Three people were killed and many people were injured as a result of strong aftershocks in the north-eastern part of Japan. It was the strongest aftershock second power 9 points that triggered a devastating tsunami four weeks ago.
On a defective nuclear power plant Fukushima workers partially repaired equipment, providing protection during earthquakes. Therefore, as reported later, the operator station, there were no signs of deterioration.
The most recent earthquake occurred before midnight on Thursday, at a depth of 49 km, close to the epicenter of the earthquake that struck on March 11. At first it was reported that the magnitude aftershocks of 7.4 points, but later found out that the power was equal to 7.1 points, according to the U.S. Geological Survey (USGS).
The earthquake last month occurred at a depth of 32 km. More than 12,700 people are known to have died in the disaster and nearly 15,000 people remain missing. Hundreds of thousands were left homeless.
During the last earthquake 63-year-old woman died in hospital Yamagata Prefecture, where because of the strong aftershocks disconnected her respirator. In Miyagi Prefecture, two men aged 79 and 85 years old, also died in the hospital. Representatives of the Fire Department reported that the tremors caused heart attacks people.
Japan’s nuclear safety agency will send information about what equipment located along the northeastern coast were under control, although several sets of machines auxiliary diesel generators out of service after external power was lost.
Since the March 11 earthquake activities have been suspended at all nuclear power plants from Aomori to Ibaraki Prefecture, but the electricity is still in critical condition, so while it is impossible to maintain the function of cooling systems. Work on the damaged Fukushima Daiichi nuclear power plant are safe, according to the equipment operator "Tepco", (Tokyo Electric Power Company), provide information to the news conference in Tokyo. Company representatives noted that no new failures were found in the measurement of radiation levels or equipment.
Workers try to keep the damaged reactors cool to prevent further release of radioactive material. Work on the light emission of water at sea level radioactive waste from storage tanks will continue on Friday as officials said "Tepco".
The work aims to create a space for highly radioactive water that leaked into the foundation of the building with the turbines, located near the reactor No2 and the adjacent tunnel. The company also said it will continue work on the injection of nitrogen into the reactor vessel limiter No1, to prevent a possible hydrogen explosion.
