Shiveluch (Kamchatka): (27 Feb) Visual field observations from local scientists confirmed a new dome growth from the active Young Shiveluch dome that started in December last year.
The new lava dome is located on the western part of Young Shiveluch. The new dome’s activity is accompanied by ash plumes reaching an altitude of 9 km above sea level, its current height already surpassed the Young Shiveluch’s height.

The seismic instrument continues to detect volcanic tremor reflecting hot avalanches racing down the western slope.

Canlaon (Central Philippines): The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported that the eruption continued at Kanlaon on 26 February 2026 (local). At 1904 on 26 February, a moderately explosive eruption was recorded at the summit crater, lasting 2 minutes (according to seismic and infrasound data). The eruption plume rose 2,500 m above the vent and drifted SW. Incandescent volcanic ballistic projectiles were ejected around the crater area. Pyroclastic density currents (PDCs), or pyroclastic flows, descended the E and SE flanks within 2 km of the summit crater. Immediately following the explosive eruption, a continuous ash emission persisted for approximately 71 minutes. The alert level remained at “2 – Moderate Level of Volcanic Unrest” (on a 0–5 level scale).
