About Mount Marapi

  • It is a volcanic mountain peak located near the centre of the island of Java, Indonesia. 
  • Marapi’s name is derived from the ancient Mignangkabau dialect meaning “Mountain of Fire '' it seems likely this complex volcano has been highly active for thousands of years.
  • It rises to 9,551 feet (2,911 metres) and has steep slopes with dense vegetation on its lower flanks.
  • Marapi is among more than 120 active volcanoes in Indonesia, which is prone to seismic upheaval due to its location on the Pacific “Ring of Fire,” an arc of volcanoes and fault lines encircling the Pacific Basin.

Key points about the Pacific Ring of fire

  • It is also known 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 kilometres (24,900 miles).
  • 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 a stratovolcano?

It is also called a composite volcano. This volcanic landform is characterized by a conical shape formed by layers of volcanic material deposited during successive volcanic eruptions. These volcanoes tend to slope gently at the base but rise quickly near the summit to form tall mountain peaks.
