MANILA, Philippines — At least 69 volcanic tremors were recorded around Taal Volcano in the past 24 hours, according to the Philippine Institute for Volcanology and Seismology.
Phivolcs said the quakes lasted for one to 61 minutes each.
Weak steam-laden plumes were observed at the vents of the main crater during these volcanic quakes.
The highest number of tremors recorded in a day since the volcano showed signs of activity again was on Feb. 18 at 91.
Taal Volcano remains under Alert Level 1, which means sudden steam-driven or phreatic explosions, volcanic earthquakes, minor ashfall and expulsion of volcanic gas could occur and threaten areas within Taal Volcano Island.
Entry to the island, which is a permanent danger zone, is strictly prohibited.
The National Disaster Risk Reduction and Management Council advised local government units to continuously assess the preparedness of residents of barangays around Taal Lake.
Phivolcs Director Renato Solidum said there is an increasing likelihood of a phreatic eruption but it would be limited to Volcano Island.
