Earthquakes, volcanic eruptions and tsunamis frequently strike Indonesia, a country of more than 270 million people, because of its location on the "Ring of Fire."
The Ring of Fire, or the Circum-Pacific Belt, is a path along the Pacific Ocean characterised by active volcanoes and frequent earthquakes.
It is a horseshoe-shaped belt about 40,000km long and about 500 km wide that contains two-thirds of the world's total volcanoes and 90 per cent of Earth's earthquakes.
