  • The volcano has moved away from the Hawaiian hotspot.
  • Many reaching the volcano's summit complain of altitude sickness due to the sudden spike in altitude from sea level.

  • Inside an active volcano, molten rock, or magma, gets collected.
  • When the pressure increases inside, the magma moves up and comes out as lava.
  • The lava flows slowly and steadily till it cools and hardens.
  • Depending on the viscosity of the magma, they can be classified as shield volcanoes.
  • When lava spreads at a greater distance from the source and forms gentle slopes, it is a shield volcano.
