Alert Level 2 is maintained over Taal Volcano, the Philippine Institute of Volcanology and Seismology (Phivolcs) said Sunday.
In its 8 a.m. bulletin, Phivolcs reported weak emission of steam-laden plumes rising 50 to 100 meters high before drifting northeast.
State volcanologists also recorded 22 volcanic earthquakes that are associated with rock fracturing processes beneath and around the volcano.
The earthquakes included one low frequency event associated with magmatic fluids.
“At Alert Level 2, sudden steam-driven or phreatic explosions, volcanic earthquakes, ashfall and lethal accumulations or expulsions of volcanic gas can occur and threaten areas within Taal Volcano Island (TVI) and along its coast,” Phivolcs said.
