Photos taken before and after the arrival of a massive tsunami highlight the destruction of Banda Aceh, Indonesia, on December 26, 2004. The tsunami was generated by a magnitude-9.1 earthquake that occurred only 30 metres (98 feet) beneath the floor of the Indian Ocean.
How far inland did Tsunami 2004 go?
In many places, the waves reached as far as 2 km (1.2 mi) inland. Because the 1,600 km (1,000 mi) fault affected by the earthquake was in a nearly north–south orientation, the greatest strength of the tsunami waves was in an east–west direction.
How big was the 2004 Indonesian earthquake?
The magnitude 9.1 quake ruptured a 900-mile stretch of fault line where the Indian and Australian tectonic plates meet. It was a powerful megathrust quake, occurring where a heavy ocean plate slips under a lighter continental plate.
Why was the tsunami of 2004 so deadly?
According to USGS scientists, the sea floor near the earthquake was uplifted several meters. The displacement of water above the sea floor triggered the tsunami, which caused catastrophic levels of destruction in countries around the Indian Ocean basin, reaching as far as the east coast of Africa.
What type of earthquake caused the 2004 tsunami?
Details of Tsunami Generation. 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).
Did they know the 2004 tsunami was coming?
When the Indian Ocean tsunami struck on Dec. 26, 2004, no one saw the massive waves coming. … Thai officials did send a warning, but only after the first deadly wave hit. And in India, word of the disaster went to the wrong official.
What is the biggest tsunami ever?

How long did the 2004 Indonesian earthquake last?
Indian Ocean tsunami of 2004, tsunami that hit the coasts of several countries of South and Southeast Asia in December 2004. The tsunami and its aftermath were responsible for immense destruction and loss on the rim of the Indian Ocean. did you know? The earthquake that caused the tsunami lasted almost 10 minutes.
What is the atomic bomb equivalent to a 8.0 earthquake?
|Approximate Richter Magnitude number||Seismic energy equivalent: Amount of TNT|
Is a mega tsunami real?
A megatsunami is a tsunami with an initial wave amplitude (height) measured in many tens, hundreds, or possibly thousands of metres. A megatsunami is a separate class of event from a traditional tsunami and is caused by different mechanisms. Normal tsunamis result from movement of the sea floor due to plate tectonics.
Can you swim under a tsunami?
“A person will be just swept up in it and carried along as debris; there’s no swimming out of a tsunami,” Garrison-Laney says. “There’s so much debris in the water that you’ll probably get crushed.” Eventually, the wave will pull back, dragging cars, trees, and buildings with it.
How long did it take to rebuild after the 2004 tsunami?
The results of these efforts are remarkable. Within five years, individuals were back in homes they owned, often on their original land, in communities with new schools and in many cases improved infrastructure.
How much did it cost to rebuild after the 2004 tsunami?
The disaster generated a massive aid and reconstruction program, with around 463 non-government organisations and agencies spending around $7.5 billion. This made post-tsunami Aceh one of the largest reconstruction projects in the developing world. Australian donors and the government gave more than $1 billion.
When was the last tsunami in the world?
Tsunami of January 22, 2017 (Bougainville, P.N.G.)
What earthquake magnitude can you feel?
|Magnitude||Earthquake Effects||Estimated Number Each Year|
|2.5 or less||Usually not felt, but can be recorded by seismograph.||900,000|
|2.5 to 5.4||Often felt, but only causes minor damage.||30,000|
|5.5 to 6.0||Slight damage to buildings and other structures.||500|

How many survived the 2004 tsunami?
Foreigners from 38 nations were killed by the waves that struck southern Thailand. More than 100 survivors of the tsunami along with bereaved relatives from Germany, Austria and Switzerland held a memorial service on a beach in Khao Lak, Thailand.
