Stromboli (Eolian Islands, Italy): A short period of elevated lava spattering produced a short-lived lava flow from the northern crater area to the upper Sciara del Fuoco yesterday afternoon from around 16:25. The flow lasted only a few hours at most and traveled about 100 m on the upper slope.
Overall, the volcano has been at elevated activity level during the past weeks. This isn’t based only on the visible activity (e.g. the size of strombolian explosions, which hasn’t been particularly strong), but takes into account other geophysical parameters detected by instruments, which reflect a state of elevated internal activity of the volcano: in particular, CO2 and SO2 gas emissions as well as a particular type of volcanic quakes (LP events) have been at significantly higher levels than during most times. These all indicate that magma supply at depth is higher than normal. This in turn is likely to result in increased activity at the surface in a short to medium term future.
Etna (Sicily, Italy): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Toulouse warned about a volcanic ash plume that rose up to estimated 15000 ft (4600 m) altitude or flight level 150 and is moving at 25 kts in E direction.

…26 Jun:
Following the short lava-fountaining episode Thursday noon, which had been remarkable by the dual activity of a new lava flow from a flank fissure and the fountaining at the summit, the volcano produced two similar eruptions in rapid succession yesterday, one in the morning and one in the evening:
The first one announced itself early on Friday (25 June 2021), when strombolian activity started at the New SE crater again from 01:17 am local time, while the lava flow from the effusive vent at the SE base of the cone at around 3050 m elevation continued to be active and formed two main branches into the upper Valle del Bove.
