Updates on volcanic activity (Smithsonian)
The Smithsonian/USGS Weekly Volcanic Activity Report provides information about global volcanism on a weekly basis. Latest Mayon report has been published on 06 Feb 2026 07:13.
The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported that the eruption at Mayon continued during 28 January-4 February, characterized by effusion and collapses at the summit dome, pyroclastic density currents (PDCs), rockfalls, ash plumes, avalanches of incandescent material, and lava flows. Episodic and minor Strombolian activity was visible on 28 January. Moderate emissions rose as high as 1 km above the summit and drifted in various directions during 28-30 January and on 4 February; weather clouds obscured views on the other days. The seismic network recorded 284-389 daily rockfall events and 26-68 daily PDCs. The number of volcanic earthquakes recorded was variable: 119 on 28 February, 21 on 29 February, and 0-9 daily the rest of the week. Sulfur dioxide emissions increased each day, averaging 1,275 tonnes per day (t/d) on 28 January and rising to 5,297 t/d by 3 February. Sulfur dioxide emissions peaked at 6,569 t/d on 4 February, the highest average recorded in the past 15 years.
According to a news report ashfall was reported on 2 February in at least five villages including Quirangay, Sua, Tumpa, Libod and Anoling. Ash fell with rain causing reduced road visibility and affecting local farmlands. By 1800 on 4 February a total of 4,058 people (1,115 families) were staying in 13 evacuation shelters, and an additional 53 people (17 families) were staying with friends or relatives, according to the Disaster Response Operations Monitoring and Information Center (DROMIC). The Alert Level remained at 3 (on a 0-5 scale) and residents were reminded to stay away from the 6-km-radius Permanent Danger Zone (PDZ). PHIVOLCS recommended that civil aviation authorities advise pilots to avoid flying close to the summit.
