Taal volcanic activity decreases

Taal Volcano has quieted down after a phreatomagmatic eruption that occurred in the evening of last Monday, 6 January.

Based on the 24-hour observation by the Philippine Institute of Volcanology and Seismology (Phivolcs), only one volcanic earthquake was recorded at Taal.

The acidity level of the main crater lake of the volcano was at 0.20 pH, indicating a concentrated acidity level in the lake.

There were no observed volcanic plumes. However, it continues to emit sulfur dioxide, as it logged 5,868 tons of sulfur dioxide (SO₂).

Despite the volcano being placed under Alert Level 1, Phivolcs reminded the public that phreatic or gas-driven explosions and expulsion of volcanic gas were still possible.

At Mt. Kanlaon volcano on Negros Island, where Alert Level 3 remains hoisted, an 800-meter volcanic plume was observed, which included a thick and continuous ash emission.

At least 2,000 tons of sulfur dioxide was emitted, which was accompanied by 15 volcanic earthquakes.

Earlier Friday, the local government of Negros Oriental declared a state of calamity following the volcanic eruption last 9 December.

In a statement, Joel Erestain, director of the Office of Civil Defense-Central Visayas and vice chairman of Task Force Kanlaon, said the declaration will help in the dissemination of needed resources, especially in Canlaon City and nearby areas.
