The Philippine Institute of Volcanology and Seismology (Phivolcs) has recorded multiple volcanic earthquakes within the vicinity of Taal Volcano over the last few days. Alert Level 1 remains raised in the area.
11 volcanic earthquakes were recorded in the last 24 hours. They are “associated mainly with rock-fracturing processes beneath and around the edifice,” according to Phivolcs’ May 20 bulletin.
“Weak steaming or fumarolic activity rising 100 meters high before drifting southwest was observed from vents on the Main Crater and fissure vents along the Daang Kastila Trail,” it stated.
Phivolcs’ bulletin for the Taal Volcano at 8 a.m. on May 19 stated 15 volcanic earthquakes were recorded in the area while the May 18 bulletin showed 11 volcanic earthquakes reported by the Taal Volcano Network.
A total of 13 volcanic earthquakes were reported by Phivolcs on May 17, 11 on May 16, and 2 on May 15.
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).
“Local government units are advised to continuously assess previously evacuated barangays around Taal Lake for damages and road accessibilities and to strengthen preparedness, contingency, and communication measures in case of renewed unrest,” said Phivolcs.
The public was asked to observe precautions due to ground displacement across fissures, possible ashfall, and minor earthquakes.
