Officials and residents of an island south of Tokyo gathered Thursday to mourn the victims of mud slides that left 39 residents dead and missing a year ago.

Typhoon Wipha hit Izu-Oshima Island on Oct. 16, 2013, triggering flash floods that ripped through town suburbs. Authorities afterward faced heavy criticism for failing to issue evacuation warnings.

On the disaster's first anniversary, a moment of silence was held for those lost. They pledged to rebuild the areas and communities damaged.
