Philippines, Kanlaon Volcanic Activity and Landslide (Lahar) in Negros Island (Regions VI and VII)

On 03 June 2024 at 6:51 PM, an explosive eruption occurred at the summit vent of Kanlaon Volcano. The eruption
produced a voluminous and incandescent plume that rapidly rose to 5,000 meters above the vent and probable short
pyroclastic density currents or PDCs approximately 2 to 3 kilometers down the southern and southeastern slopes based
on IP and thermal camera monitors. The eruption lasted six (6) minutes based on the seismic record and was preceded
by a relatively strong volcano-tectonic earthquake. Reports of coarse ashfall and sulfurous odors have been reported in
communities on the western slopes of the volcano. As of present, only two weak volcanic earthquakes have been
recorded. Kanlaon has been exhibiting above background earthquake activity for the past month and has been degassing
relatively anomalous S02 that has averaged approximately 1,273 tonnes/day for the year.
In view thereof, DOST-PHIVOLCS raised the Alert Level of Kanlaon Volcano from Alert Level 1 (abnormal) to Alert Level
2 (increasing unrest). This means that there is current unrest driven by shallow magmatic processes that could eventually
lead to further explosive eruptions or even precede hazardous magmatic eruptions.
