Taal Volcano in Batangas had a series of minor eruptions on Sunday, Oct. 26, with one phreatic and two phreatomagmatic explosions recorded at its Main Crater, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
Phivolcs said the phreatic eruption occurred at 2:55 a.m., followed by phreatomagmatic events at 8:13 a.m. and 8:20 a.m.
The eruptions generated plumes that rose between 1,200 and 2,100 meters above the crater, based on data from the Main Crater IP and thermal cameras.
According to Phivolcs, a phreatic eruption occurs when water comes into contact with hot volcanic materials such as rocks or gases. No magma is involved in this type of eruption, which produces only a steam plume.
Meanwhile, a phreatomagmatic eruption happens when magma interacts with water, generating steam, ash, and occasionally fragmented volcanic materials.
Despite the activity, Alert Level 1 remains in effect over Taal Volcano, indicating "low-level unrest" with no sign of an imminent hazardous eruption.
However, Phivolcs warned that sudden phreatic or phreatomagmatic explosions, volcanic earthquakes, minor ashfall, and lethal accumulations of volcanic gases may still occur in the Main Crater.
The public is advised against entering Taal Volcano Island, particularly the main crater and the Daang Kastila fissure, due to the risk of sudden hazardous events.
Communities surrounding Taal Lake are also urged to remain vigilant.
