A decade since a tsunami killed 230,000 people in Southeast Asia, the United Nations' top official for dealing with natural disasters said the world must do more to prepare for extreme weather, AP reported. Margareta Wahlstrom, the special representative of the U.N. secretary-general for disaster risk reduction told The Associated Press on Tuesday the world is better prepared for calamities of the scale of the massive earthquake on Dec. 26, 2004 that triggered a 100-foot-high tsunami which spread death across a dozen countries.
