what caused the tsunami in the indian ocean
2004 Indian Ocean earthquake and tsunami The 2004 Indian Ocean earthquake occurred at 00:58:53 UTC on 26 December with the epicentre off the west coast of Sumatra, Indonesia. The shock had a moment magnitude of 9.1–9.3 and a maximum Mercalli intensity of IX (Violent). The undersea megathrust earthquake was caused when the Indian Plate was subducted by the Burma Plate and triggered a series of devastating tsunamis along the coasts of most landmasses bordering the Indian Ocean, killing 230,000–280,000 people in 14 countries, and inundating coastal communities with waves up to 30 metres (100 ft) high. It was one of the deadliest natural disasters in recorded history. Indonesia was the hardest-hit country, followed by Sri Lanka, India, and Thailand.
List of disasters by cost The costs of disasters vary considerably depending on a range of factors, such as the geographical location where they occur. When a disaster occurs in a densely populated area in a wealthy country, the financial damage might be huge, but when a comparable disaster occurs in a densely populated area in a poorer country, the actual financial damage might be relatively small, in part due to a lack of insurance. For example, the 2004 Indian Ocean earthquake and tsunami, with a death toll of over 230,000 people, cost a 'mere' $15 billion,[1] whereas in the Deepwater Horizon oil spill, in which 11 people died, the damages were six-fold.
