Twenty-eight volcanic tremors and a 2,800-meter-high plume were recorded in Taal Volcano the past 24 hours, the Philippine Institute of Volcanology and Seismology (Phivolcs) said on Wednesday, Aug. 17, as the restive volcano remained under Alert Level 1.
In its 8 a.m. bulletin, Phivolcs said the volcanic tremors lasted four to 12 minutes.
Meanwhile, the 2,800-meter tall “voluminous” plume of steam had drifted north and northeast.
Phivolcs said that Taal’s volcanic sulfur dioxide averaged 4,312 tons per day, as of Aug. 16.
Taal Volcano remains under Alert Level 1, which means it is still in an abnormal condition and should not be interpreted to have ceased unrest nor ceased the threat of eruptive activity.
Under Alert Level 1, sudden steam-driven or phreatic explosions, volcanic earthquakes, minor ashfall and lethal accumulations or expulsions of volcanic gas can occur and threaten areas within the Taal Volcano Island (TVI).
“Phivolcs strongly recommends that entry into TVI, Taal’s permanent danger zone or PDZ, especially the vicinities of the main crater and the Daang Kastila fissure, must remain strictly prohibited,” it said.
