On 12 January around 21:00 UTC, the Philippine Institute of Volcanology and Seismology recorded increased volcanic activities generating an eruption plume one kilometre-high accompanied by volcanic tremor and felt earthquakes in Volcano Island and barangays of Agoncillo, in the province of Batangas. The government raised the alert status to Level 3 after the volcano spewed ash in a phreatic eruption. Residents from at least three municipalities of the province of Batangas were evacuated. The Ninoy Aquino International Airport (NAIA) in Manila put on hold all departing and arriving flights due to ash fall. (ECHO, 12 Jan 2020)
On 12 January, alert level-4 (hazardous eruption imminent) was raised over Taal Volcano located in the CALABARZON region 70 km south of the capital Manila. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) raised the alert level a few hours after it raised the alert to level-3 on the evening of 12 January. According to PHIVOLCS, Taal Volcano entered a period of unrest beginning with phreatic or steam-driven activity in several points inside the main crater that then progressed into a magmatic eruption at 2:49 a.m. local time on 13 January. This magmatic eruption is characterized by weak lava fountaining accompanied by thunder and flashes of lightning. Seismic activity was also recorded in Tagaytay City, Cabuyao, Laguna, Talisay, Alitagtag, Lemery and Bauan, Batangas, with over 75 volcanic earthquakes felt at an intensity ranging from II to V as of 5 a,m. that morning. These developments signify likely continuous magmatic intrusion beneath the volcano, which may lead to further eruptive activity. (OCHA, 13 Jan 2020)
As of 15 January, a total of 423 volcanic earthquakes were recorded in Taal region. Of which, 137 were felt, ranging from Magnitude 1.2 - 4.1 and Intensity of I - V. About 44,000 people have been affected, of which at least 40,000 are taking temporary shelter in 189 evacuation centers. If the eruption column remains at 3 km or below, the ash plumes will be drifted to the municipalities southwest of Taal Volcano. However, if a major eruption occurs and the column exceeds 3 km, ash plumes will be drifted over south-eastern portion of Batangas and some municipalities of Quezon, Mindoro, and Marinduque.
