Kanlaon Volcano spews ash anew on Christmas Eve —PHIVOLCS

Kanlaon Volcano resumed emitting ash on Tuesday, Christmas Eve, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS).

"Ash emission from the summit of Kanlaon Volcano resumes at 11:37AM and is still ongoing, generating a dark plume 1200 m tall that is expected to rain ash over the south and southwest sectors of the volcano," PHIVOLCS said in a Facebook post past 12 p.m. Tuesday.

In an update, state volcanologists said the ash emission from the volcano ended at 11:48 a.m.

Last Monday, PHIVOLCS issued a notice of increased volcanic ash emission at Kanlaon Volcano after the volcano continuously spewed dark ash.

Kanlaon Volcano had a total of four ash emission events that lasted up to four hours and 35 minutes on Monday, according to PHIVOLCS.

A voluminous plume reaching up to 1,200 meters tall and a continuous degassing with occasional ash emission were observed from the volcano.

Twenty-five volcanic earthquakes including four very weak volcanic tremors were recorded over the volcano, which also lasted up to four hours and 35 minutes. This is higher compared to the 15 volcanic earthquakes reported on Sunday.

Kanlaon Volcano emitted 2,200 tons of sulfur dioxide gas on Monday, which is lower compared to the 7,198 tons recorded the day before.

The volcano's edifice is still inflated, according to PHIVOLCS.

Alert Level 3 is maintained over Kanlaon Volcano, which means there is a high level of volcanic unrest. Magmatic intrusion to shallow levels of the edifice is driving unrest, with indications that hazardous eruption could occur in weeks.

Possible hazards from the volcano include sudden explosive eruption, lava flow or effusion, ashfall, pyroclastic density current (PDC), rockfall, and lahars during heavy rains.

Its danger zone was expanded to a radius of six kilometers from the summit crater or active vent. — VDV, GMA Integrated News
