The one that's closest to us -- Mt. Merapi (intro)

Hi to all!

Firstly we shall look at Mt Merapi in Indonesia... which actually erupted last year.

Some statistics of the volcano:
  • Height: 2,914 metres
  • Location: Central Java, indonesia --> part of the Ring of Fire
  • Type of volcano: stratovolcanoes
  • Type of eruption: peleean (lateral blast)

Reasons why it is so dangerous (outlines):
  • Periodic collapse of the lava dome results in the formation of nuee ardentes (more than any volcanoes on earth) and lahars --> main hazards
  • Close proximity to densely populated areas -- 30km from Yogyakarta; rural villages located right at the foot of Merapi --> hence the hazards affect people DIRECTLY
  • Mindset of the people - their unwillingness to evacuate despite the warnings issued by government

** for the next post we shall look at the formation of Mt Merapi and take a closer look at the more recent eruption (ie 2006)

stay tune(:!
