Kanlaon shows intensified unrest; PHIVOLCS raises alert to Level 3

At least 16 volcanic earthquakes, including six volcanic tremors lasting between 49 and 84 minutes, were recorded at Kanlaon Volcano in Negros Island over the past 24 hours.

PHIVOLCS also reported two ash emission events that lasted for 43 to 49 minutes, a plume reaching up to 1,200 meters tall drifting westward, and an emission of 3,984 tonnes of sulfur dioxide on Saturday, December 28.

Kanlaon continues to show 'intensified unrest' under Alert Level 3 with signs indicating that a hazardous eruption could occur within weeks due to magmatic intrusion at shallow levels.

Taal Volcano remains under alert level 1 (low level of volcanic unrest) and has emitted 1,181 metric tons of sulfur dioxide gas during the latest observation period on Friday.

PHIVOLCS advises evacuating residents within six kilometers of Kanlaon's summit and prohibiting aircraft flights near both volcanoes due to potential hazards such as sudden explosive eruptions, lava flows, ashfall, pyroclastic density currents (PDCs), rockfalls, and lahars during heavy rains.
