Tsunami

The country's safety culture needed updating to prevent a Fukushima-type disaster.

Japan's latest response to the Fukushima radiation leak sounds like science fiction: A wall of ice. Ice walls are common in tunneling; it's the radiation that makes this job different.

Today's anniversary is being marked with protests against nuclear power in Japan. But can the country sustain a non-nuclear energy policy?

A 7.3 magnitude earthquake has struck off the coast of Japan. While there are no reports of significant damage, how are the Japanese responding a year and a half after the country's previous tsunami disaster?

A Japanese government report on the Fukushima nuclear crisis puts the blame squarely on culture -- namely, a cozy relationship between politicians, regulators and the nuclear power industry. It goes so far as to suggest the accident might have occurred even without an earthquake and tsunami.

And no one has clue who will pay for the clean-up of tons of debris.

There are tsunami watches and warnings around the Indian Ocean this morning after a magnitude 8.6 quake struck off the coast of Indonesia early today.
