MANILA, Philippines — The Philippine Institute of Volcanology and Seismology (Phivolcs) on Thursday said it recorded 35 volcanic earthquakes in the Taal Volcano over the past 24 hours.
In its latest advisory, Phivolcs said that 17 of the total tremors in Taal Volcano had durations of one to 59 minutes while 18 were low-frequency quakes.
Phivolcs is also monitoring a low-level background tremor in the area which has persisted since July 7.
Taal also generated high levels of volcanic sulfur dioxide (SO2) gas emissions and steam-rich plumes reaching 900 meters drifting east, according to Phivolcs, adding that SO2 emission averaged 5,286 tons.
Alert Level 3 remains hoisted over Taal, it also said. Alert Level 3 was raised on July 1 after the volcano had a phreatomagmatic blast, which means magma extruding from its main creater could trigger an “explosive eruption.”

Communities around Taal Lake are also advised to remain vigilant and calmly prepare for possible evacuation should unrest intensify.
“Phivolcs maintains its close monitoring of Taal Volcano and any new development will be communicated to all concerned stakeholders,” the agency said.
