At 8:00 PM Monday, 3 June 2024, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) released a bulletin announcing the escalation of the alert level of Kanlaon Volcano from Alert Level 1 to Alert Level 2.
This decision follows an explosive eruption that occurred earlier in the evening, precisely at 6:51 PM, rocking the region with a six-minute burst of volcanic activity.
The eruption, originating from the summit vent of Kanlaon Volcano, unleashed a towering plume of incandescent material, reaching a staggering height of 5,000 meters above the vent. Monitoring equipment detected potential short pyroclastic density currents (PDCs) cascading down the southern and southeastern slopes, posing a potential threat to nearby communities.
Preceding the eruption was a notably robust volcano-tectonic earthquake, underscoring the heightened geological activity within the region. Reports of coarse ashfall and sulfurous odors swiftly emerged from communities situated on the western slopes of the volcano, signaling the immediate impact of the eruption.
Despite only two weak volcanic earthquakes recorded thus far, Kanlaon Volcano has exhibited above-background earthquake activity over the past month.
Additionally, the volcano has been emitting relatively anomalous levels of sulfur dioxide, averaging approximately 1,273 tonnes/day for the year, further indicating the escalating unrest within its depths.
The raised Alert Level 2 signifies an increasing unrest driven by shallow magmatic processes, potentially paving the way for further explosive eruptions or hazardous magmatic activities. With this, the public is strongly urged to exercise vigilance and steer clear of the four-kilometer-radius Permanent Danger Zone (PDZ) surrounding the volcano. This measure aims to mitigate risks stemming from sudden explosions, rockfalls, and landslides.
In the event of ashfall affecting communities downwind of Kanlaon’s crater, residents are advised to shield their respiratory systems by covering their nose and mouth with a damp, clean cloth or dust mask. Furthermore, civil aviation authorities have been cautioned to advise pilots against flying in close proximity to the volcano's summit, as airborne ash poses a significant hazard to aircraft safety.
