MANILA, Philippines—The Philippine Institute of Volcanology and Seismology (Phivolcs) has recorded five short phreatomagmatic bursts at Taal Volcano.
In the latest bulletin, as of July 8, sixty (60) volcanic earthquakes, including five explosion-type earthquakes, and twenty-four low frequency volcanic earthquakes occurred at Taal Volcano.
Phivolcs also recorded 24 low frequency volcanic earthquakes, 21 volcanic tremor events having durations of two to four minutes, 10 hybrid earthquakes, and low-level background tremor that ended on Wednesday (July 8).
High levels of volcanic sulfur dioxide (SO2) gas emissions, that averaged 11,397 tonnes/day on 07 July 2021, and steam-rich plumes were also recorded. The steam-rich plumes rose 1,500 meters before drifting southwest from the Taal main crater.
Alert Level 3 prevails over Taal Volcano. The public is reminded that the entire Taal Volcano Island is a Permanent Danger Zone (PDZ), and entry into the island as well as into the high-risk barangays of Agoncillo and Laurel must be prohibited due to the hazards of pyroclastic density currents and volcanic tsunami should strong eruptions occur.
“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,” according to Phivolcs.
Meanwhile, Phivolcs also urged the civil aviation authorities to advise pilots not to fly 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. AAC
