Steam-driven explosions, volcanic earthquakes and minor ashfalls possible over Taal Volcano
MANILA – Reports from the Philippine Institute of Volcanology and Seismology (PHIVOLCS) disclosed 98 earthquakes with durations from five to 12 minutes have been recorded over the past 24 hours which ended 8:00 A.M. today.
According to its Bulletin, the activity in the main crater included weak emission of white steam-laden plumes from fumaroles that rose to five metes high. Temperature reached 77.1 degrees Centigrade and pH of 1.59 were measured from the main crater last Saturday, February 12. It’s ground deformation parameters recorded a slight deflation around the main crater as of October 2020. However, overall, very slow and steady inflation of the Taal region was recorded by continuous GPS data after the eruption.
PHIVOLCS strongly recommends that entry to the Taal Volcano Island (TVI), Taal’s Permanent Danger Zone or PDZ, especially the vicinities of the Main Crater and the Daang Kastila fissure, must remain strictly prohibited.
Local government units have been advised to continuously assess the conditions of previously evacuated areas around Taal Lake for damages and road accessibilities and strengthen preparedness, contingency, and communication measures in case of another unrest episode. Civil aviation authorities should advise pilots to avoid flying close to the volcano because airborne ash and ballistic fragments from sudden explosions and ash carried by wind may pose hazards to the aircraft.
PHIVOLCS said they will continue to monitor the conditions in Taal as they do monitor other volcanos across the country.(Melo M. Acuna)
