Why in news?

  • Semeru volcano has erupted in Indonesia’s Eastern Java Island.

About Semeru Volcano:

  • Mount Semeru is an active volcano located in East Java, Indonesia. This volcano is also known as Mahameru, meaning “The Great Mountain” in Sanskrit.
  • It is located in a subduction zone, where the Indo-Australian plate subducts under the Eurasia plate. It is the highest mountain on the island of Java.
  • Indonesia is prone to seismic upheaval due to its location on the Pacific’s Ring of Fire.

Ring of fire region:

  • The ring of fire region in the Circum-Pacific Belt, is an area along the Pacific Ocean characterised by active volcanoes and frequent earthquakes.
  • In a large 40,000 km horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and plate movements.
  • It has 452 volcanoes (more than 75% of the world's active and dormant volcanoes) and accounts for about 90 per cent of its earthquakes.
  • The Ring of Fire is a direct result of plate tectonics:
    • The movement and collisions of lithospheric plates, especially subduction in the northern portion.
    • The western portion is more complex, with a number of smaller tectonic plates in collision with the Pacific Plate from the Mariana Islands, the Philippines, Bougainville, Tonga, and New Zealand.
