The Philippine Institute of Volcanology and Seismology (Phivolcs) raised the alert level for activity at Bulusan volcano (Bicol region) from level zero (the lowest level on a six-tier scale) to level one (the second level on a six-tier scale) on Monday, July 6. The alert came following the recording of 53 volcanic earthquakes since Friday, June 3, which Phivolcs warned could produce steam-driven eruptions at the summit or on vents on the volcano's flank. Local authorities continue to maintain a 4 km (2 miles) Permanent Danger Zone around the volcano with entry to this area remaining prohibited.
A sudden phreatic or steam-driven eruption is possible in the coming hours or days, which could threaten communities in the surrounding area.
There is a credible threat of volcanic eruptions in the Philippines due to the presence of several active volcanoes. The impact varies depending on the eruption's intensity, although common threats include human casualties and displacements, structural damage, and travel disruptions. In January 2020, an eruption on Taal Volcano Island led to the evacuation of more than 300,000 residents living within the 14-kilometre (8.6-mile) "danger zone". Large eruptions such as these, which typically occur once a century in each active site, can cause significant devastation with little warning.
Individuals present in the affected area are advised to avoid the vicinity of the volcano, monitor the situation, anticipate transportation disruptions, and adhere to any instructions issued by the local authorities (e.g. evacuation orders).
