How long did the tsunami in 2004 last?
Over the next seven hours, a tsunami—a series of immense ocean waves—triggered by the quake reached out across the Indian Ocean, devastating coastal areas as far away as East Africa. Some locations reported that the waves had reached a height of 30 feet (9 metres) or more when they hit the shoreline.
How was the 2004 tsunami caused?
The tsunami from the 2004 M=9.1 Sumatra-Andaman earthquake was primarily caused by vertical displacement of the seafloor, in response to slip on the inter-plate thrust fault (see Tectonics section above). The other, the local tsunami, travelled towards Indonesia, Thailand, and nearby islands in less than an hour.
Did the 2004 tsunami hit Taiwan?
Quake on anniversary of tragedy The quakes hit on the second anniversary of a massive earthquake off Indonesia that triggered a powerful tsunami in the Indian Ocean which killed 230,000 people in a dozen countries. The quake was felt throughout Taiwan, the bureau said.
What was the size of the 2004 tsunami?
The waves travelled at speeds of up to 800km/h (500mph). Computer modelling after the tsunami, estimated that waves had reached a height of almost 20m (65ft) in some areas. However, scientists investigating damage in Aceh, Indonesia found subsequent evidence that waves had reached 20-30m (65-100ft) in places.
Was the 2004 tsunami the worst ever?
Communities along the surrounding coasts of the Indian Ocean were devastated, and the tsunamis killed an estimated 227,898 people in 14 countries, making it one of the deadliest natural disasters in recorded history.

earthquake: Tsunamis. The most destructive tsunami ever recorded occurred on December 26, 2004, after an earthquake displaced the seabed off the coast of Sumatra, Indonesia.
How did the 2004 Sumatra Andaman earthquake generate a tsunami?
A more complete analysis of the focal mechanicsm by Tsai et al. (2005) indicates that oblique motion occurred on the northern part of the fault rupture. When nearly all of an earthquake’s energy is released in a thrust motion, as in the 2004 Sumatra-Andaman earthquake, a large tsunami is generated.
How did World Vision respond to the tsunami in 2004?
In response to the 2004 Indian Ocean earthquake and tsunami, World Vision mounted its largest-ever relief response across five countries simultaneously — Indonesia, Sri Lanka, Thailand, India, and Myanmar — and raised more than $350 million.
