Kanlaon Volcano in Negros Island generated a low-energy phreatic (steam-driven) eruption at 09:47 AM today, 09 December 2017. The eruption lasted approximately ten (10) minutes based on the seismic record. The event ejected steam and dark ash but was poorly observed due to clouds covering the summit region. Rumbling sound was reportedly heard in Brgy. Manghanoy, La Castellana, and thin ash fell on Sitio Guintubdan, Brgy. Ara-al, La Carlota City. Notably, today’s eruption was preceded by resumption of degassing at the summit crater at 06:34 AM, which was last observed September 2016.

Alert Level 2 status prevails over Kanlaon Volcano, which means that the volcano is undergoing a moderate level of unrest. There is probable intrusion of magma at depth which may or may not lead to a magmatic eruption. The local government units and the public are strictly reminded that entry into the 4-kilometer radius Permanent Danger Zone (PDZ) is strictly prohibited due to the further possibilities of sudden and hazardous steam-driven or phreatic eruptions. Civil aviation authorities must also advise pilots to avoid flying close to the volcano’s summit as ejecta from any sudden phreatic eruption can be hazardous to aircraft. DOST-PHIVOLCS is closely monitoring Kanlaon Volcano’s activity and any new development will be relayed to all concerned.
