3 min read

 Philippines Philippines – The Philippine Institute of Volcanology and Seismology on Saturday lowered the alert level of Taal Volcano in Batangas from Alert Level 3 (magmatic unrest) to Alert Level 2 (decreased unrest).

“Following the phreatomagmatic eruption of the Main Crater on 26 March 2022 and six (6) weak phreatomagmatic bursts until 31 March 2022, unrest at Taal Volcano has markedly declined,” PHIVOLCS said.

“Activity in the past two weeks has been characterized by a significant drop in volcanic degassing from the Main Crater and in the incidence of volcanic earthquakes,” it added.

PHIVOLCS said only 86 volcanic earthquakes that are of small magnitude and are imperceptible have been recorded since March 26.

“These consist of 26 volcanic tremors, 59 low-frequency volcanic earthquakes and 1 volcano-tectonic event, most of which occurred 0-7 kilometers beneath the Main Crater and the eastern sector of Taal Volcano Island or TVI,” it added.

PHIVOLCS said most of the earthquakes were due to “volcanic degassing from the shallow magma and hydrothermal region beneath the TVI edifice.”

It added that “background tremor associated with shallow hydrothermal activity ceased on 31 March.”

“There has been no recorded seismic activity related to new magmatic intrusions from Taal’s deeper magma source since unrest began last year,” the department said.
