Kanlaon stays underneath Alert Degree 2, which implies the present unrest “may ultimately result in explosive eruptions on the summit crater.”
Phivolcs reminded the general public to keep away from the 4-kilometer-radius everlasting hazard zone surrounding Kanlaon. Potential volcanic hazards embrace pyroclastic density currents or PDCs, ballistic projectiles, rockfall, and ashfall.
“In case of ashfall occasions that will have an effect on communities downwind of Kanlaon’s crater, individuals ought to cowl their nostril and mouth with a moist, clear material or mud masks,” the company stated.
