MT. TAAL ACTIVITY UPDATE:
Activity in the Main Crater in the past 24 hours has been characterized by weak to moderate emission of white steam-laden plumes 100 to 800 meters high from the Main Crater that drifted southwest. Sulfur dioxide (SO2) emission was measured at an average of 409 tonnes/day.
VOLCANIC EARTHQUAKE UPDATE:
TThe Philippine Seismic Network (PSN) plotted a total of seven hundred forty-four (744) volcanic earthquakes since 1:00 PM, January 12, 2020. One hundred seventy-six (176) of these registered at magnitudes M1.2-M4.1 and were felt at Intensities I-V. Since 5:00 AM on January 24, 2020 until 5:00 AM today, there were six (6) volcanic earthquakes plotted that registered at magnitudes M1.5-M2.3 with no felt event.
For the past 24 hours, the Taal Volcano Network, which can record small earthquakes undetectable by the PSN, recorded four hundred twenty (420) volcanic earthquakes including eleven (11) low-frequency earthquakes. Seismic activity likely signifies magmatic intrusion beneath the Taal edifice that may lead to eruptive activity.
WARNING UPDATE:
Alert Level 4 still remains in effect over Taal Volcano. DOST-PHIVOLCS recommends 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. Based on PAGASA wind forecast, if the eruption plume remains below five (5) km, ash will be drifted to the municipalities west and northwest of the Main Crater; however, if a major eruption occurs during the day and the eruption column exceeds 7 km, ash will also be drifted over the western parts of Laguna and Quezon provinces. Residents around the 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.
