Premise: One year on from the Indian Ocean tsunami, the world's grief and compassion returned to the tsunami-battered coastlines of the Indian Ocean, where at least 216,000 people lost their lives. Under a clear sky and before a gentle sea, the world commemorated those who lost their lives, in one of the worst natural disasters that the modern world has experienced.
Hypothesis: Earthquakes have the potential to generate a tsunami.
