The Taal Volcano in Batangas generated a 900-meter plume on Monday morning after a minor phreatic eruption at 11:42 a.m., the Philippine Institute of Volcanology and Seismology (Phivolcs) has reported.
In a time-lapse footage released on its official social media accounts, Phivolcs captured smoke and steam rising from the summit of the volcano’s main crater.
Alert Level 1, indicating low-level unrest, prevails over Taal. This latest event follows after Phivolcs released separate advisories related to the activities of Bulusan and Kanlaon volcanoes on Sunday.
Mount Bulusan in Sorsogon registered a total of 72 volcanic earthquakes over the weekend associated with rock fracturing. It was also under Alert Level 1.
Mount Kanlaon in the Negros Island Region, meanwhile, had a 30-minute ash emission event. It was placed under Alert Level 2, signifying increased signs of unrest.
As these developed, the Civil Aviation Authority of the Philippines (CAAP) released fresh Notices to Airmen (NOTAMs) in light of the recent volcanic activity from Bulusan, Kanlaon, and Taal Volcanoes.
The agency advised pilots to avoid flying near these volcanoes.
NOTAM is a notice distributed by means of telecommunication containing information concerning the establishment, condition or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential to personnel concerned with flight operations.
In order to maintain aviation safety, the following NOTAMs have been issued:
- Bulusan Volcano: Effective from October 13, 2025, at 8:22 A.M. until October 14, 2025, at 9:00 AM, with vertical limits extending from the surface up to 10,000 feet.
- Kanlaon Volcano: Effective from October 13, 2025, at 8:15 AM until October 14, 2025, at 9:00 AM, with vertical limits extending from the surface up to 11,000 feet.
- Taal Volcano: Effective from October 13, 2025, at 8:17 AM until October 14, 2025, at 9:00 AM, with vertical limits extending from the surface up to 11,000 feet.
“All flight operators are strongly urged to refrain from flying near volcanic summits and to consistently monitor NOTAMs for any updates,” CAAP stated.
The agency assured it continues to be vigilant and proactive in ensuring flight safety in light of the ongoing volcanic activity throughout the country.
