Taal Volcano remains 'unstable', generates more quakes in past 24 hours

Published May 20, 2021 09:06 am

The Philippine Institute of Volcanology and Seismology (Phivolcs) said Taal Volcano in Batangas remains “unstable” as more earthquakes have been detected within its vicinity in the past 24 hours.

Based on the latest volcano bulletin issued Thursday, May 20, Phivolcs recorded 169 volcanic earthquakes in Taal Volcano within the past 24-hour monitoring period.

Of the number, 30 were low frequency volcanic earthquakes and 139 were volcanic tremor events with durations between two to 20 minutes, and a low-level background tremor that has persisted since April 8.

Moreover, Phivolcs observed an upwelling of hot volcanic fluids at Taal’s main crater lake which generated 300-meter tall moderate plumes that drifted to the southwest.

Sulfur dioxide emission that averaged 3,611 tonnes/day was registered on May 19.

Phivolcs said Alert Level 2 or “Increased Unrest” has been maintained over Taal Volcano, noting that “elevated unrest has been recurring and volcano conditions remain unstable.”

Phreatic explosions, volcanic earthquakes, minor ashfall, and lethal accumulations or expulsions of volcanic gas can occur under such conditions.

Phivolcs has urged the public not to enter into Taal Volcano island, Taal’s permanent danger zone, especially the vicinities of the Main Crater and the Daang Kastila fissure.

The agency has also advised against occupancy and boating on Taal Lake.
