KANLAON VOLCANO BULLETIN 30 March 2016 8:00 A.M.
[Issued by Philippine Institute of Volcanology and Seismology – PHIVOLCS]
Two (2) minor eruption events occurred at Kanlaon Volcano’s active crater at around 6:20 PM and 7:18 PM of 29 March 2016 that lasted around 12 minutes and 25 seconds, respectively, based on visual observation and seismic recording. These events were recorded by the Kanlaon Seismic Network as explosion-type earthquakes. The first event was accompanied by a booming sound heard in Sitio Guintubdan, Brgy. Ara-al and Brgy. Yubo, La Carlota City, Negros Occidental and Brgy. Pula Canlaon City, Negros Oriental. From the southeastern side of the volcano, the eruption plume was observed to have reached 1500 meters above the active crater. Incandescent ejecta apparently caused small bushfire at the upper slope as observed from La Castellana. Traces of light ashfall were reported in Sitio Guintubdan, Brgy. Ara-al, La Carlota City, Negros Occidental. The eruption was followed by two episodes of volcanic tremor from 10:38 PM 29 March to 00:26 AM 30 March and from 01:30 AM this morning to present (ongoing). Continuous GPS data as of 14 March 2016 indicated slight inflation of the Kanlaon edifice since December 2015.
Alert Level 1 status remains in effect over Kanlaon Volcano, which means that it is currently in a state of unrest probably driven by hydrothermal processes that could generate more minor eruptions. The local government units and the public are 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 minor ash eruptions. Civil aviation authorities must also advise pilots to avoid flying close to the volcano’s summit as airborne ash from a sudden 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.
