On December 26, 2004, a magnitude 9.1 earthquake shredded the fault between the Burma and Indian plates and unleashed an explosion of energy equivalent to 23,000 Hiroshima-sized atomic bombs. The resulting tsunami caused a 100-foot wave in places, and claimed more than 227,000 lives. In India’s Nagapattinam district, more than 6,000 people were killed when waves reached 16-foot heights. Shortly after the tragedy, I travelled there to document the devastation, volunteer, and help survivors rebuild.
