TAAL VOLCANO ADVISORY
12 April 2024
9:00 AM
This is a notice of a phreatic eruption in Taal Volcano.
A phreatic or steam-driven eruption at the Taal Main Crater occurred in the early morning between 5:11 AM to 5:24 AM based on seismic, visual and infrasound records of the Taal Volcano Network (TVN). The event produced a white steam-laden plume 2400 meters tall that drifted southwest based on IP camera images. Sulfur dioxide (SO2) emission averaged 9,677 tonnes/day yesterday, 11 April 2024, and has been consistently elevated this year, averaging 10,248 tonnes/day since January 2024. The phreatic event was likely driven by the continued emission of hot volcanic gases at the Taal Main Crater and could be succeeded by similar phreatic activity. The background levels of volcanic earthquake activity and ground deformation detected at Taal indicate that unrest is unlikely to progress into magmatic eruption.
DOST-PHIVOLCS reminds the public that Alert Level 1 prevails over Taal Volcano, which means that it is still in abnormal condition and should not be interpreted to have ceased unrest nor ceased the threat of eruptive activity. At Alert Level 1, sudden steam-driven or phreatic explosions, volcanic earthquakes, minor ashfall and lethal accumulations or expulsions of volcanic gas can occur and threaten areas within TVI. Furthermore, degassing of high concentrations of volcanic SO2 continues to pose the threat of potential long-term health impacts to communities around Taal Caldera that are frequently exposed to volcanic gas. DOST-PHIVOLCS strongly recommends that entry into TVI, Taal’s Permanent Danger Zone or PDZ, especially the vicinities of the Main Crater and the Daang Kastila fissure, must remain strictly prohibited. Local government units are advised to continuously monitor and assess preparedness of their communities and undertake appropriate response measures to mitigate hazards that could be posed by long-term degassing and related phreatic activity. 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 aircrafts.
DOST-PHIVOLCS is closely monitoring Taal Volcano’s activity and any new significant development will be immediately communicated to all stakeholders.
