The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reports that Mayon Volcano in Albay shows increased volcanic sulfur dioxide (SO2) emissions. According to PHIVOLCS advisories cited by news outlets, SO2 flux rises from Thursday to Friday, with Thursday averaging about 4,569 tonnes per day and increasing to about 7,475 tonnes per day on Friday. PHIVOLCS describes the Friday level as the highest Mayon SO2 emission recorded in the last 16 years. The emissions observed since the eruption began on January 6 average about 2,300 tonnes per day. While SO2 output increases, PHIVOLCS also notes changes in other monitored activity. One report states that rockfall and pyroclastic density current activity decrease during the same period. PHIVOLCS links rising SO2 emissions to the possibility of further eruptive activity at the summit crater. Authorities continue to monitor the volcano and issue advisories based on the evolving combination of gas emissions and eruptive behavior.

LEGAZPI CITY, Albay– The Philippine Institute of Volcanology and Seismology (Phivolcs) on Friday recorded a significant increase in sulfur dioxide (SO2) emissions at Mayon Volcano in Albay. In an advisory, Phivolcs said the volcanic SO2 flux on Thursday averaged 4,569 tonnes per day and increased to 7,475 tons per day on Friday, the highest emission from Mayon recorded in the last 16 years. The agency said the SO2 flux from the start of the eruption on Jan. 6 until present averages 2,300 tonnes per day. “Rising volcanic SO2 emissions likely forewarn of further eruptive activity at the summit crater and […]...Keep on reading: Phivolcs records increase in Mayon Volcano sulfur dioxide emissions
