CaptionA woman mourns a relative killed in the tsunami. On December 26, a 9.3 magnitude earthquake off the coast of Sumatra, Indonesia, triggered a series of deadly waves that traveled across the Indian Ocean, wreaking havoc in nine Asian countries, and causing fatalities as far away as Somalia and Tanzania. The quake was so strong that it altered the tilt of the planet by 2.5cm. More than 200,000 people died or were reported missing, and millions were left destitute in the worst natural disaster in living memory. In India, the fishing communities in Tamil Nadu were among the worst hit, with homes, lives and livelihoods being wiped away.
