Other active volcanoes in Indonesia


Indonesia is home to many active volcanoes, with over 120 active volcanoes located across the country. Some of the other major volcanoes in Indonesia include:

  • Mount Krakatoa – Located in the Sunda Strait between the islands of Java and Sumatra. It is infamous for its 1883 eruption, which was one of the deadliest and most destructive volcanic events in recorded history.

Why so many volcanoes in Indonesia?

  • Indonesia is located on the Pacific Ring of Fire, a horseshoe-shaped region around the Pacific Ocean where many earthquakes and volcanic eruptions occur.
  • The country has more than 120 active volcanoes, the most of any country in the world, and has experienced some of the deadliest volcanic eruptions in history.
  • The government has implemented measures to monitor and prepare for volcanic activity, but the frequent eruptions still pose a significant threat to the country’s population and infrastructure.

Back2Basics: Pacific Ring of Fire

  • It is an area located around the rim of the Pacific Ocean where several tectonic plates meet. This region is known for its high seismic and volcanic activity.
  • It is approximately 40,000 km long and is home to about 75% of the world’s active volcanoes and 90% of the world’s earthquakes.
  • The Pacific Plate, the largest tectonic plate on Earth, moves northwest and collides with smaller plates, creating a zone of subduction.
  • As the plates collide, they create friction and pressure, leading to volcanic eruptions and earthquakes.
  • The Ring of Fire includes several countries and territories such as Japan, Indonesia, Philippines, Papua New Guinea, New Zealand, and the West Coast of North and South America.
  • The region is also known for its natural resources, including geothermal energy and minerals.
