Stromboli (Eolian Islands, Italy): (18 Jun) Another short-lived lava flow on the Sciara del Fuoco occurred in the evening of Thursday, 17 June. Starting from 21:10 local time and accompanied by a moderate rockfall event on the slope, lava over-spilled from the northern crater area and formed a flow on the upper Sciara about 200 m long.
The lava flow generated near-continuous smaller rockfalls and dust clouds on the slope. It only lasted a few hours and by around 4:30 am the next morning had ceased while the volcano’s activity had returned to normal levels (spattering, intermittent strombolian explosions at the summit vents).
Etna (Sicily, Italy): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Toulouse warned about a volcanic ash plume that rose up to estimated 20000 ft (6100 m) altitude or flight level 200 and is moving at 35 kts in S direction.
The full report is as follows: ERUPTION AT 20210619/1820Z WITH ASH EMISSION OBS VA DTG:19/1900Z to 20000 ft (6100 m)
…18 Jun:
Only about a day and a half since the paroxysm in the early afternoon of 16 June, another one occurred early on 18 June from the New SE crater:
After a quiet interval of approx. 30 hours, weak strombolian activity started again to appear at the New SE crater after midnight 17-18 June, then quickly intensified and produced sustained lava fountains several hundred meters tall between 1.20 – 2.10 am (local time). Another lava flow traveled from the southern crater rim towards the SW.
The similarity of the latest events and their quite regular occurrence at similar but decreasing trend suggest that the volcano again is in a phase of rhythmic behavior of short-lived, but violent lava fountaining episodes following each other at similar intervals of currently around 36-40 hours. A next event like this might well occur during the afternoon of Sat, 19 June, if the pattern continues to repeat.
Suwanose-jima (Ryukyu Islands): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: EXPLODED AT 20210619/1858Z FL040 EXTD SE OBS VA DTG:19/1850Z
…18 Jun:
The explosive eruption of the volcano continues.
The volcano produced near-constant moderate vulcanian-type explosions that reached up to approximately 6,000 ft-8,000 ft (1,800 m-2,500 m) altitude and dispersed S-SW. Explosions generated pyroclastic bombs and blocks ejected 500 meters away from the crater.
