It is exactly six months since the Indian Ocean tsunami, one of history’s worst natural disasters that claimed up to 232,000 lives. It was an unprecedented tragedy that triggered an unprecedented international response. Aid pledges were immense. Yet survivors in the countries worst affected – Indonesia, Sri Lanka, India and Thailand – say the reconstruction of homes and schools has barely begun. The UN believes it will take as long as a decade to rebuild what was destroyed. Memories of that fateful Sunday morning on December 26 2004 are still vivid. Tourists are gradually returning to Thailand where foreigners were among those who died.
