Taal Volcano sulfur dioxide emission up, says PHIVOLCS

Taal Volcano's daily emission of sulfur dioxide increased on Monday, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said Tuesday.

In its 5 a.m. volcano bulletin, PHIVOLCS said 9,391 tons of sulfur dioxide were released from the volcano, which is higher compared to the 5,831 tons recorded on Thursday, June 1.

Alert Level 1 remained over Taal Volcano, signifying low-level unrest.

A pronounced upwelling of hot volcanic fluids in the Main Crater Lake and vog or volcanic smog were observed over the volcano, according to PHIVOLCS.

A voluminous plume reaching up to 1,800 meters tall was also seen drifting northwest from the volcano, PHIVOLCS added.

One volcanic tremor was recorded in Taal at 6:35 a.m. on Friday, June 2, it also said.

PHIVOLCS also said a short-term inflation of the northwestern sector of Taal and a long-term deflation of the Taal Caldera were monitored.

On February 21, the acidity level of the Main Crater Lake was at 0.48.

On April 27, the temperature of the Main Crater Lake was at 74.1 ?.

PHIVOLCS warned of possible steam-driven or phreatic or gas-driven explosions, volcanic earthquakes, minor ashfall, and lethal accumulations or expulsions of volcanic gas in Taal.

"The entry into Taal Volcano Island (Permanent Danger Zone or PDZ) especially the Main Crater and Daang Kastila fissures, occupancy and boating on Taal Lake, as well as flying any aircraft close to the volcano are prohibited," said PHIVOLCS. —Joviland Rita/KBK, GMA Integrated News
