Two more short-lived phreatomagmatic bursts were recorded at the restive Taal Volcano on Wednesday morning, Nov. 17, the Philippine Institute of Volcanology and Seismology (Phivolcs) said in a volcano advisory.

Phivolcs said the bursts occurred at 1:46 a.m. and 2:54 a.m. and produced 400-meter to 500-meter plumes.

"There have been three phreatomagmatic bursts since November 15 that are likely driven by fracturing and gas release from resting magma beneath the Taal Volcano Island," Phivolcs pointed out.

Phreatomagmatic burst occurs when hot magma comes into contact with groundwater.

Phivolcs said that Taal Volcano remains under alert level 2, which means that the volcano continues to manifest "increased unrest."

"At Alert Level 2, sudden steam- or gas-driven explosions, volcanic earthquakes, minor ashfall, and lethal accumulations or expulsions of volcanic gas can occur and threaten areas within and around TVI," it said.

The volcano has been under alert level 2 since July 23, 2021.

Phivolcs reiterated that entry into the Taal Volcano Island, which is a permanent danger zone, especially the vicinities of the main crater and the Daang Kastila fissure, is strictly prohibited.

Boating on Taal Lake is also prohibited, it said.
