When observed during 3-6 June, the volcano was at normal levels of activity which had not changed significantly since our last visit 2 weeks ago. On the crater terrace, about 7 active vents were present, with eruptions every about 15-20 minutes: the two vents in the NW crater sometimes erupted simultaneously, one with low ejections of blocks, scoria and ash, the other with loud turbine-like jets of gas and lava fragments that often reached about 250 m height. The hornito at the NW crater rim was not seen erupting. ...more [read all]

Activity continues at moderately elevated levels. Spectacular explosions especially from the NE crater can often be seen on the webcam as well.

Explosive activity at Stromboli is currently at normal to moderately high levels, but the magma column has obviously dropped considerably compared to previous weeks, as there are no longer lava overflows. We observed the volcano during the past days and found a total of 8 active vents in the crater terrace, out of which 4 were showing their typical different strombolian activity: ...more [read all]

Over the past days, Stromboli has returned to normal levels of activity with frequent, mostly small to medium-sized explosions and low to medium tremor. Small lava overflows and frequent rockfalls still occur.

Activity has remained generally elevated and seems to have increased yesterday. Current seismic recordings show strong explosion signals and an increase in tremor. A small lava overflow is currently visible from the NE crater.

Lava continues to intermittently flow over and out of vents at the rim and the base of the NE crater. Yesterday, the active flow front had reached about half way down the Sciara, local guides reported. ...more [read all]

After decreasing a bit yesterday, the overflow of lava from the NE vents has gained in strength this morning again, accompanied by constant rockfalls, relatively strong explosions and higher tremor.

Spattering and lava effusion have increased from the NE hornito, feeding a new relatively large sustained lava flow on the Sciara del Fuoco.

Activity has decreased a bit yesterday, but strong explosions and small lava overflows from the NE crater rim and a vent at the outer flank continued, accompanied by frequent rockfalls on the Sciara. At the moment, activity seems to be increasing again. [read all]

An increase in activity occurred yesterday. Lava started to effuse from one or two vents at the base of and on the outer flank below the NE hornito. It is currently extending on the upper part of the Sciara and produces strong rockfalls that reach the sea. ...more [read all]

Activity remains elevated, with magma filling the NE crater to the rim and sometimes relatively strong explosions. No significant new overflows have occurred since the last update.

The small lava flow issuing from the breached NE crater continues, but has not progressed much. Frequent glowing rockfalls descend the Sciara del Fuoco.

Magma stands high inside the conduits. A small overflow is occurring from the NE crater. The lava flow reaches about 100 meters length at the moment. Tremor and explosion signals are moderate to elevated. [read all]

Activity remains elevated, but the new lava flow is no longer much alimented at the moment. ...more

The lava flow continues to be alimented, but effusion rate has apparently dropped and only the upper portion of the flow seems currently active. The seismic signal shows strong eruption tremor and continuous rockfall signals.

The activity continued throughout the night and the lava flow has reached the sea at the base of the Sciara del Fuoco. At the moment, the new flow has decreased but remains weakly active and tremor elevated.

The new lava flow is well alimented and has reached several hundred meters down on the Sciara del Fuoco. Explosive activity continues as well.

A new larger lava flow from the NE vent has started this afternoon to descend the Sciara del Fuoco, accompanied by glowing rockfalls and strong tremor. The eruption was preceded by very large strombolian explosions during the morning. [read all]

A late addition - photos of the lava overspills and lava flows on Sciara del Fuoco during the first half of January.

Activity has remained more or less unchanged. Explosions, sometimes strong continue from several vents,and small amounts of viscous lava overspills the rims of the NE crater.

Activity remains elevated. Lava continues to overspill from the lips of the NE crater, showing that the magma column stands high inside the conduit. Frequent strombolian explosions are reaching heights of 2-300 m and the tremor signal is strong again today.

Yesterday evening's lava flow has once again beeen very short-lived. Activity (effusion rate) sharply dropped late in the evening and today, only very small amounts of lava are still overspilling from the NE crater rim. Tremor and rockfall signals are much weaker as well.

A strong increase of activity occurred this afternoon. A relatively large, sustained lava flow has started to erupt from the breached NE cone and descend the Sciara del Fuoco. The process is accompanied by ongoing strong strombolian eruptions, mainly from the same NE vent, and strong continuous tremor. ...more [read all]

No significant changes have occurred recently. The seismic signal shows medium tremor levels with phases of medium to high values, and there are frequent (about 10 per hour), sometimes quite powerful strombolian explosions from the various active vents. Small amounts of lava sometimes overspill from the NE vent.

Seismic activity remains elevated and accompanies strong explosions, mainly from the NE vent. No recent lava overflows occurred.

Tremor and explosion signals have further increased today, but no significant new lava overflows have occurred.

The NE crater continues to produce spectacular and relatively large explosions of bursting lava bubbles. Tremor as well is elevated.
