The Kanlaon volcano logged a reduction of monitored volcanic quakes and sulfur dioxide gas flux on Tuesday.
In an advisory it issued, the Philippine Institute of Volcanology and Seismology recorded eight volcanic quakes, from 17 on Monday, and a drop of gas emissions from 7,172 tons for the day, to 3,447 tons on August 27.
Kanlaon volcano had been “degassing increased concentrations of volcanic SO₂” this year at an average rate of 1,273 tons per day, before the eruption on June 3, 2024.
Since then, emissions have been particularly elevated at the current average of 3,295 tons per day.
Alert Level 2 remains in effect, or “increasing unrest” prevails over Kanlaon Volcano.
PHIVOLCS observed that the current monitoring parameters indicate shallow magmatic processes beneath the volcano, which are actively contributing to unrest.
This includes persistent and increasing volcanic gas emissions, ongoing volcanic earthquake activity, and swelling of the volcano’s structure.*
