Indonesia is part of the so-called "Pacific Ring of Fire" (powerful tectonic fault). Plate, forming the bottom of the Indian Ocean, "squeezes" here under the Asian plate, which is part of Sumatra, about as fast as the growing human fingernail. Accumulating tension and then released as a giant earthquake forces.
It is on the north-west of Sumatra in December 2004 struck one of the first hit the hardest in the world for the last 40 years of the earthquake that caused a tsunami that killed hundreds of thousands of people in 12 countries of the Indian Ocean.
