MANILA, Philippines – Naitala ang pagtaas sa volcanic sulfur dioxide emissions sa Bulkang Mayon, bagamat nagkaroon naman ng pagbaba sa rockfall at pyroclastic density current activities, iniulat ng Philippine Institute of Volcanology and Seismology (PHIVOLCS).
Sa advisory nitong Biyernes, Hulyo 10, sinabi ng PHIVOLCS na ito na ang ika-186 sunod na araw ng pag-aalburoto ng bulkan kung saan nagkaroon ng pagbaba sa rockfall at pyroclastic density current o PDC (uson) activity, na nagpapahiwatig ng pagbaba ng effusion ng lava mula sa summit crater.
Ngunit iniulat din ng ahensya na “volcanic SO2 degassing measured by campaign spectrometry methods in the past two days have significantly increased.”
“Volcanic SO2 flux yesterday averaged 4,569 tonnes/day and increased today, 10 July 2026, to 7,475 tonnes/day, the highest emission from Mayon recorded in the last 16 years. To compare, SO2 flux from the start of the eruption on 6 January 2026 until present averages 2,300 tonnes/day,” sinabi ng PHIVOLCS.
“Rising volcanic SO2 emissions likely forewarn of further eruptive activity at the summit crater and continued generation of volcanic hazards, the impacts of which can be worsened by the prevailing poor weather conditions over the volcano,” dagdag ng ahensya.
Nananatili ang Alert Level 3 na babala sa Bulkang Mayon. RNT/JGC
