LUCENA CITY — Taal Volcano in Batangas province continued its phreatic or steam-driven eruptions with three more events detected on Friday, September 27, the Philippine Institute of Volcanology and Seismology (Phivolcs) reported.
In its Saturday morning bulletin, the Phivolcs said the three eruptions on Friday, locally called “pusngat,” lasted two to eight minutes.
On Thursday, September 26, Taal Volcano logged three phreatic eruptions and another one on Wednesday, September 25.
Phivolcs defines a phreatic eruption as a “steam-driven explosion that occurs when water beneath the ground or on the surface is heated by magma, lava, hot rocks, or new volcanic deposits (for example, tephra and pyroclastic-flow deposits).”

State volcanologists also observed an “upwelling of hot volcanic fluids” in the main crater lake of the volcano, located on Taal Volcano Island, locally known as “Pulo,” which sits in the middle of Taal Lake.
No earthquake was recorded during this latest monitoring period.
Taal Volcano is still under alert level 1 (low level of volcanic unrest), Phivolcs said.
it also reminded the public that the volcano remained in an “abnormal condition” and “should not be interpreted to have ceased unrest nor ceased the threat of eruptive activity.”
