MANILA, Philippines — A minor phreatic eruption occurred at Taal Volcano in Batangas province, the Philippine Institute of Volcanology and Seismology (Phivolcs) said on Monday.
Phivolcs told INQUIRER.net that the minor eruption, which lasted for a minute, was observed on Sunday, from 11:23 p.m. to 11:24 p.m.
A phreatic eruption is 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),” according to Phivolcs in a Facebook post.
Phivolcs also said that the volcano emitted 2,068 tons of sulfur dioxide with the upwelling of hot volcanic fluids in the lake. The emission of flumes rose 900 meters high, spreading toward the southwest
