CANLAON CITY, Philippines — The Philippine Institute of Volcanology and Seismology (PHIVOLCS) has raised ashfall alerts for several communities surrounding Kanlaon Volcano following a series of phreatic eruptions and increased seismic activity. As of Saturday, March 21, 2026, state volcanologists have warned residents in Negros Oriental and Negros Occidental of potential health risks and agricultural damage as the volcano remains under Alert Level 2.
The volcanic unrest comes at a particularly challenging time for the region. While the Amihan (Northeast Monsoon) is fading, the prevailing Easterlies are shifting ash clouds toward highly populated agricultural hubs. This natural threat adds a layer of complexity to the “diesel double whammy” and the Peso sliding past ₱60 vs $1, which have already driven up the cost of emergency logistics and farm inputs across the Visayas.
“We are monitoring a continuous increase in volcanic earthquakes and sulfur dioxide emissions,” a PHIVOLCS duty officer stated. “Residents are advised to wear N95 masks and stay indoors if ashfall is observed. For our farmers, covering water sources and crops is essential to prevent contamination, especially as the sugar sector is already struggling with high production costs and import pressures.”
- Ashfall and Respiratory Health: Health officials in Bacolod and Dumaguete are distributing face masks to vulnerable populations. Fine ash particles can exacerbate respiratory issues, a concern echoed by teacher-leaders like Ruby Bernardo, who are advocating for “health breaks” in affected schools.
- Agricultural Impact: The ashfall is a direct threat to the sugar industry in Negros, which is currently at its peak milling season. Volcanic ash can damage standing sugarcane and contaminate the water used for solar-powered irrigation, further squeezing the margins of local planters.
- Aviation and Logistics: Civil aviation authorities have issued a “Notice to Airmen” (NOTAM) to avoid flying near the volcano’s summit. This disruption comes as the Holy Week rush begins, potentially affecting regional flights and the delivery of essential goods.
- Civil Defense Readiness: Local Government Units (LGUs) have activated evacuation centers, utilizing a portion of the ₱21.47-billion relief package and BIR collection surplus to fund emergency food packs and medical supplies.
The escalation of Kanlaon’s activity coincides with a period of national “Inflation Shield” efforts, such as the 60-day price freeze on processed foods and toll cuts. However, for families in the path of the ashfall, the immediate focus is on physical safety and the protection of their livelihoods.
Local transport groups, including members of PISTON, have expressed concern that falling ash mixed with light rain could create slippery road conditions, making the daily commute even more hazardous for jeepney drivers who are already earning only ₱200–₱300 daily.
As the second quarter of 2026 begins, the “twin threats” of volcanic unrest and economic volatility are testing the resilience of the Visayas. While the Philippine banking system holds firm with over ₱36 trillion in resources, the immediate “ground-level” priority remains the safety of those living under the shadow of Kanlaon.
