LUCENA CITY — Sulfur dioxide emissions from Taal Volcano have dropped substantially after a period of heightened gas release, according to data released Thursday by the Philippine Institute of Volcanology and Seismology (Phivolcs).

Measurements over the past 24 hours showed the volcano's main crater discharged 223 metric tons of sulfur dioxide, marking a reversal from the elevated levels recorded in preceding days. The associated gas plume reached an altitude of 750 meters above the volcano's summit.

The decline in emissions provides some relief to communities surrounding the volcano, which is located in Batangas province and remains one of the country's most closely monitored volcanic features. Phivolcs continues to observe Taal's activity levels as part of its regular monitoring program.

Residents and local officials in nearby provinces have been advised to remain alert to any changes in volcanic behavior. The agency maintains its alert status for the volcano and urges the public to follow guidance from local government units regarding safety precautions.
