The Philippine Institute of Volcanology and Seismology (Philvolcs) has maintained the Alert Level 2 Status over the Taal volcano after recording at least 174 volcanic earthquakes from the volcano on Wednesday.

“This includes 120 episodes of volcanic tremor having durations of one to 19 minutes, 53 low-frequency volcanic earthquakes, one hybrid earthquake, and low-level background tremor that started at 9:05 AM on 08 April 2021.” according to its bulletin.

On Thursday, Philvolcs said the activity at Taal’s main crater also consisted of weak emission of steam-laden plumes that rose to five meters.

The Taal volcano network also observed significant sulfur dioxide emission averaging 1,886 tonnes per day on April 12, 2021.

It also observed a “very slow and steady” inflation and expansion of the Taal Region that began after the January 2020 eruption

Phivolcs said that Alert Level 2 or “Increased Unrest” remains hoisted over Taal Volcano as phreatic explosions, volcanic earthquakes, minor ashfall, and lethal accumulations or expulsions of volcanic gas can occur.

local Government Units are advised to stay cautious and strengthen preparedness in case of renewed unrest.

The agency has recommended prohibiting the entry in the Taal’s permanent danger zone, especially the vicinities of the main crater and Daang Kastilla Fissure.
