Kanlaon Volcano Lahars Follow Intense Rains
Lahars, the dangerous muddy flows made of volcanic ash, debris, and water, were reported on the southern and southwestern slopes of Kanlaon Volcano late Friday, June 6. This happened after heavy rains soaked parts of Negros Island, local sources said.
These sediment-filled flows appeared along the Buhangin River and Ibid Creek in La Castellana, Negros Occidental, following 45.5 millimeters of rain in just 3.5 hours. Residents and officials took to social media to report the cohesive, cement-like lahars near Hacienda 92 Bridge in Brgy. Sag-ang and in Brgy. Biak-na-bato.
Weather Conditions Fuel Kanlaon Volcano Lahars
The low pressure area (LPA) combined with the southwest monsoon has been bringing moderate to heavy rainfall over the region, including the upper slopes of Kanlaon Volcano. According to weather advisories, these conditions have worsened the risk of lahars.
While rainfall measured at Kanlaon Volcano Observatory in La Carlota City was 45.5 mm, it is likely that rain near the summit was even heavier, contributing to the sediment flows. The persistent monsoon rains are expected to continue, increasing the possibility of more lahars in the coming months.
Community Warnings and Preparedness
Authorities warn that lahars and muddy streamflows can threaten communities along the middle and lower slopes of Kanlaon Volcano. These flows may cause flooding, bury homes, or wash out roads and bridges.
Residents near affected rivers are urged to stay alert, especially when heavy rains begin, as rainfall remains the best early-warning sign for lahars. Local leaders and communities are encouraged to prepare and respond swiftly to protect lives and property.
