According to the latest PHIVOLCS newsletter, Taal Volcano remains under Alert Level 4 on Monday amid the ongoing “period of intense unrest.”
The PHIVOLCS said the initial phreatic or steam-driven activity that started on Sunday was evolving into a magmatic eruption at 2:49 a.m. At 4:28 hrs.
The magmatic eruption is characterized by a small lava fountain with thunder and lightning flashes.
“Thirty-two of these earthquakes were felt in Tagaytay City, Cabuyao, Laguna, Talisay, Alitagtag, Lemery and Bauan, Batangas, with intensities ranging from Intensity II–V,” the PHIVOLCS said.
“Such strong seismic activity is likely to mean continuous magmatic intrusion under the Taal site, which could contribute to further eruptive activity.”
The total evacuation of those on the island of the volcano has been reiterated.
Those from Taal Main Crater within the 14-kilometer radius have also been advised to evacuate due to high risks of pyroclastic density currents and volcanic tsunami.
Meanwhile, residents in the general north of Taal volcano have been advised to take precautionary action for the effects of heavy and prolonged ashfalls.
While airborne ash and ballistic fragments from the eruption column pose risks, the PHIVOLCS said, the airspace around Taal Volcano must be avoided by aircraft.
According to the National Disaster Risk Reduction and Management Council, more than 7,000 have already been evacuated because of the activities of Taal Volcano.
