The Philippines’ restive Taal Volcano logged two more minor phreatomagmatic eruptions overnight — at 11:41 pm on October 21 and 4:52 am on October 22 — sending steam-rich plumes up to 3,000 meters into the sky. The volcano remains at Alert Level 1, the lowest rung of the country’s five-step warning system.
According to the Philippine Institute of Volcanology and Seismology (PHIVOLCS), the back-to-back events were driven by magma meeting water beneath the crater, producing explosive bursts of steam, ash and rock fragments. The plumes drifted southwest, with no significant ashfall reported in nearby towns.
Plumes Tower 3,000 Meters
Phreatomagmatic eruptions occur when rising magma flashes groundwater into steam, and Taal has produced a string of them in recent weeks. Wednesday night’s double event was among the more vigorous, with tall, cauliflower-shaped plumes visible from lakeshore communities at dawn.
PHIVOLCS said volcanic earthquakes and ground deformation continue to be recorded, indicating magma movement beneath the edifice. Sulfur dioxide emissions remain elevated — a signature of Taal’s restless state — and the agency warned of possible vog, the hazy volcanic smog that can irritate eyes and lungs.
Alert Level 1 Holds
Despite the dramatic plumes, authorities kept the alert at Level 1, meaning abnormal activity short of an imminent eruption. Entry into Taal’s permanent danger zone — the Volcano Island itself — remains strictly prohibited, and lake communities have been told to stay vigilant.
Taal, one of the world’s smallest but most dangerous volcanoes, last erupted violently in January 2020, blanketing Luzon in ash and displacing hundreds of thousands. PHIVOLCS said it is watching the volcano around the clock and will raise the alert immediately if activity escalates.
Communities around Taal Lake — still scarred by the January 2020 eruption that displaced hundreds of thousands — watched the dawn plumes with familiar anxiety. Local disaster officials said evacuation plans are updated and ready, though none have been ordered. PHIVOLCS reiterated that Alert Level 1 means abnormal activity, not imminent eruption — but with Taal, residents know the line between the two can shift in hours.
