Philippines’ Bulusan Volcano Could Erupt Anew
Phivolcs Issues Fresh Warning on Bulusan Activity
The Philippine Institute of Volcanology and Seismology (Phivolcs) has issued an alert warning that Bulusan Volcano in Sorsogon may erupt again in the coming days. The advisory follows increased seismic activity and gas emissions detected around the volcano’s summit.
Alert Level Maintained at 1, But Risks Remain
While Phivolcs has maintained Bulusan’s status at Alert Level 1, indicating low-level unrest, the agency cautioned that conditions remain volatile. The alert level reflects the presence of hydrothermal processes beneath the volcano that could lead to phreatic or steam-driven eruptions.
Recent Activity Triggers Heightened Surveillance
In the past 48 hours, Phivolcs has recorded a series of volcanic earthquakes and ground deformation signals in the vicinity of Bulusan. These indicators suggest ongoing movement of subsurface fluids, raising the likelihood of an explosive, though short-lived, eruption.
Gas Plumes Signal Elevated Volcanic Activity
Phivolcs monitoring teams also reported increased emission of sulfur dioxide gas, with plumes rising as high as 800 meters above the summit crater. Elevated sulfur dioxide levels are often a precursor to eruptive activity, as they indicate the release of magma-heated gases.
Communities Near Volcano Urged to Stay Vigilant
Authorities have advised residents living within a 4-kilometer permanent danger zone to remain vigilant and ready to evacuate if necessary. Local governments have been instructed to activate contingency plans and ensure emergency resources are on standby.
Previous Eruptions Offer Sobering Context
Bulusan last erupted in June 2022, spewing ash that blanketed surrounding villages and disrupted air travel in parts of southern Luzon. That eruption caused minor damage to agriculture and forced temporary school and office closures in nearby towns.
Evacuation Plans Reviewed by Local Authorities
In response to the new warning, local disaster risk reduction and management councils (DRRMCs) are reviewing evacuation protocols and updating logistical plans. Temporary shelters and supply caches are being prepared to support potential evacuees.
Residents Report Anxiety and Preparedness Measures
Communities in towns such as Juban and Irosin have expressed both concern and readiness. Many residents have begun stockpiling basic supplies and reviewing evacuation routes. Public announcements and community drills have increased to raise awareness.
Travel and Tourism Restrictions Imposed
Phivolcs has advised the public, particularly hikers and tourists, to avoid entering the volcano’s slopes and summit area. Trekking and ecotourism activities in Bulusan Volcano Natural Park have been temporarily suspended to ensure public safety.
Agricultural Sector Faces Potential Disruption
Farmers around Bulusan are bracing for the possible impact of an eruption on crops and livestock. Volcanic ash can damage plant leaves, contaminate water sources, and reduce air quality—posing threats to livelihoods and public health alike.
Emergency Response Agencies on High Alert
The National Disaster Risk Reduction and Management Council (NDRRMC) has placed emergency response teams on alert. Coordination between local government units, health agencies, and security forces has been heightened in case of rapid escalation.
Volcanic Hazards Include Ashfall and Lahar Flows
Phivolcs has warned that, in the event of an eruption, nearby communities could experience ashfall and possible lahar flows—mudslides composed of volcanic material and water. These secondary hazards can occur even after the eruption has ceased.
Schools and Clinics Briefed on Safety Protocols
Educational institutions and local health clinics have been briefed on emergency procedures. Mask distribution and air quality monitoring have begun in vulnerable areas, especially in anticipation of ash-related respiratory issues.
Public Urged to Follow Official Updates
Phivolcs and the Department of Science and Technology (DOST) continue to issue regular bulletins via online platforms, radio, and television. Citizens are strongly urged to rely only on official channels and avoid spreading misinformation on social media.
Conclusion: Caution and Preparedness as Bulusan Stirs
As Bulusan Volcano shows signs of renewed unrest, authorities and communities across Sorsogon are adopting a posture of caution and readiness. While no eruption has yet occurred, the warning from Phivolcs is a reminder of the dynamic nature of the Philippines’ volcanic landscape. Vigilance, clear communication, and timely response will be crucial in minimizing the impact of any potential eruption.
