The Philippine Institute of Volcanology and Seismology (Phivolcs) on Monday, Oct. 9, observed the upwelling of hot volcanic fluids at the Main Crater Lake and sulfur dioxide emission (SO2) of 2,887 tons a day causing the formation of vog around Taal Volcano.

There is a "voluminous" emission of plume drifting west and southwest at 2,400 meters, Phivolcs said.
Phivolcs warned the public to avoid exposure to the areas where the volcanic gases come from.
People in affected areas were advised to stay at home, close windows and doors, wear N95 face masks, drink more water, and see a doctor, if necessary, to observe the effects of the volcanic smog.
Meanwhile, there is no seismic activity being monitored by Phivolcs at Taal Volcano, as it remained under Alert Level 1. (Lizst Torres Abello)
