Mix of contaminants in Fukushima wastewater, risks of ocean dumping

Nearly 10 years after the Tohoku-oki earthquake and tsunami devastated Japan’s Fukushima Dai-ichi Nuclear Power Plant and triggered an unprecedented release radioactivity into the ocean, radiation levels have fallen to safe levels in all but the waters closest to the shuttered power plant.

Fukushima: Japan will dump radioactive water into Pacific

The operator of the ruined Fukushima Daiichi nuclear power plant will have to dump huge quantities of contaminated water from the site directly into the Pacific Ocean, Japan’s environment minister has said – a move that would enrage local fishermen.

Preparing for Japan’s Next Tsunami

The Pacific plate is one of many possible tsunamigenic quake sources, and scientists believe the Nankai Trough, another subduction zone much closer to the Japanese coast than the source of 3/11, will produce a similar megaquake and tsunami within the next 30 years.
