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 an overview of recent developments as of February 27, 2026, focusing on Stromboli, Italy, and other notable volcanic regions.

Stromboli, Italy: Continuing Eruptive Activity

Eruptive activity at Stromboli continues, with the Instituto Nazionale di Geofisica e Vulcanologia-Osservatorio Etneo (INGV-Osservatorio Etneo) reporting ongoing eruptions 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 reports from November 2025 detailed Strombolian activity at five vents in the Sciara del Fuoco and at least two vents on the crater terrace.

Stromboli, one of the most consistently active volcanoes in the world, is located on the northernmost of the seven Eolian Islands, north of Sicily. The volcano’s current activity is centered on the Sciara del Fuoco, a steep slope on the northwest side of the volcano.

Shiveluch, Kamchatka

Visual observations confirm new dome growth at Shiveluch, with ash plumes reaching 9 km above sea level. Seismic activity indicates hot avalanches on the western slope.

Kusatsu-Shirane, Honshu, Japan

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

An explosive eruption was recorded at Canlaon on February 26, 2026, producing a plume 2,500 m above the vent and pyroclastic density currents descending the east and southeast flanks. The alert level remains at “2 – Moderate Level of Volcanic Unrest” (on a 0–5 level scale).

Taal, Luzon, Philippines

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 continues from the summit crater of Mayon. Lava flows currently extend 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. The alert level remains at “3 – Increased Tendency Towards Hazardous Eruption” (on a 0–5 level scale).
