A minor phreatomagmatic eruption occurred at Taal Volcano in Batangas early Monday morning, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported.
In a Facebook post, PHIVOLCS said the eruption happened from 6:13 a.m. to 6:14 a.m., generating plumes that rose about 500 meters above the main crater.
The agency explained that phreatomagmatic eruptions occur when magma interacts with water, often resulting in multiple explosive events.
PHIVOLCS said Alert Level 1 remains in effect, indicating the volcano is in an abnormal condition and that unrest or eruptive activity has not fully ceased.
Under this alert level, possible hazards include sudden steam-driven explosions, volcanic earthquakes, minor ashfall, and dangerous accumulations of volcanic gas.
PHIVOLCS continues to prohibit entry into Taal Volcano Island, the Permanent Danger Zone, and the areas near the Main Crater and Daang Kastila fissure. Flying close to the volcano is also strictly prohibited.
