About 267,000 people are still living in temporary housing and other makeshift facilities nationwide as Japan marks the third anniversary Tuesday of the March 2011 earthquake and tsunami in Tohoku that triggered an unprecedented nuclear crisis.

Police and other authorities continue to search coastal areas for people still listed as missing after the 9.0-magnitude Great East Japan Earthquake — one of the most powerful temblors on record — and subsequent tsunami left thousands dead, unaccounted for, or homeless.

After the offshore quake struck at 2:46 p.m., tsunami engulfed large parts of the northeast coast, forcing the evacuation of up to about 470,000 people.
