Mount Ruang

  • About: It is located in the North Sulawesi Province, prone to regular volcanic activity.
  • Geological Structure: Stratovolcanoes like Mount Ruang are characterized by their conical shape and steep slopes.
  • First Eruption: 1808


Volcanic Eruptions

  • About: It is an opening in the earth’s surface that allows magma, volcanic ash, and gases to escape. They form at tectonic plate boundaries or hotspots.
  • Process of Eruption: Volcanic eruption occurs when gas and/or lava are released from a volcano, sometimes explosively, due to pressure buildup.
  • Environmental Benefits: Volcanoes offer environmental benefits such as fertile soils, hydrothermal energy, and valuable minerals due to volcanic activity.
  • Hazards Associated: Volcanic hazards include ash clouds, gases, lahars (mud flows), landslides, lava flows, and pyroclastic flows (hot gas currents).
  • Deadly Consequences: Volcanic eruptions can be deadly, causing population displacement, food shortages, and significant loss of life.
