Taal Volcano posts phreatic eruption again, says Phivolcs
MANILA, Philippines — Taal Volcano registered a phreatic eruption before noon Friday, the Philippine Institute of Volcanology and Seismology (Phivolcs) reported.
Phivolcs told that the minor explosion, which lasted for three minutes, was recorded from 11:51 a.m. to 11:54 a.m. on January 10.
The state volcanologist, however, said it did not monitor any vog from the volcano’s crater.
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.

Long-term deflation of the volcano’s caldera and short-term inflation of the general northern and southeastern parts of the volcano island were also observed on Friday, Phivolcs noted.
Alert Level 1 is still raised over the volcano and Phivolcs repeated its warning that entering Taal Volcano Island and flying any aircraft close to the volcano premises is prohibited.
Phivolcs likewise reiterated that stream-driven or phreatic explosions, volcanic earthquakes, minor ashfall, and explosions of volcanic gas are still imminent.
