Global Volcanic Activity: Updates from Stromboli and Beyond – February 27, 2026

Volcanic activity continues across the globe, with ongoing eruptions and unrest at multiple sites. This report provides updates on several key volcanoes as of February 27, 2026, drawing on the latest reports from international monitoring agencies.

Stromboli (Italy) – Continuing Eruption

Eruptive activity at Stromboli continues, with the Instituto Nazionale di Geofisica e Vulcanologia-Osservatorio Etneo (INGV-Osservatorio Etneo) reporting ongoing activity on February 26, 2026. The alert level remains at “Yellow” (level 2 on a 4-level scale), while the aviation alert level is at “Orange” (level 3 on a 4-level scale). Recent observations from November 2025 indicated Strombolian activity at five vents in the Sciara del Fuoco and at least two vents on the crater terrace.

Stromboli, one of Italy’s most active volcanoes, is located on the northernmost of the seven Eolian Islands, north of Sicily. The volcano’s base lies approximately 2000 meters below sea level, with its summit reaching over 920 meters above sea level. The current active vents are located about 200 meters below the summit.

Other Notable Volcanic Activity

Shiveluch (Kamchatka, Russia) – Dome Growth and Ash Plumes

A recent lava dome is growing at Shiveluch, with ash plumes reaching altitudes of up to 9 km above sea level. Seismic activity indicates hot avalanches on the western slope.

Kusatsu-Shirane (Honshu, Japan) – Continued Unrest

Unrest continues at Kusatsu-Shiranesan, with the alert level remaining at “Level 2 – Restriction on proximity to the crater” (on a 5-level scale).

Canlaon (Central Philippines) – Explosive Eruption

An explosive eruption occurred at Canlaon on February 26, 2026, producing a plume rising 2,500 meters above the vent and drifting southwest. Pyroclastic density currents descended the east and southeast flanks within 2 km of the summit. The alert level remains at “2 – Moderate Level of Volcanic Unrest” (on a 0–5 level scale).

Taal (Luzon, Philippines) – Low-Level Unrest

The eruption at Taal continues, with the alert level remaining at “1 – Low-Level Unrest” (on a 0–5 level scale).

Mayon (Luzon Island, Philippines) – Lava Effusion and Emissions

Lava continues to effuse from Mayon’s summit crater, with flow lengths of 3.8 km in the Basud Gully, 2.6 km in the Bonga Gully, and 1.3 km in the Mi-isi Gully. Sulfur dioxide emissions averaged 2,199 tonnes per day on February 26, 2026. The alert level remains at “3 – Increased Tendency Towards Hazardous Eruption” (on a 0–5 level scale).

Indonesia – Multiple Volcanoes on Alert

• Semeru (East Java): Alert level “Level 3 – Standby”
• Marapi (Western Sumatra): Alert level “Level 2 – Alert”
• Dukono (Halmahera): Alert level “Level 2 – Alert”
• Kerinci (Sumatra): Alert level “Level 2 – Alert”
• Lokon-Empung (North Sulawesi): Alert level “Level 2 – Alert”

Other Global Activity

• Aoba (Vanuatu): Minor eruption ongoing.
• Great Sitkin (Aleutian Islands, Alaska): Eruption continues with lava flow.
• Kilauea (Hawai’i): Pause in eruptive activity reported.
• Shishaldin (Aleutian Islands, Alaska): Unrest continues.
• Sangay (Ecuador): Explosive activity continues.
• Reventador (Ecuador): Explosive activity continues.
• Piton de la Fournaise (La Réunion): Effusive eruption continues.

Conclusion

Volcanic activity remains dynamic across the globe. Continued monitoring and assessment by geological agencies are crucial for mitigating risks and ensuring public safety. This is a snapshot of the current situation as of February 27, 2026, and conditions can change rapidly.
