where and when was the tsunami that caused the most casualties
2004 Indian Ocean earthquake and tsunami According to the U.S. Geological Survey a total of 227,898 people died (see table below for details).[1] Measured in lives lost, this is one of the ten worst earthquakes in recorded history, as well as the single worst tsunami in history. Indonesia was the worst affected area, with most death toll estimates at around 170,000.[100] However, another report by Siti Fadilah Supari, the Indonesian Minister of Health at the time, estimated the death total to be as high as 220,000 in Indonesia alone, giving a total of 280,000 fatalities.[8]
2004 Indian Ocean earthquake and tsunami Because of the distances involved, the tsunami took anywhere from fifteen minutes to seven hours to reach the coastlines.[46][47] The northern regions of the Indonesian island of Sumatra were hit very quickly, while Sri Lanka and the east coast of India were hit roughly 90Â minutes to two hours later. Thailand was struck about two hours later despite being closer to the epicentre, because the tsunami traveled more slowly in the shallow Andaman Sea off its western coast.
