Almost a million households in Japan are still without electricity after an earthquake of 7.1

Nearly one million Japanese households are now without electricity and nuclear power Onagawa has been a leak of radioactive water after the 7.1-magnitude earthquake that killed three people last night and hit the areas devastated by the tsunami of 11 March. Half an hour before midnight yesterday shook northeastern Japan with the replica that has felt stronger since 9 earthquake, which struck the coast of Miyagi, Iwate and Fukushima four weeks ago.

Onagawa nuclear plant in Miyagi province (northeastern Japan), suffers from water leaks after a strong earthquake yesterday but was not detected by the time an increase of radioactivity, NHK reported. Two other nuclear power plants in eastern Japan have had to rely on emergency generators after losing power outside the 7.1-magnitude earthquake last night on the coast of Miyagi, causing at least two dead and 134 wounded.

Onagawa plant, very near the epicenter of the quake, has lost two of its three external electrical lines, although at the moment is cooling pools for spent fuel supply line to the left, according to the Nuclear Security Agency of Japan. Onagawa, who was standing from the earthquake and tsunami of March 11, suffered the temporary suspension of refrigeration systems after yesterday's earthquake, but the technicians finally recovered.

The central Higashidori in Aomori, remained after the earthquake without external power and is now working with emergency diesel generators, although at the time of the quake was under review and has not reported problems. Also in Aomori, the central processing Rokkasho nuclear waste was left without electricity and operating with emergency generators.

In the central Fukushima, affected by severe infiltration by the earthquake and tsunami nearly a month ago, has not detected an increase in the radiation out of the ordinary, according to the nuclear agency. Daiini Fukushima plants and Tokai (Ibaraki) have also been problems and unusual records.

New quake An earthquake of magnitude 7.1 on the Richter scale shook northeastern coast of the archipelago to 23.32 (seven hours behind mainland Spain), leaving at least two victims. A total of 12,608 people were killed and 15,073 remain missing in the earthquake and tsunami last month. The Japanese Meteorological Agency also issued a tsunami warning for up to two meters, then canceled.

The quake forced the evacuation of a shelter to earthquake-proof emergency teams from the massive earthquake and tsunami last month, fighting in the Fukushima nuclear power reactors to prevent melt and cause a massive leak of radiation. Tokyo Electric Power (TEPCO), the owner of the plant, said plant apparently had not suffered further damage from the quake.

It was the most potent of the more than 400 aftershocks have occurred since the devastating earthquake of March 11, except for several that occurred that day. The earthquake occurred at about the same area and at the same depth as last month, on the northeast coast of the island of Honshu, the largest in Japan, 65 kilometers from Sendai (the capital of Miyagi Prefecture) and 330 kilometers from Tokyo, according to the U.S.

Geological Survey (SGEE). The epicenter was 50 kilometers under the sea. Initially announced the magnitude was 7.4, but then reduced it to 7.1 SGEE. The quake was felt strongly in Tokyo, where earthquakes occur almost daily. Some are barely imperceptible movements which produce a kind of dizzy too fast, others slightly shaken buildings.

Yesterday was particularly long and intense. The hotel where I was this correspondent, on the tenth floor, creaked and swayed for a minute that seemed an eternity. In the city of Ishinoseki (Iwate prefecture in the north), the buildings were shaken violently, but were not seriously damaged, "the furniture overturned and cut the power supply.

In Sendai (Fukushima Prefecture), the light was in parts and there were leaks and gas. The Meteorological Agency issued a tsunami alert. "Please, contact to higher ground, and not trying to return to the waterfront," repeated the NHK television network, an apparent reference to the fishermen worried about their boats.

About an hour and a half later canceled the alert, but warned people not to approach the coast. The quake broke several power lines in the central atomic Onagawa, north of Sendai, which is closed since the tsunami. A line is still running and no radiation leaks were detected. Both the central, and Higashidori Rokkasho in Aomori Prefecture, briefly lost external power source cooling systems of reactors, but all retain at least one emergency system operating.

After the earthquake, TEPCO said it continued injecting nitrogen into the reactor number 1. The company warned last Wednesday that hydrogen is accumulated in the reactors, which could cause an explosion similar to what occurred at the plant in the early days of the disaster, and yesterday began injecting nitrogen into the reactor containment vessel in order to displace the oxygen.

Plans to do the same in reactors 2 and 3, as a precaution. South Korea fear Fear of the invisible has also reached South Korea. Dozens of schools canceled Monday classes in China for fear that the rain that fell throughout the day was full of radioactivity from Fukushima. More than 130 kindergartens and elementary schools in Gyeonggi province which surrounds Seoul, cut hours or lessons canceled by order of the regional education department.

The move was said, because "the increasing anxiety among students and parents through the conflicting information regarding the safety from exposure to radiation." The Department of Education in Seoul, however, refused to cancel classes, despite the requests of many parents, and appealed for calm.

The Government said the amount of radiation detected in the rain was very small and posed no health risk. But not only South Korea is worried about Japan's nuclear crisis. The Chinese Health Ministry said yesterday that it had found traces of radioactivity in the spinach in three provinces, including Beijing.

The Government also said it has detected radiation in air in 22 provinces, although the levels are not harmful to health. India banned earlier this week the Japanese food imports for three months. And Russia has also expressed concerns. The police entered the security perimeter Fukushima Around 300 police officers (240 in Tokyo and Fukushima 50) are inspecting the 20 km around the nuclear plant in Fukushima Japan established the Government as security perimeter when there was a plant accident.

The officers started the operation yesterday, wearing chemical protective clothing. For now, have concentrated their efforts on removing the debris with heavy equipment to comb the area for the first time since the earthquake took place in March. They have not unearthed any body on the first day, only recovered headstones photos and to return them to the families of the victims, as reported by the Kyodo News agency.

The rescue operation had been delayed several times because local police refused to enter the area to collect the bodies had been decontaminated without first security perimeter. The bodies are almost a month exposed to high radiation levels and their identification may be difficult. It has even been speculated that the cremation could cause radioactive contamination in the air.

The Japanese authorities are confident that these tasks serve to retrieve the remains of at least a thousand people, which so far are still on the missing list. Meanwhile, the Japanese authorities are considering extending the mandatory evacuation zone around the plant in Fukushima. The Government has recommended to the residents now in the range between 20 and 30 miles do not go on the street or they leave voluntarily.

But last week the International Atomic Energy Agency and the environmental organization Greenpeace called on Tokyo to expand the exclusion zone had been detected because high levels of radioactivity in locations up to 40 kilometers.
