Japan will mark the 10th anniversary of the 2011 earthquake, tsunami and nuclear disaster, on Thursday, March 11, 2021. ___2.4% OFF-LIMITSA decade after the disaster, no-go zones remain in nine Fukushima municipalities surrounding the wrecked nuclear plant. Ad___14 MILLION TONS OF RADIOACTIVE WASTEAbout 14 million tons of radioactive soil, trees and other waste from decontamination efforts across Fukushima are packed in massive numbers of plastic waste bags piled at temporary storage sites. The bags, enough to fill 11 enclosed baseball stadiums, are now being transported to a medium-term storage facility being built in the two towns that are home to the Fukushima nuclear plant. The operator, TEPCO, says the tanks currently contain 1.24 million tons of water and will be full in the fall of 2022.

Japan on Thursday marked the 10th anniversary of the massive earthquake, tsunami and nuclear disaster that struck Japan's northeastern coast. Emperor Naruhito and Prime Minister Yoshihide Suga were among those observing a moment of silence at a memorial in Tokyo. More than 18,000 people died, mostly in the tsunami, and nearly half a million people were displaced. The government recognizes another 3,700 — mostly from Fukushima prefecture — who died of causes linked to the disaster, such as stress. Thursday's ceremony comes just two weeks before the Olympic torch relay begins from Fukushima for the delayed Tokyo Summer Games in July.

The Japan Meteorological Agency says a strong earthquake has hit off the coast of northeastern Japan, shaking Fukushima, Miyagi and other areas. (Keiko Hatto via AP)TOKYO – A strong earthquake hit off the coast of northeastern Japan late Saturday, shaking Fukushima, Miyagi and other areas, but there was no threat of a tsunami, officials said. He said that some trains in northeastern Japan had stopped running, and that other damage was still being checked. Items fell off shelves because of the shaking, NHK said. The same northeastern area was slammed by a quake, tsunami and nuclear disaster in March 2011.

The contaminated water, a mixture of injected cooling water and groundwater that flows into the reactor area, has accumulated since the accident. The government and TEPCO say water treatment systems can remove all but water-soluble tritium, though currently 70% of the water contains other radioactive materials exceeding allowable limits. Suga visited the Fukushima plant last month and said he hoped to make a decision as soon as possible. Nuclear officials inside and outside of Japan have said a controlled release of the water into the ocean is the only realistic way of getting rid of the water safely. But some scientists say the long-term environmental impact from radioactive water is unknown and could pose higher risks than explained.

From 1946 to 1958, the US government conducted 67 nuclear tests on several small islands -- called atolls -- in the Marshall Islands. Analyzing soil samples, researchers found concentrations of Am-241, Cs-137, Pu-238, and Pu-239,240 on 11 islands across the four northern atolls. The population of the Marshall Islands is relatively small, with just over 75,000 people living on the chains as of July 2018. It is a combination of islands and atolls, which are usually circular islands ringing a wide lagoon or coral reef. In Rongelap atoll, researchers found that northern Naen island had the highest levels of external gamma radiation of all islands examined in the study -- well above the legal exposure limit agreed between the Republic of the Marshall Islands and the US.
