Etna (Sicily, Italy): (13 Jun) Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Toulouse warned about a volcanic ash plume that rose up to estimated 22000 ft (6700 m) altitude or flight level 220 and is moving at 15 kts in S direction.

...12 Jun:
A powerful paroxysm - or lava fountaining episode - is in progress at the volcano now at the SE crater. After a week of activity fluctuating between moderate and high levels, Etna decided again to escalate into a short-lived phase of intense lava fountains.
This episode comes about a week since the last one on 4 June. In the time between, the volcano had not calmed down as usual during intervals, but remained active with weak to moderate strombolian activity from the crater, and moderate to high tremor levels, indicating that the magma column had not subsided a lot since.

The newest episode this evening began to produce lava fountains from around 21:45 pm local time and lasted until about midnight. This time, the activity was noticeable stronger than during the previous shorter episodes observed in late May and more similar to typical paroxysms such as those in February and March earlier this year.


Fagradalsfjall (Reykjanes Peninsula, Iceland): This morning, a lava flow escaped from the Geldingadalir valley at its southern rim, crossed the hiking trail A (which was leading to the observation hills southeast of the active cone), and made its way to the already existing lava flow field in the Nátthagi valley to the SE.
Geldingadalir valley by now is largely filled with lava flows, which continue to pile up layer by layer, and, importantly, by inflation of the still liquid lava body under the mostly solidified crusts. As it thus gradually increases the height of the surface, it allows lava to spill over increasingly wide sections of the enclosing rims.

As to the activity, effusion of lava continues at more or less constant pace, but the pulsating, "geyser-like", rhythmic behavior of strong up-welling and fountaining roughly every 10 minutes has decreased or stopped in favor of a more constant flux of lava from the vent.
Authorities carried out aerial surveys to check if hikers were trapped in the now cut-off areas, and later decided to temporarily close access to the eruption site.
