BATANGAS — Taal Volcano produced a minor phreatomagmatic eruption at its Main Crater at 2:34 p.m. on Tuesday, June 30, 2026, marking the second such event recorded at the volcano in a single day, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said.
The eruption lasted about four and a half minutes and consisted of three pulses, based on seismic, infrasound, and visual observations. The event sent jets of dark gray ash and steam-rich plumes rising 1,200 meters above the crater before drifting southwest.
The 2:34 p.m. event came hours after an earlier minor phreatomagmatic eruption at the same crater, which occurred from 7:13 a.m. to 7:17 a.m. That morning eruption generated a plume reaching about 450 meters above the crater, captured by the volcano's IP surveillance camera.
PHIVOLCS classified Tuesday's morning activity as the fourth eruptive event recorded at Taal this month, following similar phreatomagmatic eruptions on June 4, June 5, and June 6.
In its bulletin for the period, PHIVOLCS recorded that Taal emitted 881 metric tons of sulfur dioxide over the preceding 24 hours.
Alert Level 1 remained in effect over Taal following the afternoon eruption. PHIVOLCS stressed, however, that Alert Level 1 still represents an abnormal condition and should not be taken to mean that volcanic unrest has ended or that the possibility of a larger eruption has passed.
The agency warned that sudden steam-driven or minor phreatomagmatic eruptions, minor ashfall, and potentially lethal accumulations or expulsions of volcanic gases may still occur within Taal Volcano Island.
The entire Taal Volcano Island remains a Permanent Danger Zone. Entry into the island — particularly the Main Crater and the Daang Kastila fissure area — is strictly prohibited. Pilots are also advised to avoid flying close to the volcano.
The public is advised to stay alert and to follow advisories issued only through official DOST-PHIVOLCS channels.
