MANILA, Philippines — The Philippine Institute of Volcanology and Seismology (Phivolcs) on Tuesday (June 15) recorded a total of 221 volcanic earthquakes in Taal Volcano in the past 24 hours.
According to their latest bulletin, Phivolcs recorded 29 low-frequency tremors out of the 221, while 192 volcanic tremors occurred with durations from one to 135 minutes.
There was also an upwelling of hot volcanic fluids which resulted in plumes reaching 1,500 meters tall, drifting southwest.
As of June 14, sulfur dioxide (SO2) emissions averaged 5,837 tonnes per day.
The agency previously warned residents near Taal Volcano, particularly in Agoncillo, Batangas, to wear face masks and to stay hydrated to prevent inhaling sulfur oxide.
Meanwhile, Phivolcs stated that due to the ground deformation parameters from electronic tilt, Taal Volcano Island has begun deflating in April 2021.
“The Taal region continues to undergo very slow extension since 2020. These parameters indicate overall that magmatic unrest continues to occur at shallow depths beneath the edifice,” the bulletin stated.
Alert Level 2 is still raised in the region where Phivolcs strongly recommends that entry must be strictly prohibited into Taal Volcano Island, Taal’s Permanent Danger Zone, or PDZ, especially the vicinities of the Main Crater and the Daang Kastila fissure, and occupancy and boating on Taal Lake. –AAC
