VOLCANOES IN INDONESIA
Indonesia is located on the Pacific Ring of Fire.
- The Ring of Fire, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes.
- Its length is approximately 40,000 kilometers. It traces boundaries between several tectonic plates—including the Pacific, Cocos, Indian-Australian, Nazca, North American, and Philippine Plates.
- 75% of Earth’s volcanoes i.e. more than 450 volcanoes are located along the Ring of Fire. 90% of Earth’s earthquakes occur along its path, including the planet’s most violent and dramatic seismic events.
- The abundance of volcanoes and earthquakes along the Ring of Fire is caused by the amount of movement of tectonic plates in the area.
