Map of today's active volcanoesStromboli (Eolian Islands, Italy): During 3–9 August 2026, Stromboli produced normal strombolian explosions with high intensity as well as spattering from the North crater area and three modest lava overflows from the N1 vents. The flows remained confined to the upper Sciara del Fuoco. Overall explosive frequency was medium, with no significant changes in monitored seismicity or ground deformation.Etna (Sicily, Italy): The ongoing eruption is intensifying with near-continuous explosive activity and ash emissions from the Voragine summit crater, as well as the opening of two more eruptive fissures further downslope: yesterday evening, a new effusive vent opened at around 23:30 local time in the Valle del Bove at an elevation of approximately 1,900 m near the Monte Simone cinder cone, followed by another effusive vent that opened 12 hours later this morning, at around 11:30 local time, not far away at the northern headwall of the Valle del Bove depression.This indicates a significant migration of eruptive activity downslope: the previous effusive vents had been at elevations of approximately 2,750 and 2,360 meters, respectively. ...

[show less] According to the volcano observatory who surveyed the area today, the furthest lava flow fronts had passed the area of Rocca delle Palombe and was at an elevation of approximately 1,370 meters earlier today. Being confined inside the vast Valle del Bove, the flows currently pose no threat to populated areas.In the meantime, intense explosive activity continues from the summit craters, primarily the Voragine crater, producing large amounts of ash rising up to approx. 5,000 m altitude and being carried southwards. Due to the southerly distribution of the ash plume towards the city of Catania, many flights from Catania airports have been canceled or needed to be diverted. Disruptions for travelers coincide with the absolute peak of the tourist season.Sakurajima (Kyushu, Japan): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTED AT 20260811/1415Z FL090 STNR OBS VA DTG:11/1410ZIbu (Halmahera, Indonesia): Explosive activity continues.
