More than 100 evacuation sites designated by local governments were swept away or inundated by the tsunami triggered by the March 11 earthquake just off the Tohoku region's coast, according to a tally compiled by Kyodo News.

Many people are thought to have lost their lives after fleeing to those sites, believing they would be safe, but no data have so far been collected on the death toll at those places.

There have been no moves so far among citizens to hold local governments responsible for designating those sites, apparently because the scale of the tsunami was beyond what had been foreseen.
