On 4 November 2024, the volcano spewed molten debris at several villages some 4 km (2.5 mi) away, destroying homes and killing at least nine. [74] The Centre of Volcanology and Geological Hazard Mitigation recommended that a 7 km (4.3 mi) radius around the volcano be evacuated. [75] Seven villages were affected by the eruption. [76]
These levels reflect conditions at a volcano and the expected or ongoing hazardous volcanic phenomena. When an alert level is assigned by an observatory, accompanying text will give a fuller explanation of the observed phenomena and clarify hazard implications to affected groups. Both ground and aviation alerts are provided for volcanoes in the ...
On December 9, PHIVOLCS raised the alert level of Kanlaon from level 2 to level 3 after an explosive eruption occurred at the summit vent at 3:03 p.m. The eruption produced a large plume that rose 4,000 m (13,000 ft) above the vent and drifted west-southwest, with pyroclastic flow moving down the south-southeastern side of the volcano.
