The Philippine Institute of Volcanology and Seismology (Phivolcs) observed a “sustained vigorous” degassing from the summit crater of Kanlaon Volcano on Tuesday, Oct. 8.

The Kanlaon Volcano Observatory reported that the active volcano's sulfur dioxide emissions averaged 5,525 tons on Tuesday.

Since its eruption on June 3, volcanic emissions have been particularly elevated, with an average of 4,182 tons daily.

Phivolcs reminded the public that Alert Level 2 (increasing unrest) is currently in effect for Kanlaon Volcano.

Residents are advised to remain vigilant and avoid entering the four-kilometer-radius permanent danger zone to minimize risks from volcanic hazards such as pyroclastic density currents, ballistic projectiles, and rockfalls.

In the event of ash fall affecting communities downwind of Kanlaon Volcano's crater, Phivolcs said individuals should cover their noses and mouths with a damp, clean cloth or dust mask. 

Civil aviation authorities are asked to advise pilots to steer clear of the volcano summit to avoid hazards from ash and volcanic fragments.

Likewise, communities living near river systems on the southern and western slopes, especially those previously affected by lahars and muddy streamflows, are advised to take precautionary measures if heavy rainfall is anticipated or begins.
