Earthquake in Japan: concern about nuclear plants

Japan was struck by the most violent earthquake in its history, Friday, March 11. The earthquake, of magnitude 8.9, occurred off the coast of northeastern Japan. Followed by many powerful aftershocks, it caused an impressive tsunami. Waves of up to ten meters high swept Sendai, the city closest to the epicenter of the earthquake.

The balance sheet, still tentative, reported at least a thousand dead and scores missing. In the evening, the city of Kesennuma (74 000 inhabitants) near Sendai, was the victim of major fires, and one third of its area was submerged by the tsunami. Moreover, according to Japanese news agency Kyodo, in the province of Fukushima, the level of radioactivity is a thousand times higher than normal at the entrance to the central atom of Daiichi and, according to Kyodo, there are leaks radioactive, that the authorities deny.

The Prime Minister, Naoto Kan, has asked people living within 10 km of the nuclear plant to evacuate. Concerns about a nuclear radioactivity level 1000 times higher than normal was found Saturday morning in the control room of reactor No. 1 of the Fukushima nuclear power plant No. 1, according to Kyodo News, quoting a commission security.

Japanese Prime Minister, Naoto Kan, has asked residents to evacuate within a 10 kilometer radius around the site, due to a risk of radioactive leakage, according to Jiji Press, citing the Ministry of industry. Saturday morning, the media reported that a second nuclear power plant in Fukushima Prefecture was having problems cooling.

The Japanese government had reported earlier a limited risk of radioactive leakage due to failure of the cooling system of a reactor of the plant. During the day, the governor of Fukushima Prefecture had he ordered the evacuation of six thousand people living within a radius of three kilometers around the nuclear plant because the authorities were preparing to release of radioactive steam to let off pressure which amounted to a reactor of the plant.

Shortly before, a spokesman for the company that operates the site, Tokyo Electric Power, had recognized that the pressure mounted inside one of the reactors. "The pressure has increased in the box and we try to manage the situation," Bush said. The U.S. Air Force has also recovered from the coolant at a Japanese nuclear power plant, announced Secretary of State Hillary Clinton, without specifying how it was installed.

A total of eleven reactors were automatically stopped when the earthquake, according to the Ministry of Industry. Apocalyptic scenes in the archipelago Four trains, with an unknown number of passengers were reported missing Friday in the evening. In Miyagi Prefecture, a boat was swept away, and we knew the fate of a hundred people on board.

In Iwate Prefecture, forty-eight, twenty-three college students were missing in the port of Ofunato. In Tokyo, about 380 kilometers from the epicenter, the skyscrapers built on special earthquake resistant structures, have pitched for several minutes after the earthquake. A roof collapsed on a building in the center of the capital, where six hundred students attending a graduation ceremony, leaving many injured, according to firefighters.

A dozen fires were reported in Tokyo. In the region, an oil refinery was on fire and flames Iichihara amounted to several tens of meters high. More than four million homes were without power. Transport severely disrupted International Airport in Narita, east of Tokyo, has suspended traffic for several hours, but announced this evening that the operations resumed gradually.

The rail and road transport were also disrupted in large parts of the archipelago, particularly in Tokyo and its surroundings. Shinkansen express trains were stopped across the Northeast and the motorways of the Tokyo area closed a few minutes after the earthquake. The correspondent of the "World" in Tokyo, Philippe Mesmer says that these blockades have forced many employees to return home on foot.

Some chose to spend the night in their company's premises for safety. Listen! Alerts in the Pacific, no significant damage to the earthquake, most of the states bordering the Pacific have issued advisories warning of the tsunami. But no significant damage had been reported outside the Japanese archipelago.

Coastal areas were evacuated preventively the Philippines, the Marianas, French Polynesia, Guam, Hawaii, Ecuador, Canada and other countries. A "warning" alert level agent, has been issued for a portion of California, part of Alaska and Washington State, where he was asked residents to leave beaches, harbors and marinas.

A similar measure was taken in Canada. Waves of less than one meter have been reported. In Central America, Costa Rica, Honduras, Guatemala, Nicaragua and Panama have also issued a tsunami warning for their peaceful facade. El Salvador has only issued a "warning" and, further south, Ecuador, President Rafael Correa declared a state of emergency for a period up to sixty days and ordered "the evacuation of all residents Rim countries and the province of Galapagos "(a thousand miles west of Ecuador's coast), about three hundred thousand people.

Japan, located at the junction of four tectonic plates, experiences each year about 20% of the strongest earthquakes reported. In 1923, the city of Tokyo had been devastated by a major earthquake, which had one hundred and forty thousand dead. More recently, in 1995, the Kobe earthquake (West) had more than six thousand four hundred dead.
