Maharashtra State PSC Model Paper 4

The correct answer is Both 1 and 2.

• Distribution of Earthquakes and Volcanoes across the World
  • ​Most known volcanic activity and earthquakes occur along converging plate margins and mid-oceanic ridges.
  • It is said that nearly 70 percent of earthquakes occur in the Circum-Pacific belt.
  • Another 20 percent of earthquakes take place in the Mediterranean-Himalayan belt including Asia Minor, the Himalayas, and parts of north-west China.
  • The belts of the highest concentration are the Aleutian-Kurile islands arc, Melanesia and New Zealand-Tonga belt.

• Volcanos in India
  • ​There are no volcanoes in the Himalayan region or the Indian peninsula.
  • Barren Island is the only active volcano in the Andaman and Nicobar Islands in India. Hence statement 2 is correct
  • It is now considered an active volcano after it spewed lava and ash in 2017.
  • The other volcanic island in Indian territory is Narcondam, about 150 km north-east of Barren Island; it is probably extinct.
