ters high.

At least 150,000 people are known to have died as a result of the tsunamis. The final toll may never be known due to bodies swept out to sea, but is likely to be considered much higher.  There is a possibility to be many more deaths due to dieses and starvation.

Power of the Earthquake: It was the second biggest earthquake ever recorded on a seismograph with a magnitude of 9.1 to 9.3.

PictureTsunami characteristics: The earthquake triggered massive tsunamis that struck the coasts of the Indian Ocean, the deadliest tsunamis by far in all of recorded history.

How do earthquakes occur: Most earthquakes occur along the edge of the oceanic and continental plates.  The earth's crust (the outer layer of the planet) is made up of several pieces, called plates


The plates under the oceans are called oceanic plates and the rest are continental plates. The plates are moved around by the motion of a deeper part of the earth that lies underneath the crust. These plates are always bumping into each other pulling away from each other, or past each other. Earthquakes usually occur where two plates are running into each other or sliding past each other.
