On March 11th, 2011, the Fukushima Daiichi nuclear power plant complex suffered damage from an earthquake and ensuing tsunami that caused multiple nuclear reactor core meltdowns and melt-throughs, explosions, and major releases of radioactive material into the air and the sea. In addition to the reactor meltdowns and melt-throughs spent fuel storage tanks were also…

Nature Update on Fukushima

Almost exactly one year ago, a very large double strength tsunami struck the Pacific Coast of Japan and washed a huge amount of stuff out into the sea. The oceanic born debris of terrestrial origin looked in places like this: source Subsequently attempts were made to model the movement of the debris in the Pacific.…
