Taal Volcano at Alert level 2 and Volcanic Smog reached Manila area

     Manila - The Taal Volcano Network recorded six (6) volcanic earthquakes and low-level background tremor that has persisted since 08 April 2021 for the past 24 hours. High levels of volcanic sulfur dioxide or SO2 gas emissions and steam-rich plumes that rose as much as two thousand five hundred (2,500) meters high have been observed from the Taal Main Crater. Sulfur dioxide (SO2) emission averaged 8,982 tonnes/day on 29 June 2021. Based on ground deformation parameters from electronic tilt, continuous GPS and InSAR monitoring, Taal Volcano Island has begun deflating in April 2021 while the Taal region continues to undergo very slow extension since 2020. These parameters indicate overall that magmatic unrest continues to occur at shallow depths beneath the edifice. The volcanic smog is the mixture of smoke from the volcano and fog also called haze.

Alert Level 2 (Increased Unrest) is currently maintained over Taal Volcano. DOST-PHIVOLCS reminds the public that at Alert Level 2, sudden steam- or gas-driven explosions, volcanic earthquakes, minor ashfall, and lethal accumulations or expulsions of volcanic gas can occur and threaten areas within and around TVI. DOST-PHIVOLCS strongly recommends that entry must be strictly prohibited into Taal Volcano Island, Taal’s Permanent Danger Zone or PDZ, especially the vicinities of the Main Crater and the Daang Kastila fissure, and occupancy and boating on Taal Lake. Local government officials are advised to continuously assess and strengthen the preparedness of previously evacuated barangays around Taal Lake in case of renewed unrest. Civil aviation authorities must advise pilots to avoid flying close to the volcano as airborne ash and ballistic fragments from sudden explosions and wind-remobilized ash may pose hazards to aircraft. DOST-PHIVOLCS is closely monitoring Taal Volcano’s activity and any new significant development will be immediately communicated to all stakeholders. Wear Gas mask or N95 mask to protect yourselves from harmful sulfuric gas.
