A Japanese survivor of the earthquake and tsunami rides his bicycle through the leveled city of Minamisanriku, in northeastern Japan, Tuesday March 15, 2011. First a 9.0 earthquake_the fifth largest since 1900_ struck off of the coast of northern Japan. The trembler brought a devastating tsunami that obliterated town after town along the coastline. The quake and tsunami crippled the Fukushima Dai-Ichi nuclear reactors contaminating a vast area around it. After Japan's triple disaster, more than 25,000 people are dead or missing, hundreds of thousands are homeless, and the severity of the nuclear reactor has been raised to level 7, the highest level possible, ranking it the same as Chernobyl.
