People are seen through a hole in the wall of a damaged building, as they visit a giant steel barge that housed a diesel power generator swept ashore by the Indian Ocean tsunami ten years ago, in Banda Aceh, Aceh province, Indonesia, Friday, Dec. 26, 2014. The devastating Boxing Day tsunami in 2004 struck a dozen countries around the Indian Ocean rim, killing 230,000 people, most of them in Aceh. The power plant is now a major tourist attraction in the provincial capital.
