Taal Volcano Advisory

24 March 2021, 12:30 PM

This is a notice of elevated increase in seismic activity
at Taal Volcano.

Alert Level 2 (Increased Unrest) is currently maintained over Taal Volcano, but is under constant evaluation.
This notice of elevated unrest is based on the following monitoring parameters:
- Shallow volcanic tremor episodes (2,015 since 13 February 2021) and a total of 734 low-frequency volcanic earthquakes
- High sulfur dioxide gas emission with peak at 1,184 tonnes/day on 21 March 2021
- Ongoing slight ground deformation of Taal Volcano Island (TVI) and Main Crater region

These parameters indicate that magma has been migrating across shallow depths beneath TVI, increasing the possibilities of magmatic eruption.
Entry into TVI, 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 must be strictly prohibited.
Local government units are advised to continuously assess and strengthen the preparedness of previously evacuated barangays around Taal Lake in case of renewed unrest.
DOST-PHIVOLCS is closely monitoring Taal Volcano’s activity and any new significant development will be immediately communicated to all stakeholders.
