About the recent Eruption and Historical Activity:

  • In a recent eruption, Mount Kanlaon spewed an ash plume up to 4,000 meters high, capturing national attention.
  • The eruption was phreatic in nature — a type commonly observed at Kanlaon since 1866.
  • These eruptions usually cause localized ashfall, posing risks to nearby communities and air travel.
  • Its activity reaffirms its reputation as one of the most active volcanoes in the Philippines.

Ecological and Hydrological Importance

  • Beyond its geological significance, Kanlaon is a biodiversity hotspot, home to many endemic plant and animal species.
  • Its forested slopes act as natural watersheds, supporting major rivers across Negros Island.
  • The area is under close volcanological monitoring due to its dual role as a natural wonder and hazard.
