The Taal Volcano spewed weak steam-laden plumes from its main crater and produced weak explosions Thursday, according to the latest update on its eruption issued by the Philippine Institute of Volcanology at 5 p.m.
The plumes went 800 meters high into the air and drifted to the southwest.
“No additional fissures were mapped and reported. Existing ones are in the identified barangays of Lemery, Agoncillo, Talisay, and San Nicolas in Batangas Province as indicated in the January 15, 2020 5:00 PM update. Receding of Taal Lake water has been observed in Talisay, Laurel, Alitagtag and Lemery in Batangas Province,” the Phivolcs update read.
Meanwhile, the Philippine Seismic Network plotted a total of 595 volcanic earthquakes since 1 p.m., 12 January 2020.
A total 176 of these were felt with intensities ranging from I to V.
“Since 5:00 AM to 3:00 PM today, there were thirty (30) volcanic earthquakes plotted, including one (1) earthquake which was felt at Intensity I. This signifies continuous magmatic intrusion beneath the Taal edifice, which may lead to further eruptive activity,” the update read.
Phivolcs said the volcano’s Alert Level remains at 4 which means that hazardous explosive eruption is possible within hours to days.
The agency strongly reiterated the total evacuation of Taal Volcano Island and high-risk areas as identified in the hazard maps within the 14-kilometer radius from the Taal main crater and along the Pansipit River Valley where fissuring has been observed.
Residents around Taal Volcano are advised to guard against the effects of heavy and prolonged ashfall, the Phivolcs added.
Civil aviation authorities must advise pilots to avoid the airspace around Taal Volcano as airborne ash and ballistic fragments from the eruption column pose hazards to aircraft.
