Alert Level 4 still remains in effect over Taal Volcano. This means that hazardous explosive eruption is possible within hours to days. A total of four hundred sixty-seven (467) volcanic earthquakes including eight (8) low-frequency earthquakes in the last 24 hours suggest continuous magmatic intrusion beneath the Taal edifice, which may lead to further eruptive activity.
TAAL VOLCANO BULLETIN 23 January 2020 8:00 A.M.
Activity in the Main Crater in the past 24 hours has been characterized by weak to moderate emission of white steam-laden plumes 50 to 500 meters high from the Main Crater that drifted southwest. Sulfur dioxide (SO2) emission was measured at an average of 141 tonnes/day. The Philippine Seismic Network (PSN) plotted a total of seven hundred thirty-one (731) 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 22, 2020, until 5:00 AM today, there were six (6) volcanic earthquakes plotted that registered at magnitudes M1.5-M3.4 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 sixty-seven (467) volcanic earthquakes including eight (8) low-frequency earthquakes.
Such intense activity likely 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. 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 some 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. PHIVOLCS
