Govt expects more Fukushima nuclear waste

Japan's environment ministry says radioactive waste from last year's nuclear accident in Fukushima is likely to exceed previous estimates.

The ministry surveyed Fukushima and 8 near by prefectures, including Tokyo, on Monday. It found they are storing a total of 42,575 tons of waste containing radioactive cesium levels of more than 8,000 becquerels per kilogram.

The figure is expected to rise as officials continue testing for radioactivity. The ministry's original estimate was about 50,000 tons.

A law enacted in January says the central government is responsible for disposing of highly radioactive waste from the accident.

The 9 prefectures are storing the waste while the central government tries to secure locations for permanent disposal.

75 percent of the waste is from Fukushima Prefecture, 10 percent from Tochigi and 4 percent from Ibaraki.

Fault ruptures confirmed near Japan Trench.

Japanese scientists say they have found evidence of displacement of the tectonic plates caused by the March 11th earthquake last year.

A team from the Japan Agency for Marine-Earth Science and Technology conducted an acoustic wave study last year along the Japan Trench about 250 kilometers off the coast of Miyagi Prefecture. The study assessed the seabed structure to a depth of several kilometers.

The findings showed at least 2 displacements near the trench axis where the Pacific plate begins to sink below the plate underneath northeastern Japan.

The scientists say fault ruptures from the quake's epicenter located in the deep part of the plate boundary reached the seabed surface.

They say structural upheavals along the fault indicate BIG EARTHQUAKES HAVE OCCURRED REPEATEDLY IN THE AREA.

A senior agency official says a detailed seabed survey is needed to uncover the mechanism of massive quakes and how often they occur.
