How deep was the 2004 Indonesian earthquake?

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.

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.
