The eruption at Etna continues with strombolian activity from two vents in the upper part of the May 13 fissure and the emission of a lava flow into Valle del Bove.

The eruption at Etna volcano continues and has even increased slightly, according to observations during our recent tour (7-15 June) and informataion from INGV Catania. Two vents on the May13 fissure continue to display weak to moderate strombolian activity and feed an active lava flow into Valle del Bove, with fronts reaching 1900 m elevation, NE of the Monti Centenari.

As INGV Catania reports, the mild strombolian activity and small effusion of lava from the 13 May eruptive fissure continue.

Over the last days, the activity at the May 13 eruptive fissure has been slighlty increasing. Charles Rivière reports lava fountaining took place at the upper vents of the fissure during the night of 4-5 June.

Strombolian explosion from a vent at 2800m a.s.l. on the May 13 eruptive fissure (Etna volcano)

The eruption at Etna that had started spectacularly on May 13, is still continuing, although lava emission had drastically decreased shortly after the onset of the eruption.
Some field observations made by our team during May 23 and 24: one of the several vents aligned on the impressive fissure below the E side of SE crater was still spattering and erupting small strombolian fountains at irregular intervals of 30-60 minutes. Another two vents just above it were emitting ash, dark fragments and occasionally glowing bombs at less infrquent intervals. The active vent at times shows powerful explosions throwing bombs to several hundred meters height. One of these was witnessed at (too) close range on May 25 in the evening, but it was possible to shelter from falling blocks under a huge block thrown out at the opening of the fissure. The lava flow continues weakly, with a barely incandescent front of tumbling, glowing blocks at the active front on the steep wall of the Valle del Bove.

Our team member Marco Fulle who just visited Stromboli volcano with a small group reports strong, candle-like eruptions from the NE vent in the central crater of Stromboli volcano, that reach 300 m height. A similar eruption style had been present during much of 2006 and sometimes in 2007.

Although further decreasing, ash and lava emissions are still continuing from the new fissure vents at the E base of SE cone.

Lava and ash emissions continue although at very low levels. The violent fissure eruption that started on May 13 from an originally 600 m long east-trending fissure parting from the NE base of the SE crater at around 2900 m elevation decreased surprisingly quickly in intensity. It seems to be coming to a soon end, although a weak emission of lava continues at present.
On the other hand, it seems likely that this extremely short eruption is only a precursor to another one following in the near future, in particular when one takes the intense recent events of ground fracturing and seismic activity into account.
On May 14, 5 of the originally ca. 15 active vents on the originally ca. 600 m long fissure (personal observations by Rosario) were still active. On May 15, only 3 of them and on May 16-17, spattering and lava emission were already very low. On May 17, some powerful ash emissions, perhaps related to internal collapse events were observed from the pit crater at the E base of the ...

From field observations by Rosario, the beginning of a large new eruption at Etna is confirmed. Following the intense tremor, a fissure has opened NE of the SE crater, about 800m long, and erupting from about 15 vents with spectacular bubbles and hawaiian lava fountains. The lava is very fluid and forms impressive flows into the Valle del Bove.
Ash fall has covered the area of Randazzo by about 1 cm. Still as a result of the brief violent precursor eruption from SE crater on May 10, the airport of Catania is closed. Access to the moutain has been closed at 1200 m on all roads. The bad weather at present does not allow detailed information. We are on our way to Etna to report more in the following days.

Our VolcanoDiscovery team member Marco Fulle reports a new, strong earthquake and the opening of a fissure in a pine wood at the Linguaglossa area.
 
Probably new, strong activities will taking place soon...
 
Catania CTA airport remains closed because of the ash emissions of Etna volcano.

The new eruption phase of Etna volcano shows high seismic activity and ash clouds caused the airport of Catania to be closed. Our team member Marco Fulle is reporting high seismic activity that may cause a new fisure to be opened at Etna volcano.

Our VolcanoDiscovery Team members Marco Fulle and Rossario Basile report new paroximal eruptions at the SEC area of Etna volcano and a lava flow into the Valle del Bove. Because of bad weather conditions no more details can be reported yet.

As observed during our recent tour to Etna and the Eolian Islands, mild strombolian activity, with small exploisions every 10-20 minutes, is present at the vent located at the lower E flank of the SE crater of Etna.

Etna's SE crater, the youngest and in recent years most active of its 4 summit vents, is increasing its activity. 
Since the ash emissions started in mid August, weak strombolian activity has been increasing gradually. The first incanescent ejecta were observed by INGV on 21 August. Over the past week, strombolian activity has become more and more common. On 31 August, an overflight confirmed that a new cinder cone is now growing within the depression in the eastern flank of the SEC.

Etna is back erupting. Since 15 August 2007, the SE crater has been showing weak explosive activity from the vent in the collapse pit on the E falnk of the SE cone. The activity consits mainly of deep-seated strombolian explosions occurring at irregular intervals of several minutes or more, producing dark to brown ash plumes with some fresh material.

As our colleague Andrea Ercolani reports from Stromboli, access to the summit area of Stromboli has been reopened for guided tours under certain restrictions. In brief, small groups accompanied with authorized guides can now reach the ridge east of the crater terrace between 750 and around 850 m elevation where a few shelters are located, but the maximum stay is now limited to 30 minutes. Access to the Pizzo summit itself is limited to the time necessary for passing along the trail.

As Andrea Ercolani reports from Stromboli, the "normal" strombolian activity seems to be returning to the summit craters since early July.
After the effusive eruption which ended on 4th of April this year and a powerful vent-clearing explosion on 15 March, there have been deep-seated explosions ejecting black ash clouds since May. In July, these have beomce more regular and it seems that the magma level inside the vents has been rising and there could soon be visible lava ejections again.
Access to the summit is still restricted and visitors may only climb up to 400m elevation accompanied by an authorized mountain guide, but it is being discussed wether new rules to allow access to the summit will be established. This will be communicated here as soon as it happens.
