Two phreatic eruption events were reported in Taal Volcano on Sunday, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said Monday.
In its bulletin, PHIVOLCS said the phreatic eruptions lasted three to 13 minutes.
Phreatic eruptions are steam-driven explosions that occur when water beneath the ground or on the surface is heated by magma, lava, hot rocks, or new volcanic deposits, PHIVOLCS said.
A weak emission of plumes of up to 600 meters tall were observed from the volcano, which drifted to the west-southwest direction.
Taal Volcano emitted 1,256 tons of sulfur dioxide gas on Saturday and its Main Crater Lake had an upwelling of hot volcanic fluids.
A long-term deflation of the Taal Caldera and a short-term inflation of the general northern and southeastern flanks of the Taal Volcano Island were also observed.
No volcanic earthquakes were recorded in the volcano, PHIVOLCS said.
Alert Level 1 is maintained over Taal Volcano, which means the volcano is in abnormal condition and should not be interpreted to have ceased unrest nor ceased the threat of eruptive activity.
The possible hazards under Alert Level 1 are sudden steam-driven or phreatic explosions, volcanic earthquakes, minor ashfall and lethal accumulations or expulsions of volcanic gas.
People are prohibited from entering the Taal Volcano Island, permanent danger zone or PDZ, especially the vicinity of the Main Crater and the Daang Kastila fissure.
Flying close to the volcano is also prohibited. —Joviland Rita/KBK, GMA Integrated News
