNN.
Small tsunami waves reached the Pacific coast of northern Japan Sunday after a major quake hit the region heavily damaged by the March earthquake and tsunami, the Japan Meteorological Agency said. The port towns of Soma and Ofunato saw 10-centimetre (four-inch) tsunami waves triggered by the 7.3-magnitude earthquake that struck off the main island of Honshu at 9:57 am (0057 GMT), the agency said. No damage has been reported from the tsunami and quake, which was strong enough to sway skyscrapers in Tokyo, some 400 kilometres from the epicentre. The Japanese agency and the US Geological Survey originally estimated the quake's magnitude at 7.1, hitting the same general area as the 9.0-magnitude quake of March 11 which triggered a massive tsunami. While Japan upgraded the quake to 7.3, the US agency revised it down to 7.0, centred 212 kilometres (131 miles) east of Sendai city, Miyagi prefecture, at a depth of 34.9 kilometres. The Japanese agency lifted the tsunami advisory at 11:45 am. "Changes in sea level may occur for the next few hours. Please use caution when conducting activities near the ocean, such as swimming and surf fishing," a Japanese weather agency official told a news briefing. Television footage of Ofunato and Soma did not show any visible sign of the tsunami, with the water surface seemingly calm and flat. Tokyo Electric Power Co (TEPCO) said the latest quake did not cause fresh problems at the crippled Fukushima Daiichi (number one) nuclear plant and the nearby Fukushima Daini (number two) plant. "We have received reports that there has been no significant impact at the Fukushima Daiichi and the Fukushima Daini nuclear plants," a TEPCO spokesman told a news conference. Cooling of crippled reactors at Fukushima Daiichi continued, although the company told work crews near the water to seek higher ground during the tsunami advisory. The Japanese weather agency originally expected a small tsunami of up to 50 centimetres (20 inches) along the affected region. Communities along the Pacific coast issued warnings and advisories for local residents to seek higher ground or to leave areas near the water. "For a second, I thought maybe another big one will come," a middle-aged man in coastal Kesennuma, Miyagi, told national broadcaster NHK. The devastating March 11 and tsunami left about 22,000 people dead or missing and triggered an atomic crisis at the Fukushima Daiichi nuclear plant. - AFP.
