Kanlaon Volcano, situated in the Philippines, is showing signs of heightened unrest, prompting concerns from authorities.
According to the Philippine Institute of Volcanology and Seismology (PHIVOLCS), a surge in seismic activity was recorded starting Thursday morning. The volcano experienced 64 volcano-tectonic (VT) earthquakes, significantly higher than the six recorded on Wednesday.
Increased Seismic Events: A Cause for Concern
These VT earthquakes, ranging in magnitude from ML0.9 to ML2.9, occurred at depths between 2 and 8 kilometers beneath Kanlaon’s western flanks. PHIVOLCS attributes VT earthquakes to rock fracturing processes, suggesting that rising magma may be pushing through cracks beneath the volcano’s surface.
Sulfur Dioxide Emissions Also Rise
Adding to the concerns, volcanic sulfur dioxide (SO2) emissions from Kanlaon Volcano significantly increased. On Wednesday, emissions reached 7,087 tons, surpassing the 4,234 tons daily average observed since the eruption in June.
Prior to the eruption, Kanlaon’s SO2 emissions averaged 1,273 tons/day. Since the eruption, emissions have remained elevated.
Alert Level 2 Remains in Effect
While Alert Level 2 remains in effect for Kanlaon Volcano, PHIVOLCS warns that the ongoing seismic activity could lead to further unrest and a possible elevation of the alert level. Alert Level 2 indicates an increased unrest, suggesting the possibility of sudden steam-driven or phreatic eruptions.
Authorities strongly advise against entering the four-kilometer radius Permanent Danger Zone (PDZ) surrounding Kanlaon and prohibit aircraft flights in the vicinity.
