Taal volcano records 152 volcanic earthquakes, ‘short-lived’ phreatomagmatic explosion

MANILA, Philippines – The Philippine Institute of Volcanology and Seismology (Phivolcs) recorded 152 volcanic earthquakes and a brief phreatomagmatic explosion (water and magma interact to produce an eruption) at Taal Volcano during a 24 hour monitoring period.

Phivolcs said Thursday the 152 quakes include 33 volcanic tremor events lasting one to two minutes, 114 low-frequency volcanic quakes, five hybrid events and a low-level background tremor that has persisted for July 7, 2021.

“A short-lived phreatomagmatic burst was recorded at 3:55 p.m. yesterday that lasted 2 minutes based on the seismic record. This event produced a 300-meter-high plume that drifted southwest,” said Phivolcs in its volcanic bulletin published at 8 am.

An upwelling of hot volcanic fluids in the volcano’s lake generated 900-meter-high plumes that drifted south-southwest-dominated activity at the volcano’s main crater, the agency said.

Sulfur dioxide emissions averaged 7,902 tonnes per day on Wednesday, Phivolcs said.

“Based on ground deformation parameters from electronic tilt, continuous GPS and InSAR monitoring, Taal Volcano Island and the Taal area began to deflate in October 2021,” he said. he adds.

Alert Level 2, which signifies increased unrest, is still high at Taal Volcano. Below this alert level, sudden steam or gas explosions, volcanic earthquakes, minor ashfall, and deadly accumulations or expulsions of volcanic gas may occur and threaten areas in and around from Taal Volcano Island, according to Phivolcs.
