A sesma of 7.1 shook the northeastern coast of Japan, but not the central Fukushima daa

An earthquake measuring 7.1 on the Richter scale has hit today the northeastern coast of Japan, an area devastated by the earthquake of 11 March. Initially caused a tsunami alert that has since been canceled. The quake occurred at 23.34 local time (14.34 GMT) and the hypocenter is located 40 miles deep off the coast of Miyagi province, hardest hit by the earthquake of 9 degrees for about a month according to the United States Geological Survey (USGS).

The earthquake did not affect nuclear plant in Fukushima, stricken after the earthquake and tsunami of March 11, as announced at a press conference a spokesman for TEPCO, the company that operates the plant. However, the company has evacuated the workers as a precaution. The quake also damaged the plant in Fukushima-2 or that of Onagawa, according to Kyodo.

The central government, with Prime Minister, Naoto Kan, head, has convened an urgent meeting to address the response to the earthquake. Khan has been ordered to examine the affected area and assist those affected. Meanwhile, we take the work to stabilize the stricken plant. Continue normal operations on to cool the reactors 1, 2 and 3, NHK television reported.

According to TEPCO, there has been no damage to any of the six reactors at the plant. Radiation levels remain within normal limits, according to the spokesman added. After the earthquake there have been power outages in Miaygi and Yamagata prefectures, according to Japan's Kyodo news agency reported.

The disruption of supply has also affected all areas of the prefectures of Aomori, Iwate, Akita. In the Onagawa nuclear plant have not been detected abnormal levels of radioactivity. The USGS has indicated that the quake originated 66 kilometers from the city of Sendai and Fukushima 118 kilometers from one of the areas most affected by the earthquake and tsunami nearly a month ago.

The U.S. Geological Survey initially set the magnitude at 7.4 but later was reduced to 7.1. Tokyo figure, according to data from USGS, to 333 kilometers, but also cited by several witnesses have confirmed that they have felt the effects in the capital. The Japan Meteorological Agency initially triggered the alert of tsunami in the northeast of the country amid fears that are produced waves of about two meters, but then aborted.

The alert included a coastline of 420 kilometers, from Aomori Prefecture in northern Ibaraki Prefecture in central China, north of Tokyo. It has also recommended the evacuation into people who are on the coast. The authorities have given orders to close all highways in the prefecture of Miyagi, near the epicenter, according to Kyodo, which also reports of power outages in areas of Fukushima and Yamagata.

"Based on all available data, no destructive tsunami is expected to reach across the Pacific," said on its website the Tsunami Warning Center Pacific. But he warned that: "Earthquakes of this size sometimes generate local tsunamis that can be destructive along coasts located within a radius of 100 kilometers from the epicenter of the earthquake." Since the earthquake on March 11 there have been hundreds of sequels but few have been of a magnitude greater than 7.

The combination of earthquake and tsunami left about 28,000 dead and missing, and hundreds of thousands of displaced people after the catastrophe that has devastated the Miyagi Prefecture. Fukushima evacuation perimeter While the nuclear crisis drags on, the Japanese government is studying the possibility of expanding the evacuation area of 20 to 30 km around the plant, because of the danger posed by exposure to radiation for long periods of time .

Until now there was only the recommendation to stay at 30 kilometers, while the evacuation zone is maintained from the first day of the accident, 20 miles. This was stated Yukio Edan, government spokesman has stated that these guidelines "are set assuming an accident that releases a high level of radiation in a short space of time", according to Efe.

From Vienna, the International Energy Agency (IAEA), has assured that there are some signs of progress in stabilizing the plant, although the overall situation is serious. "Our estimate of the situation remains very serious Fukushima although there are some signs of recovery in some functions such as power and instrumentation," said Denis Flory, senior member of the body, in a press conference.
