Global volcanic activity saw sustained eruptions across multiple continents through early August 2026, with monitoring agencies tracking persistent ash emissions, explosions, and dome growth at several high-risk peaks. According to reports from the Smithsonian Institution’s Global Volcanism Program and regional geological observatories, heightened unrest continued at active systems in Latin America, Indonesia, and Russia.
Latin American Volcanoes Maintain High Activity Levels
Guatemala’s Fuego volcano remained in a state of active unrest through early August 2026, producing frequent low-to-moderate explosions and ash plumes.
In Mexico, Popocatépetl maintained persistent low-level activity. Further south, Santiaguito in Guatemala and Reventador in Ecuador also registered ongoing dome growth and minor seismic signals consistent with baseline eruptive phases.
Indonesian Peaks Show Persistent Ash Plumes
According to the Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG), Mount Semeru in East Java produced discrete ash explosions that drifted downwind.
Mount Ibu, located on Halmahera Island, sustained frequent explosive activity, sending thick gray ash columns thousands of feet into the atmosphere.
Russian and Regional Eruptions Tracked by Observatories
In Russia’s Far East, Sheveluch volcano on the Kamchatka Peninsula continued its protracted dome extrusion process.
