On March 11, 2011, a magnitude-9 earthquake shook northeastern Japan, unleashing a tsunami.
Four years after the quake, about 230,000 people who lost their homes were still living in temporary housing, Japan’s Reconstruction Agency said. More than 16,000 people were killed and 2,500 remain missing. The total damage from the earthquake and tsunami are estimated at $300 billion, according to the Japanese government.
