Map of today's active volcanoesEtna (Sicily, Italy): A powerful sudden explosion occurred at the Bocca Nuova summit crater today at 1:12 pm local time. The eruption lasted a few minutes only and created an ash column that rose approx. 1,500 m above the summit before dispersing to the northeast.Light ashfall occurred in the upper part of the volcano. ... [read more] ... [show less] The explosion was not preceded by any detected precursory sign and likely did not involve new magma, but was caused by sudden explosion of overheated water inside the conduits (so-called phreatic activity). Such sudden, but very violent explosions are a serious hazard for climbers in the summit region and can occur during apparent phases of calm at the volcano and have no warnings. A similar event occurred on August 25, 2010, also at the Bocca Nuova crater.Svartsengi (Reykjanes peninsula, SW Iceland): (4 Mar) The Icelandic Met Office (IMO) reported that magma under the Svartsengi region has been accumulating over the past 210 days.If this trend of the ongoing ground uplift will persist, the total volume of accumulated magma may exceed that observed between previous eruptive events since the onset of the ongoing eruption sequence. ... [read more] ... [show less] Although the rate of magma supply remains relatively slow, it has been consistent in recent weeks. The combination of a large accumulated magma volume and the extended recharge period has prompted the Icelandic Meteorological Office to undertake further analysis of the system. In response, the agency is revising its eruptive scenarios to better evaluate potential developments in volcanic activity; updated assessments are expected to be released in the coming weeks.Current estimates indicate that roughly 22.5 million cubic meters of magma have accumulated since the most recent eruption in July of last year. Importantly, the prolonged interval without eruptive activity should not be interpreted as definitive evidence that the ongoing eruption sequence has concluded.Canlaon (Central Philippines): The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported that the eruption continued at Kanlaon on 3 March 2026 (local).
