Taal Volcano’s sulfur dioxide emission declines
MANILA, Philippines — The emission of sulfur dioxide from the main crater of the Taal Volcano has weakened, the Philippine Institute of Volcanology and Seismology (Phivolcs) said Wednesday.
In its 8 a.m. bulletin, Phivolcs said that the sulfur dioxide emitted from Taal Volcano was measured at an average of 55 tons per day on Tuesday, February 4, a significant drop from the 231 tons the day before.

Phivolcs added that volcano’s activity was characterized by “weak” emission of steam, reaching 50 to 100 meters tall that drifted southwest.
The Taal Volcano Network, which Phivolcs said records “small but undetectable” earthquakes, recorded 156 volcanic earthquakes including two low-frequency events and 18 harmonic tremors having durations of one to three minutes.
Alert Level 3 remains raised over Taal Volcano, meaning that “sudden steam-driven and even weak phreatomagmatic explosions, volcanic earthquakes, ashfall, and lethal volcanic gas expulsions can still occur and threaten areas within Taal Volcano Island and nearby lake shores.”
