Japan Marks One Month Since Earthquake

The nuclear crisis and rebuilding efforts drag on as aftershocks keep Japan on edge.

Japan marked on Monday the one-month anniversary of the massive earthquake and tsunami that devastated the country's northeast coast and plunged the world into its worst nuclear crisis since Chernobyl in 1986. Just as Prime Minister Naoto Kan was about to deliver a speech commemorating the month, another 6.6-magnitude aftershock shook the northeast, prompting another tsunami alert and the temporary evacuation of the stricken Fukushima Daiichi nuclear plant. Kan had published a letter in newspapers around the globe thanking the world for its response to the crisis. More than 28,000 people have died in what is believed to be the world's costliest natural disaster of all time.
