摘要：Imagine a 9.0-magnitude undersea megathrust earthquake, one of the five largest ever recorded,
followed by a 128-foot tsunami that traveled up to six miles inland, followed by a level 7 nuclear
accident, in one 24-hour period. On March 11, 2011, that is precisely what happened on the northern
shore of Japan's Honshu Island, leaving an estimated 4.4 million people without electricity and 1.4
million without water.
