Lava effusion at Mayon led today’s activity, with multi-kilometer flows still moving down three gullies. Guatemala’s Fuego produced frequent explosions with kilometer-scale plumes, while Ecuador’s Sangay and Reventador logged dozens of blasts and hot rockfalls. In the United States, Great Sitkin held at Watch/Aviation ORANGE as Kilauea’s eruption remained paused.

United States
Great Sitkin (Watch / Aviation ORANGE) kept up its long-running eruption. Kilauea remained in an eruptive pause (Advisory; Aviation YELLOW). Unrest continued at Kupreanof and Shishaldin (both Advisory; Aviation YELLOW).

Indonesia
Eruptive activity persisted at Merapi, Semeru, and Lewotobi (the last two at Level 3 – Standby). Several others—Dukono, Ibu, Lewotolok, and Marapi—also remained in eruption at Level 2. Unrest continued at Krakatau and at numerous volcanoes across Sulawesi, Maluku, and Java; see the table for the full list. Tangkuban Parahu stayed at Normal status (Level 1).

Philippines
At Mayon, lava continued to pour from the summit, with flows 3.8 km E, 3.2 km SE, and 1.7 km S; plumes rose to ~1.3 km and monitoring recorded frequent rockfalls, tremor, and PDC signals. Unrest persisted at Bulusan with a 200 m plume, 148 seismic events, and inflation, while Taal held at Level 1 and Kanlaon remained at Level 2.

Mexico
Popocatepetl remained in eruption under Yellow Alert – Phase 2.

South America
Ecuador’s Reventador produced 74 explosions along with incandescent rockfalls descending up to 1 km below the crater. Nearby, Sangay tallied 76 explosions with ash-and-gas plumes reaching 1 km; thermal anomalies were noted at both. Peru’s Sabancaya continued its eruption at Orange Alert.

Other
In Guatemala, Fuego generated up to 10 explosions per hour with plumes to about 1 km above the vent. Santa Maria also produced occasional explosions with plumes rising as high as 800 m.
