Mount Bulusan
Also known as: Bulusan Volcano
Definition
Mount Bulusan is an active stratovolcano rising 1,565 meters in Sorsogon province at the southeastern tip of Luzon, within Bulusan Volcano National Park, one of the country’s earliest national parks. The volcano’s summit crater holds a small lake known as Blackbird Lake, and its flanks, cloaked in rainforest, host lakes, hot springs, and settlements devoted to abaca and farming. Monitored continuously by PHIVOLCS, Bulusan is known for sudden phreatic, steam-driven explosions, with notable episodes in 2006-2007, 2010-2011, and June 2022 that dumped ash on surrounding towns.

Examples and Analogies
Bulusan is to Sorsogon what Hibok-Hibok is to Camiguin: a small but abruptly explosive volcano whose phreatic bursts arrive with little warning, like a kettle blowing its lid rather than a slow-boiling lava eruption. Its crater lake and rainforest park make it a Bicol analogue of Taal, a living volcano doubling as a scenic protected area.
Usage Scenarios
Bulusan anchors local disaster-preparedness drills, PHIVOLCS alert-level education, and volcano tourism, including lake visits, forest trails, and hot springs, while its slopes figure in abaca-based rural livelihoods and Bicol regional tourism circuits.
Strategies
Management strategy couples PHIVOLCS monitoring and a four-kilometer-radius permanent danger zone with local evacuation planning, ashfall advisories for aviation and health, and park-based conservation of its rainforest and watersheds.
Security and Safety Measures
Safety practice bars entry within the danger zone, requires masks and roof-cleaning guidance during ashfall, and maintains lahar watch on drainages after heavy rain loosens deposited ash, coordinated through provincial and municipal disaster councils.
Historical Context
Bulusan has erupted repeatedly since Spanish-era records of the nineteenth century, with major explosions in the early 1900s shaping early volcanological study in Bicol. The national park was proclaimed in the 1930s, and PHIVOLCS monitoring intensified after the 2006-2007 and subsequent unrest episodes, including the June 2022 phreatic eruption.
Challenges and Controversies
Phreatic explosions are notoriously hard to forecast, straining alert systems and testing the balance between safety rules and farmers’ access near the danger zone. Recurring debates concern settlement and quarrying on volcanic slopes, compensation for ash-damaged farms, and the weight of park regulations on upland residents.
