Bulusan Volcano's sulfur dioxide emission almost doubles

The amount of sulfur dioxide emitted by Bulusan Volcano in Sorsogon in the past 24 hours almost doubled compared to the previous reported emission, data from the Philippine Institute of Volcanology and Seismology (PHIVOLCS) showed.

A total of 1,155 tonnes of sulfur dioxide was emitted by the volcano on July 8, PHIVOLCS said in its bulletin on Saturday.

On July 6, sulfur dioxide flux was at 632 tonnes

Five volcanic earthquakes were recorded from 5 a.m. Friday to 5 a.m. Saturday, PHIVOLCS said.

Meanwhile, plumes measuring 100 meters tall were seen rising from the volcano. These plumes drifted north-northwest.

The volcano edifice remains inflated, PHIVOLCS said.

Alert Level 1 (low-level unrest) remains in effect over Bulusan Volcano, it added.

PHIVOLCS reminded the public that entry into the 4-km permanent danger zone (PDZ) and entry without vigilance into the extended danger zone (EDZ) is prohibited.

Likewise, flying aircraft close to the volcano is not allowed.

PHIVOLCS said sudden steam-driven or phreatic eruptions may occur. —KG, GMA News
