The alert warning in Taal Volcano has been downgraded to Alert Level 2 on Saturday morning, April 9 as the Philippine Institute of Volcanology and Seismology (Phivolcs) said unrest at the volcano “has markedly declined.”
“The rise in SO2 emissions prior to the March 26 phreatomagmatic eruption and its subsequent drop indicate that accumulated volcanic gas drives this type of eruptive activity at the main crater. Recent volcanic gas emissions, therefore, suggest that the potential for eruptive activity at present is low,” Phivolcs explained.
Three phreatomagmatic eruptions occurred in Taal Volcano on Thursday, Philippine Institute of Volcanology and Seismology (Phivolcs) Director Renato Solidum Jr. said.These occurred at 10:39 a.m. for two minutes; 10:47 a.m. and 10:55 a.m., both for one minute.Solidum told the Philippine… Read More
The Philippine Institute of Volcanology and Seismology (Phivolcs) on Tuesday said the likelihood of raising Taal Volcano’s alert status to level 4 is “not too high”. Phivolcs chief science research specialist Ma. Antonia Bornas said activity at the main crater of Taal was dominated by… Read More

PHIVOLCS BULLETIN MARCH 27
In the past 24-hour period, the Taal Volcano Network recorded three hundred two (302) volcanic earthquakes, including one hundred eighty-four (184) episodes of volcanic tremor having durations of one (1) to twelve (12) minutes, and one hundred eighteen (118) low frequency volcanic earthquakes. Activity at the Main Crater consisted of weak emission of steam-laden plumes from fumarolic vents that rose thirty (30) meters. Sulfur dioxide (SO2) emission that averaged 925 tonnes/day was measured yesterday, 26 March 2021. Temperature highs of 71.8°C and pH of 1.59 were last measured from the Main Crater Lake respectively on 04 March and 12 February 2021. Ground deformation parameters from electronic tilt, continuous GPS and InSAR data analysis indicated a very slow and steady inflation and expansion of the Taal region since after the January 2020 eruption. These parameters may indicate increased magmatic activity at shallow depths beneath the edifice.
The National Disaster Risk Reduction and Management Council (NDRRMC) and its counterpartsin local government units in the Calabarzon Region are closely monitoring the Taal Volcano unrest and have evacuated residents as stronger eruptions may occur.On Saturday morning, the Philippine… Read More
The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reminded the public on Saturday that the entire Taal Volcano Island has been declared as Permanent Danger Zone (PDZ) due to magmatic intrusion at the Main Crater that may further drive succeeding eruptions.
In view of this , DOST-PHIVOLCS is now raising the alert status of Taal from Alert Level 2 to Alert Level 3, said PHIVOLCS in its 3AM advisory on Saturday, March 26.
PHIVOLCS strongly recommended Taal Volcano Island and high-risk barangays of Bilibinwang and Banyaga, Agoncillo and Boso-boso, Gulod and eastern Bugaan East, Laurel, Batangas Province be evacuated due to the possible hazards of pyroclastic density currents and volcanic tsunami should stronger eruptions subsequently occur.
The public is reminded that the entire Taal Volcano Island is a Permanent Danger Zone (PDZ), and entry into the island as well as high-risk barangays of Agoncillo and Laurel must be prohibited, the agency said.
PHIVOLCS further advised that “all activities on Taal Lake should not be allowed at this time.”
Communities around the Taal Lake shores are advised to remain vigilant, take precautionary measures against possible airborne ash and vog and calmly prepare for possible evacuation should unrest intensify, PHIVOLCS added.
PHIVOLCS also said that civil aviation authorities must advise pilots to avoid flying over Taal Volcano Island as airborne ash and ballistic fragments from sudden explosions and pyroclastic density currents such as base surges may pose hazards to aircraft.
