Taal Volcano’s main crater had a “very weak emission” of steam-laden plumes that rose five meters in the past 24 hours, Phivolcs said Sunday.
It also recorded 216 volcanic earthquakes with 177 volcanic tremors lasting up to 32 minutes, state seismologists said in their 8 a.m. Taal Volcano bulletin.
The volcano remains under alert level 2, the second-lowest in a 5-step system that warns of probable magmatic activity that may or may not lead to an eruption.
Phivolcs said the entry into the Taal Volcano Island, Taal’s permanent danger zone, especially the vicinity of the main crater and the Daang Kastila fissure, and occupancy and boating on Taal Lake remained strictly prohibited.
The people in the towns surrounding the lake have been advised to continuously assess and strengthen their preparedness in case of renewed unrest.
The volcano, which sits on an island surrounded by a lake in Batangas province, had a steam-driven eruption on Jan. 12, 2020, triggering an ash fall that reached parts of Metro Manila and nearby provinces.
The eruption displaced more than 700,000 people in Central Luzon, Calabarzon and Metro Manila.
The damage to infrastructure and agriculture in Batangas, Cavite and Laguna was pegged at P3.4 billion.
