Aside from this, a crater glow can be observed while the volcano edifice remains inflated, Phivolcs said. 

The volcano also released 2,539 tons of sulfur dioxide on Friday, which was more than the 1,624 tons recorded a day before, it added.

Phivolcs said the volcano emitted a plume that rose 100 meters above the crater and drifted northwestward and west-southwestward.

The agency said the volcano remains under Alert Level 3, which signifies intensified or magmatic unrest. Entry into the volcano’s six-kilometer radius, or the permanent danger zone, is prohibited, and aircraft are banned from flying close to the volcano. 

Phivolcs reminded nearby residents of possible hazards, such as rockfalls, landslides or avalanches, ballistic fragments, lava flows, PDCs, moderate-sized explosions, and lahars. /das
