Kanlaon depicts signs of increased volcanic activity

MANILA – The Philippine Institute of Volcanology and Seismology (Phivolcs) reported on Friday that the Kanlaon Volcano in Negros Island is showing signs of increased activity.

Phivolcs stated in an advisory that 18 volcanic earthquakes were logged in the last 24 hours. The number includes four “very shallow tornillo signals” associated with magmatic gas along fractures within the upper volcanic slopes.

Since mid-October of last year, Phivolcs has also noticed slight deformation of the edifice.

“The increased seismic activity and short-term ground deformation are likely caused by shallow hydrothermal processes beneath the edifice that could generate phreatic or steam-driven eruptions from the summit crater,” it added.

Volcanic quakes are created by the magma movements or eruptions from the volcano. On the other hand, shallow tornillo signals are low-frequency earthquake that have the shape of a tornillo or a screw.

Last January 16, weak to moderate and low steam-laden plumes exceeding 200 meters high were observed.

Alert Level 1 (abnormal) is maintained over the Kanlaon Volcano.

Phivolcs said that entry into the 4-kilometer radius permanent danger zone must be strictly restricted due to possibilities of sudden steam-driven or phreatic eruptions.

Moreover, pilots are advised to avoid getting near the summit of the volcano as phreatic eruption can be hazardous to aircraft.
