Phivolcs remains on alert as vog clears over Taal Volcano

MANILA, Philippines — The thick volcanic smog or "vog" covering Taal Volcano in Batangas for days cleared on Saturday morning, but Phivolcs warned that the volcano's threat persists.

In an interview on Dobol B TV, Phivolcs Director Dr. Teresito Bacolcol, noted a significant improvement in visibility around Taal Volcano on Satutday.

"'Yung nangyari nu'ng September 21 hanggang kahapon na halos zero visibility na ang Taal Volcano, ngayon, nagki-clear na po, nakikita na ang Taal Volcano.'Yung vog na nag-envelope sa caldera ay nawala na po this morning," Bacolcol said.

(Taal Volcano is now visible, in contrast to the near-zero visibility experienced from last September 21 until yesterday, with the vog that had covered the volcano's caldera dissipating this morning).

"This will be a recurring threat. As long as the Taal Volcano is spewing sulfur dioxide, the threat will always be there," he added.

Over the last 24 hours, sulfur dioxide emissions from Taal Volcano decreased to 2,730 tons per day, down from 4,569 tons per day on Thursday, September 21.

Bacolcol explained that the quantity of sulfur dioxide emissions does not suggest an imminent eruption.

"Hindi ito nangangahulugan na magkakaroon ng eruption. 'Yung inilalabas na sulfur dioxide ng Taal Volcano, hindi 'yan considered na mataas for Taal Volcano. Hindi lang makaangat dahil sa thermal inversion. The lower part, malamig, nahaharangan ang pag-angkat sa mainit na layer sa atmosphere," he said.

(These factors do not indicate an imminent eruption because the amount of sulfur dioxide emitted by Taal Volcano is not high, and it cannot rise higher due to a thermal inversion where the lower part is cold, and the upper layer is hot.)
