Frequent explosive activity in Indonesia and Guatemala stood out today, while Hawaii’s Kilauea slipped into a pause. Popocatepetl’s ground alert shifted to Orange, and Italy’s Stromboli showed both Strombolian bursts and effusive lava.
United States Great Sitkin (Watch / Aviation ORANGE) kept slow lava effusion inside the summit crater with weak steaming; rockfalls from the growing dome were detected. At Kilauea (Advisory / Aviation YELLOW), eruptive activity paused, but glow persisted at vents and the crater-floor flows stayed incandescent. Unrest at Shishaldin (Advisory / Aviation YELLOW) produced vapor plumes, SO2 degassing, and intermittent thermal anomalies.
Indonesia Halmahera’s Dukono and Ibu were notably noisy, with 82 and 126 explosions respectively; ash rose up to 1.5 km at Dukono and to 600 m at Ibu. Farther south, Semeru tallied 74 explosions with ash to 800 m, while Merapi shed hot avalanches reaching 2 km and Marapi produced two explosions. On Flores and Lembata, Lewotobi and Lewotolok emitted low gas plumes and minor rockfalls. Several others were in unrest at Indonesia’s Level 2 Alert, including Krakatau, Kerinci, Raung, and more.
Philippines At Mayon (Alert Level 3), lava effusion kept three flows active at 3.8 km (Basud), 3.2 km (Bonga), and 1.6 km (Mi-isi), with minor Strombolian bursts and numerous rockfalls; occasional PDC-related signals were recorded. Nearby, Kanlaon logged seven ash emissions with plumes to 600 m and SO2 at 1,891 t/d. Low-level unrest persisted at Taal (Alert Level 1) and Bulusan (Alert Level 1), with diffuse plumes, minor seismicity, and ongoing inflation.
Mexico Popocatepetl shifted to an Orange alert as ash-and-gas emissions continued; a M1.5 volcano-tectonic quake was recorded.
South America In Ecuador, Reventador and Sangay produced frequent explosions and ash plumes (to 1 km and 800 m, respectively), along with incandescent rockfalls. Peru’s Sabancaya sent ash-and-gas up to 1.2 km and showed occasional thermal anomalies.
Europe Italy’s Stromboli (Aviation ORANGE) featured classic Strombolian bursts alongside effusive lava, with rockfalls and tremor.
Other In Guatemala, Fuego averaged up to 13 explosions per hour, lofting ash to 937 m and throwing incandescent material with accompanying rockfalls, while Santa Maria produced up to two explosions per hour with ash to 800 m and persistent dome glow. In Costa Rica, degassing persisted at Poas, while Rincon de la Vieja and Turrialba remained at Level 2 (Warning) with Aviation Yellow.
