Mount Lewotobi Laki Laki

Mount Lewotobi Laki Laki: The Mount Lewotobi Laki Laki volcano in south-central Indonesia erupted three times recently, sending an ash column 8,000 metres (26,200 feet) high, prompting authorities to expand the danger zone.

• About Mount Lewotobi Laki Laki: It is located on flores Island in East Nusa Tenggara province, Indonesia.
• Twin Volcano System: It comprises Lewotobi Laki Laki (male) and Lewotobi Perempuan (female).
• Type: Classified as a stratovolcano — the most common type, formed by repeated layers of lava oozing out of the crater.
• Ring of Fire: Indonesia lies along the Pacific Ring of Fire, an area marked by active volcanoes and tectonic activity.
• The collision of tectonic plates causes earthquakes and tsunamis.
  • What are Stratovolcanoes?

  o Shape: Tall, steep, cone-shaped volcanoes, unlike flat shield volcanoes.

  o Formation: Found above subduction zones and are part of volcanically active regions like the Ring of Fire.

  o Composition: Comprise about 60% of Earth's volcanoes, erupt andesite and dacite lavas, which are cooler and more viscous than basalt.

  • About Subduction Zones: It occur where two tectonic plates collide and one plate subducts (dives) beneath the other. Result from differences between the continental and oceanic lithospheres that make up tectonic plates.
