The Philippine Institute of Volcanology and Seismology is not yet ruling out a possible “eruptive activity” at the main crater of Taal Volcano.
In an 8 a.m. bulletin on Sunday, the agency said the activity in the main crater was still characterized by the moderate emission of white to dirty-white steam-laden plumes rising 200 meters to 300 meters before drifting southwest.
There was also an “ongoing” weak steaming from fissure vents along the Daang Kastila trail rising 10 meters to 20 meters high.
Moreover, the sulfur dioxide emission had an average of 116 tons on Feb. 8.
The Taal Volcano Network recorded 115 volcanic earthquakes, including two low-frequency events and five harmonic tremors having durations of one minute to four minutes.
“These earthquakes signify magmatic activity beneath the Taal edifice that could lead to eruptive activity at the main crater,” the bulletin says.
PHIVOLCS maintained its Alert Level 3 over the volcano.
