Mayon's sulfur dioxide surge raises fresh eruption concerns

The Philippine Institute of Volcanology and Seismology (Phivolcs) issued an advisory Friday after detecting SO2 emissions from Mayon's summit crater reaching 8,165 tonnes, marking a significant spike in volcanic gas concentrations.

The elevated sulfur dioxide readings represent the second-largest emission event recorded since gas concentrations began their declining trend in July. Scientists have long monitored SO2 levels as a key indicator of subsurface magma movement and potential volcanic unrest.

Phivolcs warned that the surge in emissions raises the possibility of renewed eruptive activity at the volcano, which sits in Albay province on the island of Bicol. The alert underscores the importance of continued monitoring as volcanic activity remains unpredictable.

The latest development comes as authorities maintain heightened surveillance of the volcano. Residents and officials in nearby communities have been advised to remain vigilant and prepared for potential changes in volcanic behavior.

Phivolcs continues to closely track Mayon's volcanic parameters, including seismic activity, ground deformation, and gas emissions, to provide timely updates to the public and local government units.
