The Philippine Institute of Volcanology and Seismology (Phivolcs) observed “increased” and “continuous” degassing activity from Taal Volcano on Thursday, Oct. 12.

In a 6 p.m. advisory, Phivolcs said volcanic sulfur dioxide (SO2) emissions from Taal’s main crater had increased to 9,762 tons per day on Thursday, up from 2,887 tons per day on Oct. 6.

“This is the highest recorded SO2 emission from Taal for the year,” it pointed out.

Meanwhile, Phivolcs said no volcanic smog or “vog” over Taal Caldera was monitored as of Thursday.

Citing the Philippine Atmospheric, Geophysical and Astronomical Services Administration’s (PAGASA) forecast, Phivolcs said wind speeds over the Taal region will significantly decrease in the coming weekend.

However, PAGASA noted that if the “elevated” SO2 degassing continues, there will also be a likelihood for volcanic SO2 to accumulate and generate vog.

Phivolcs reminded the public that the composition of volcanic gases can cause irritation of the eyes, throat, and respiratory tract, which may be severe depending on the gas concentrations and durations of exposure.

It advised people living near Taal Volcano to avoid outdoor activities, wear N95 face masks, and drink enough amount of water. (Lizst Torres Abello)
