About Mt Semeru volcano:

• It is an active volcano in East Java, Indonesia.
• It is located in a subduction zone, where the Indo-Australia plate subducts under the Eurasia plate.
• It is the highest mountain on the island of Java.
• The name “Semeru” is derived from Meru, the central world mountain in Hinduism, or Sumeru, the abode of gods.
• Indonesia sits on the Pacific Ring of Fire, where the meeting of continental plates causes high volcanic and seismic activity.

Key points about Pacific Ring of Fire

• It also known as the Circum-Pacific Beltis a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes.
• Its length is approximately 40,000 kilometres.
• It traces boundaries between several tectonic plates—including the Pacific, Juan de Fuca, Cocos, Indian-Australian, Nazca, North American, and Philippine Plates.

Q1) What is the subduction zone?

A subduction zone is a geological boundary where two tectonic plates converge, and one plate is forced beneath the other into the Earth’s mantle. Subduction zones are some of the most geologically active and dynamic regions on the planet and are associated with various geological phenomena, including earthquakes, volcanic activity.
