About Mount Lewotobi Laki-Laki:

  • It is located on Flores Island.
  • It is a volcanic mountain situated in East Nusa Tenggara province of
    • The volcano is part of a twin-volcano system that the local residents perceive as male and female mountains.
    • The ongoing volcanic eruption has occurred at the male counterpart of the system (Lewotobi Lakilaki) while the female mountain is known as Lewotobi Perempuan.
    • The two mountains are classified as stratovolcanoes which are the most commonly occurring volcanoes around the world and are formed by the layers of lava that repeatedly oozes out of the crater. 
  • It is not uncommon for Indonesia to witness such volcanic eruptions as it is situated along the famous ‘Ring of Fire’ in the Pacific region- an encirclement dotted by active volcanoes that sit on top of vigorous tectonic plates that often collide and lead to seismic activity causing earthquakes and tsunamis. 

What are Stratovolcanoes?

  • It is a tall, steep, and cone-shaped type of volcano.
  • Unlike flat shield volcanoes, they have higher peaks.
  • They are typically found above subduction zones, and they are often part of large volcanically active regions, such as the Ring of Fire that frames much of the Pacific Ocean.
  • Strato Volcanoes comprise the largest percentage(~60%) of the Earth's individual volcanoes, and most are characterized by eruptions of andesite and dacite, lavas that are cooler and more viscous than basalt.
