Taal Volcano’s eruption has been characterized by continuous magmatic and hydrovolcanic activity that generated 700-meter tall dark gray steam-laden plumes that drifted to the general southwest.

In addition to the previously identified fissures in Lemery (Sinisian, Mahabang Dahilig, Dayapan, Palanas, Sangalang, Poblacion, Mataas na Bayan), Agoncillo (Pansipit, Bilibinwang), Talisay (Poblacion 1, Poblacion 2, Poblacion 3, Poblacion 5) and San Nicolas (Poblacion), new fissures were observed in Sambal Ibaba, Lemery. Drying up of portions of Pansipit River has also been observed. Furthermore, newly acquired satellite images would show that the Main Crater Lake (MCL) has been drained and new vent craters have been formed inside the Main Crater and on the north flank of the volcano.   

The Philippine Seismic Network plotted a total of five hundred twenty (520) volcanic earthquakes since 1:00 PM, January 12, 2020. One hundred sixty-nine (169) of these were felt with intensities ranging from Intensity I – V. Since 5:00 AM to 4:00 PM today, there were fifty-three (53) volcanic earthquakes plotted and twelve (12) of which were felt with intensities ranging from Intensity I – III. Such intense seismic activity probably signifies continuous magmatic intrusion beneath the Taal edifice, which may lead to further eruptive activity.

Alert Level 4 still remains in effect over Taal Volcano. This means that hazardous explosive eruption is possible within hours to days. DOST-PHIVOLCS strongly reiterates total evacuation of Taal Volcano Island and high-risk areas as identified in the hazard maps within the 14-km radius from 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. 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. DOST-PHIVOLCS is continually monitoring the eruption and will update all stakeholders of further developments.
