Kanlaon Volcano Erupts, Ashfall Expected in Nearby Communities
MANILA, Dec 23 (Bernama-PNA) — A dark plume about 1.2 kilometres high was observed in Kanlaon Volcano, the Philippine News Agency reported, citing the Philippine Institute of Volcanology and Seismology (Phivolcs) Monday.
Ash Emission and Earthquake
The ash emission began at 11.45 am, accompanied by a low-frequency volcanic earthquake, Phivolcs said.
Warning Issued
In its advisory, Phivolcs warned that ashfall is expected over communities northwest to west of the volcano in Negros Occidental.
Volcanic Parameters
While other volcanic parameters remain elevated, they have not shown significant changes.
Alert Level 3
Kanlaon Volcano has been under Alert Level 3 (magmatic unrest) since Dec 9, indicating an increased likelihood of sudden, stronger explosive eruptions that could pose life-threatening hazards to nearby communities.
Evacuation Order
Communities within a six-kilometre radius of the summit crater must remain evacuated due to the danger of pyroclastic density currents or PDCs, ballistic projectiles and ashfall, lava flows, rockfalls and other related hazards.
Heavy Rainfall
Phivolcs also highlighted the potential for heavy rainfall to trigger lahars and sediment-laden streamflow in channels on the southern flanks of the volcano.
Specific Areas at Risk
"Specifically, barangays of La Castellana and Canlaon City that have been impacted by PDCs, as well as barangays downstream of these especially those that have experienced lahars and muddy streamflows in June 2024, could be affected by channel-confined lahars of in case of heavy rains," Phivolcs said.
Aviation Warning
Phivolcs urged aviation authorities to advise pilots to avoid flying near Kanlaon’s summit, as ash from a sudden eruption could endanger aircraft.
Conclusion
The Kanlaon Volcano eruption is a serious concern, and authorities are taking necessary precautions to ensure the safety of nearby communities. Residents are advised to follow evacuation orders and take necessary precautions to avoid any potential hazards.
