1) What is Pacific Ring of Fire? Explain its relevance in the case of recent volcanic eruption in Indonesia?(250 words)

The hindu

Why this question

A recent volcano has erupted in Indonesia. From a GS1 perspective, we need to know about the ring of fire, which leads to several earthquakes and volcanoes in that region.

Key demand of the question

The question expects us to explain about Ring of Fire and discuss why it leads to occurrence of several volcanoes and earthquakes in the region.

Structure of the answer

Introduction – Explain that Pacific Ring of Fire is a horse shoe shaped basin area of pacific ocean which stretches from all the way from South America and North America to Japan and New Zealand on the other side of the ocean. it consists of continous series of oceanic trenches,volcanic arcs,volcanic belts and high tectonic plate movements.

Body

  • Discuss why ring of fire is the zone most prone to get volcanoes and earthquakes
  • Explain that Indonesia sit along the Ring of Fire region, an area where most of the world’s volcanic eruptions occur. The Ring of Fire has seen a large amount of activity in recent days, but Indonesia has been hit hard due to its position on a large grid of tectonic plates. Indonesia is at the meeting point of three major continental plates – the Pacific, the Eurasian and the Indo-Australian plates – and the much smaller Philippine plate. As a result, several volcanoes on the Indonesian islands are prone to erupting.

Conclusion – Mention that the recent volcano is also a result of this.
