The Philippine Institute of Volcanology and Seismology (Phivolcs) reported that Taal Volcano in Batangas has continued to be active, with at least four volcanic earthquakes observed and 6,304 tons of sulfur dioxide emitted every day.
On Sunday, state volcanologists reported plumes at least 900 meters high flowing northeast from the volcano.
According to Phivolcs, there was also a noticeable swelling of hot volcanic fluids in the main crater lake.
The state meteorological agency also reported an inflation of western Taal and a long-term deflation of the Taal caldera.
Phivolcs warned of potential steam, phreatic, or gas-driven explosions.
Entry into Taal Volcano Island, particularly the main crater and Daang Kastila fissures, activities at Taal Lake, and flying any aircraft near the volcano are all prohibited, according to the statement.
Meanwhile, at least three volcanic earthquakes and 1,089 metric tons of sulfur dioxide per day were recorded at Negros Island's Kanlaon Volcano as Alert Level 1 remained in effect.
