Kanlaon Volcano’s seismic monitoring network recorded five (5) volcanic earthquakes during the past 24 hours. Two (2) low-energy ash eruptions from the active summit crater were visually observed. However these events were not detected by the seismic network, indicating a shallow volcanic source. The first ash eruption occurred at 9:51 AM, producing light gray ash clouds which reached 100 meters above the summit before slowly drifting southwest. A second ash eruption occurred at 10:08 AM, producing light gray ash clouds which reached 200 meters above the summit and again slowly drifted southwest. Traces of ash were reported at Sitio Bais, Brgy Yubo, La Carlota City on the western slopes of Kanlaon Volcano. Background activity was characterized by the emission of wispy to moderate emission of light gray steam plumes that rose up to 200m from the summit and drifted to the southwest.
Alert Level 1 status remains in effect over Kanlaon Volcano, which means that it is at an abnormal condition and is in a period of current unrest. The local government units and the public are reminded that entry into the 4-kilometer radius Permanent Danger Zone (PDZ) is strictly prohibited due to the further possibilities of sudden and hazardous steam-driven or phreatic eruptions. Civil aviation authorities must also advise pilots to avoid flying close to the volcano’s summit as airborne ash from a sudden eruption can be hazardous to aircraft. DOST-PHIVOLCS is closely monitoring Kanlaon Volcano’s activity and any new development will be relayed to all concerned.
