Tokyo stocks flat amid uncertainty over economic impact from quake Thursday 07th April, 03:20 PM JST TOKYO —
Tokyo stocks ended almost unchanged Thursday, with support from gains on Wall Street and a weaker yen being tempered by uncertainty over the economic impact of the March 11 quake-tsunami disaster. The 225-issue Nikkei Stock Average rose 6.56 points from Wednesday to 9,590.93. The broader Topix index of all First Section issues on the Tokyo Stock Exchange was up 1.49 points to 841.10.
After a two-day losing streak, both indexes advanced strongly at the outset of trading, following the rise in U.S. stocks overnight in New York, where the Dow Jones Industrial Average closed at its highest level since June 2008 on solid U.S. manufacturing data, brokers said.
A weaker yen against the U.S. dollar and the euro was also supportive as it lifted some export-oriented shares.
But the market’s rise soon lost steam amid a wait-and-see mood hanging over the market ahead of the release of earnings reports later this month that would reflect the impact of the March 11 disaster, they said. |

Japan says dumping radioactive water in ocean doesn't violate law Tuesday 05th April, 06:40 PM JST
FUKUSHIMA —
The Japanese government on Tuesday defended its dumping of massive low-level radioactive water from the crisis-hit Fukushima nuclear plant, saying the action does not violate international laws, and pledged to fully inform the international community of Tokyo’s steps to tackle the ongoing emergency.
Foreign Minister Takeaki Matsumoto said at a press conference that Tokyo had briefed diplomatic corps in Japan on the start of radioactive water disposal hours before the plant operator Tokyo Electric Power Co (TEPCO) began releasing the liquid into the Pacific Ocean on Monday evening.
The minister stressed that the discharge poses ‘‘no significant health threats’’ to human bodies, but said Tokyo will explain to other countries about the background of measures taken at the Fukushima plant, where the nation’s worst nuclear crisis is unfolding following the March 11 massive earthquake and tsunami.
He also said the dumping does not violate the 1986 Convention on Early Notification of a Nuclear Accident, which obligates nations to provide data such as the accident’s time, location and radiation releases to affected states when harmful trans-boundary radiation release is feared.
The treaty also encourages voluntary reporting of accidents that do not meet the criteria for mandatory notification. Matsumoto said Tokyo has notified the International Atomic Energy Agency of the radiation leak in accordance with the pact.
Chief Cabinet Secretary Yukio Edano separately said Japan contacted the IAEA rather than individual neighbors because the water has been released from the plant on the Pacific coast. The top government spokesman also said the discharge would ‘‘not cause immediate radioactive contamination in neighboring countries.’‘
Matsumoto also said Japan has been making its best efforts to minimize the sea contamination in line with the U.N. Convention on the Law of the Sea.
Meanwhile, a total of 60,000 tons of radioactive water is believed to be flooding the basement of reactor buildings and underground trenches connected to them at the crisis-hit Fukushima nuclear plant, the industry minister said Tuesday, adding that its operator will later remove the liquid obstructing recovery work.
TEPCO began dumping low-level radioactive water into the Pacific Ocean on Monday as an emergency step to secure room for the storage of more highly contaminated water. TEPCO aims to dispose of a total of 11,500 tons of low-level tainted water into the sea by this weekend from the plant on the coast.
Economy, Trade and Industry Minister Banri Kaieda maintained that contamination of the sea to be caused by the disposal will pose no major health risk, while apologizing for raising concerns among the public, especially fishermen.
In another sign that contamination is affecting the marine environment, however, radioactive cesium exceeding the maximum allowable limit was detected in young launce taken Monday in the sea near the northern part of Ibaraki Prefecture, the prefecture’s fishery cooperative said. It is the first time that contamination levels in seafood have exceeded the limit.
The Nuclear and Industrial Safety Agency said the 60,000 tons of water—20,000 tons each from the Nos. 1-3 reactor buildings and trenches—will be stored in tanks at the units, a facility for nuclear waste disposal at the site, an artificial floating island called a ‘‘megafloat,’’ U.S. Navy barges and provisional tanks.
The complex for nuclear waste disposal can accommodate 30,000 tons of such water but it will take a while before it can store the liquid because TEPCO will try to ensure that radioactive water will not leak from the facility by using coating agents, the agency said.
The provisional tanks will be shipped to the Fukushima plant by the end of this month, it added.
Meanwhile, TEPCO began work Tuesday afternoon to stop the leakage into the sea of highly radioactive water believed to be originating from the No. 2 reactor’s core, where fuel rods have partially melted.
The water containing radioactive iodine-131 more than 10,000 times the legal concentration limit has been leaking from a cracked seaside pit connected to the No. 2 reactor turbine building.
In a new finding, TEPCO said a seawater sample taken Saturday near the No. 2 reactor’s water intake showed the iodine-131 concentration at 7.5 million times the maximum allowable level under law.
To halt the flow of radioactive water, the operator injected ‘‘water glass,’’ or sodium silicate, shortly after 3 p.m. into graveled areas beneath the pit’s bottom, where radioactive water is believed to be seeping through.
The utility has tried to block the radioactive water leakage with concrete and water-absorbing polymeric materials, but its efforts have so far been unsuccessful.
TEPCO has also poured in white bath agents to trace the route of the leakage but colored water did not emerge from the seaside pit, leaving the path of contamination unknown.
Removal of tainted water is necessary to reduce the risk of workers being exposed to radioactive substances and facilitate efforts to restore vital cooling functions to cool down the reactors and spent nuclear fuel pools at the site, which was ravaged by the devastating March 11 quake and tsunami.
The utility has been pouring massive amounts of water into the reactors and their spent nuclear fuel pools as a stopgap measure to cool them down, because serious damage to the fuel rods from overheating could lead to the release of enormous amounts of radioactive materials into the environment.
However, the measure is believed to be linked to the possible leak of highly contaminated water from the reactors |

Tepco succeeds in plugging leakReactor to be injected with nitrogen to avert hydrogen blast
By MASAMI ITO
Staff writer
Tokyo Electric Power Co. finally succeeded in stopping the main leak of highly radioactive water from the damaged Fukushima No. 1 nuclear plant into the ocean Wednesday morning and workers were preparing to inject nitrogen into at least one reactor in a bid to prevent another hydrogen explosion.

