Of the number, a lone volcanic tremor event having duration of two minutes and four low-frequency volcanic quakes were recorded, as well as low-level background tremor that has persisted since July, Phivolcs said.

In its latest volcano bulletin, the agency said that the activity at Taal’s main crater was dominated by upwelling of hot volcanic fluids in its lake which generated plumes reaching up to 3,000 meters high that drifted towards south-southwest and southwest.

It also added that the volcano’s sulfur dioxide emission averaged 10,772 tonnes on Nov. 17.

With this observations, the Phivolcs reiterated that Alert Level 2 remains hoisted over Taal Volcano.

Under this alert level, sudden steam or gas-driven explosions, volcanic earthquakes, minor ashfall, as well as lethal expulsions of volcanic gas may occur and threaten the areas within the Taal Volcano Island.

“DOST-PHIVOLCS strongly recommends that entry into Taal Volcano Island and Taal’s Danger Zone or PDZ must be strictly prohibited, especially the vicinities of the Main Crater and the Daang Kastila fissure,” it said, adding that occupancy and boating on Taal Lake is not allowed.

Officials of the local government are also advised to continuously assess and strengthen the preparedness of previously evacuated barangays around the Taal Lake in case a renewed unrest takes place. (Charie Mae F. Abarca)
