Volunteers have helped to dispose of quake debris in Yamagata Prefecture after a magnitude 6.7 tremor struck off the coast of northern Japan on Tuesday.
Many tiles fell off roofs in the city of Tsuruoka, where an intensity of 6-minus on the Japanese scale of zero to 7 was registered.
Fourteen volunteers from Tsuruoka, Iwate Prefecture and Tokyo gathered at three designated sites on Sunday to help unload and sort the rubble.
A volunteer in his 40s says he wanted to do something for his hometown because it has been hit by a major disaster. A city official says they need a lot of people for the disposal work, and the volunteers are doing a great job.