Tepco said it confirmed at 5:38 a.m. that a crack in the No. 2 reactor storage pit had been plugged after workers injected 1,500 liters of sodium silicate and another agent to solidify a layer of small stones under a cable trench.
"I have been told that it is being thoroughly looked into whether the leak has completely stopped and whether there are other (cracks)," Chief Cabinet Secretary Yukio Edano said. "We have not stopped worrying just because the leak supposedly stopped."
The highly radioactive water is believed to have come from the No. 2 reactor core, where fuel rods have partially melted, and ended up in the pit. The pit is connected to the No. 2 reactor turbine building and an underground trench connected to the building, both of which were found to be filled with high levels of contaminated water.
To make room to store the highly radioactive water that is hampering repair work at the plant, Tepco continued to discharge massive amounts of low-level contaminated water from inside a nuclear waste disposal facility at the site and from around the No. 5 and 6 reactor buildings.
As of 6:30 a.m., about 10,000 tons of low-level radioactive water had been discharged and about 600 tons were left, the Nuclear and Industrial Safety Agency said.
Edano meanwhile apologized to fishermen and said those whose catches have been affected by the release of low-level radioactive water should be compensated. He also apologized to neighboring countries, including South Korea, which have expressed deep concern at the lack of information from the Japanese government prior to its decision Monday to release low-level radioactive water from the nuclear plant into the sea.
"We must earnestly accept words that we should have explained the situation in detail and more thoroughly to related ministries and neighboring states before the release," Edano said. "It was to prevent further leaking of (highly radioactive) water into the sea, but we should have thoroughly explained the situation beforehand."
Meanwhile, excessive levels of radioactive cesium were detected in young sand lances in the sea off northern Ibaraki Prefecture.
Given the development, the National Federation of Fisheries Cooperative Associations issued a statement Wednesday slamming Tepco and the government.
"It is natural that the damage to and effects on the marine industry be included in the compensation" program along with the agricultural products, Edano said.
Tepco revealed Tuesday it hopes to provide provisional compensation to locals and farmers near the plant. Details have yet to be worked out but the utility said it has begun consulting with the government.
Tepco said Wednesday that workers were set to inject nitrogen into reactor No. 1 later in the day to prevent another hydrogen explosion like the one in the reactor on March 12. They are also considering injecting nitrogen into reactors 2 and 3. Information from Kyodo added |

LAGI GEMPA BUMI! TSUNAMI ALERT!
Magnitude 7.4 earthquake hits off Japan coast
TOKYO – Japan was rattled by a strong aftershock and tsunami warning Thursday night nearly a month after a devastating earthquake and tsunami flattened the northeastern coast.
The Japan meteorological agency issued a tsunami warning for a wave of up to one meter. The warning was issued for a coastal area already torn apart by last month's tsunami.
Officials say Thursday's quake was a 7.4-magnitude and hit 25 miles (40 kilometers) under the water and off the coast of Miyagi prefecture. The quake that preceded last month's tsunami was a 9.0-magnitude.
Buildings as far away as Tokyo shook for about a minute.
U.S. Geological Survey gave the preliminary magnitude as 7.4 and it struck off the eastern coast 60 miles (100 kilometers) from Sendai and 90 miles (140 kilometers) from Fukushima. It was about 215 miles (345 kilometers) from Tokyo.
The depth was 25 miles (40 kilometers). Shallower quakes tend to be more destructive.
Hundreds of aftershocks have shaken the northeast region devastated by the March 11 earthquake, but few have been stronger than 7.0. |

Powerful 7.4 magnitude quake shakes Japan
TOKYO: A powerful earthquake measuring 7.4 magnitude on the Richter scale hit northeastern Japan late Thursday.
Television reports from Japan said a tsunami alert has been issued for the affected areas.
The quake, which hit at 11:32 pm Japan time (10.35 Malaysian time) is reported to have struck 66 kilometres east of Sendai.
Sendai is the city that faced the worst brunt of the tsunami following a 9 magnitude earthquake about a month ago.
According to the reports, emergency workers at the stricken Japan nuclear plant in Fukushima have been ordered to evacuate. |

Selatan Mexico pon sama dilanda gempa 
Earthquake shakes wide area of Mexico Buildings sway for several seconds, but no damage is reported
 updated 2 hours 46 minutes ago 2011-04-07T15:03:07
MEXICO CITY — A magnitude-6.5 earthquake shook a wide area of southern and central Mexico on Thursday, sending people fleeing into the streets, but there were no initial reports of damage.
The epicenter was located near the town of Las Choapas, about 370 miles southeast of Mexico City, where it swayed buildings for several seconds. In the Gulf coast state of Veracruz, people ran from their homes and school children assembled on playgrounds.
But Gov. Javier Duarte de Ochoa there was no damage near the epicenter nor in major cities in the oil-producing state.
"Veracruz is completely quiet without problems," he told state television. "It was felt all over the state, but nothing major happened. It was only a scare."
The also was temblor was felt strongly in the state of Chiapas, bordering Guatemala, where there also were no immediate reports of damage or injuries.
The U.S. Geological survey said the quake hit a depth of 104 miles. |
