A 9.0-magnitude quake - one of the strongest on record - and tsunami hit northeastern Japan on March 11, 2011, claiming nearly 20,000 victims, destroying towns and triggering nuclear meltdowns in Fukushima, the world's worst nuclear disaster since Chernobyl. The tsunami crippled the Fukushima Dai-ichi power plant and forced more than 160,000 residents to flee as radiation spewed into the air. The government has spent about $300 billion (32.1 trillion yen) to rebuild the tsunami-devastated region, but areas around the Fukushima plant remain off-limits, worries about radiation levels linger and many who left have settled elsewhere. On March 11 2011, a 9.0 magnitude earthquake triggered a massive tsunami that crashed into Japan's Tohoku region, an estimated 20,000 people were killed or declared missing in the wake of the disaster.
