6 volcanic quakes in 24 hours at Kanlaon — Phivolcs
Kanlaon Volcano remains on Alert Level 3 due to magmatic unrest, with Phivolcs recording six volcanic earthquakes in the past 24 hours.
The volcano emitted 2,078 tons of sulfur dioxide and a 200-meter-high plume that drifted west and southwest.
Its edifice remained inflated, suggesting continued pressurization within the volcano.
Phivolcs had previously recorded a significant increase in volcanic earthquakes, totaling 135 since Sunday morning, with magnitudes ranging from 0.3 to 3.1 and depths of 0 to 8 kilometers.
This activity suggests progressive rock fracturing caused by rising magma or gases.
A moderate eruption occurred on Tuesday, May 13, lasting five minutes, and a prior eruption on April 8 produced a 4,000-meter-tall plume.
