The Philippine Institute of Volcanology and Seismology (Phivolcs) continues to detect “increased unrest” at Taal Volcano, based on the 24-hour monitoring of the active volcano in Batangas.

In the past 24 hours, Phivolcs on Tuesday, Aug. 31, said Taal registered 52 earthquakes, including 23 tremor events that lasted one to five minutes, low-frequency volcanic earthquakes, and low-level background tremor that has persisted since July 7, 2021.

Moreover, the activity at Taal’s main crater was still dominated by the upwelling of hot volcanic fluids in its lake which generated a 2,000-meter-high plume.

Sulfur dioxide (SO2) emission averaged 3,848 tonnes per day last Aug. 25, Phivolcs said.

Taal Volcano remains under Alert Level 2, which means that 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 the volcano island.

Phivolcs reminded the public that entry into the Taal Volcano Island, especially the vicinities of the main crater and the Daang Kastila fissure, is strictly prohibited.

Boating on Taal Lake must also be prohibited, it added.
