Phivolcs records increase in Mayon Volcano sulfur dioxide emissions

Philippine Daily InquirerIndependentCenternow

Mayon Volcano in Albay, Philippines, experienced an effusive eruption for the 187th consecutive day on July 11, 2026, according to the Philippine Institute of Volcanology and Seismology (Phivolcs). Lava flows, pyroclastic density currents ('uson'), and rockfalls were observed during the event, which lasted from 4:11 a.m. to 4:40 a.m. Monitoring data indicated 10 volcanic earthquakes, 241 rockfall events, and six PDCs over the previous 24 hours. Sulfur dioxide emissions reached 8,239 tons on Friday, higher than the previous day's total. Despite these developments, the volcano remains under Alert Level 3, prohibiting entry into a six-kilometer radius and restricting air traffic near the area. Nearby communities are warned of potential hazards including rockfalls, lava flows, and lahars.

Thin ashfall from Mayon Volcano impacted several villages in Bacacay, Albay on July 10, 2026. The ashfall occurred alongside strong winds and rains caused by the enhanced southwest monsoon and Typhoon Inday. Local authorities, including Mayor Daniel Jose 'Nookie' Bombales, distributed face masks to residents and advised them to wear masks when outdoors and keep windows and doors closed. The Philippine Institute of Volcanology and Seismology (Phivolcs) reported ongoing volcanic activity, including lava flows reaching up to 3.8 kilometers along certain gullies.

The Philippine Institute of Volcanology and Seismology (Phivolcs) reported a significant rise in sulfur dioxide (SO2) emissions from Mayon Volcano in Albay. On Thursday, the average daily SO2 flux was 4,569 tonnes, increasing to 7,475 tonnes per day on Friday—the highest level recorded in the past 16 years. This surge follows an ongoing eruption that began on January 6, during which the average daily SO2 emissions have been around 2,300 tonnes. Phivolcs warned that rising SO2 levels may indicate further eruptive activity and potential increases in volcanic hazards, especially due to poor weather conditions. However, there has been a decrease in rockfall events and pyroclastic density currents, suggesting reduced lava flow from the summit crater. Despite these changes, Mayon remains under Alert Level 3, indicating eruptive unrest, and residents within a six-kilometer radius are urged to remain outside the danger zone.
