A quick update on the ongoing explosions at Bulusan in the Philippines. The volcano is still in a state of unrest, with frequent small explosions producing minor ash falls around Bulusan. This comes after a much larger explosion that occurred on Sunday (see below) of this week. That explosion was large enough to prompt evacuations of the area near the volcano – and for the Philippine government and the New People’s Army to call a truce in the area near Bulusan. All of this in the name of relief efforts for the people who had to leave their homes, which right now stands at ~3,500 people in 11 shelters. Since Sunday, the volcano has calmed down, with fewer earthquakes under the edifice than before the weekend and sulfur dioxide emissions at ~10 tonnes/day. with Most of the ash from Sunday’s explosion has been cleared. However, despite all this drama, PHIVOLCS has kept Bulusan at Alert Level 1 (of 4) as they still have not seen signs of new magma in the eruptive products from these explosions.
