The disaster at the Fukushima nuclear power plant in 2011 was the worst such catastrophe since the 1986 Chernobyl disaster. These sorts of nuclear accidents are so incredibly serious for a bunch of reasons.

For another thing, the area of the disaster gets contaminated to such deadly levels that it becomes extremely difficult, if not impossible, for repair crews to seal up the radioactive leaks. Finally, the areas around the site can remain radioactive for hundreds or thousands of years.
So news of the recent earthquake near Fukushima and the resulting tsunami has certainly been alarming. More on page two.
