The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
Climbing Stromboli volcano: Stromboli provides one of the most remarkable opportunities to watch volcanic eruptions from close: a natural ridge located 150 m above the active vents. A classic and all-time favorite tour by anyone interested in seeing active volcanoes!
Stromboli, a small island north of Sicily, is one of the most active volcanoes in the world and famous for its normally small, but regular explosions throwing out glowing lava from several vents inside its summit crater. This activity has been going on for at least 2000 years, as long as there is written memory of the activity, which Stromboli lended its name to, the so-called strombolian activity.
Another lava overflow from the NE vent occurred this morning, starting around 10:00 local time. It followed a phase of increased activity from the summit vents. ...more
Being issued more towards the east from the vent itself, it took a through a gap between the N1 and N2 vents and traveled on the upper Sciara a bit more to the north compared to the previous lava flows. By the afternoon, it had already more or less stopped. Many rockfalls have been occurring on the Sciara during the whole day.

Strombolian eruption from Stromboli's NE vent yesterday
Since 11 July, the volcano has been calmer compared to the previous weeks. No new lava overflows on the Sciara del Fuoco have occurred since 10 July, but who knows if a next surge of magma is already underway soon?
Two new lava (over-)flows occurred from the NE vent last evening and this morning. Similar as during the previous episodes, the flows were the result of surges in magma supply, quickly descended the upper part of the Sciara del Fuoco, and then stopped: ...more
It almost appears that these peaks of activity are following each other at intervals of 2-3 days.

After a weekend with comparably low activity and no lava overflows, a new surge of lava effusion has started and a small lava overflow is again active on the upper Sciara del Fuoco. The surge of the magma caused a partial collapse of the NE hornito (N2 vent) at 05:35 UTC, producing an impressive avalanche resembling a pyroclastic flow. ...more
Tremor is elevated as well.

Activity decreased again last night, and the latest lava flow (almost) stopped. Very weak lava effusion continues from the NE hornito vent ("N2" in INGV Catania's nomenclature) at the time of this update.

A second, powerful surge of lava, again from the NE vent, started short time ago and has been feeding a new lava flow that quickly descended several 100 meters the upper Sciara del Fuoco (s. video below). ...more
The first flow from earlier today, that had started at around 04:50 local time, had in the meanwhile decreased and eventually stopped in the hours after 12:00. Tremor has risen again as well, and a smaller lava overflow from the NE hornito is visible inside the crater terrace. Strombolian explosions continue to be intense and frequent at the summit vents.

The activity at the volcano remains at similar elevated levels with strong spattering, intense strombolian explosions and lava overflows. ...more
Today, both the intra-crater lava flow and the one overflowing onto the upper Sciara del Fuoco from the NE hornito vent remain intermittently active. The following time-lapse video shows the latter seen from INGV's thermal webcam on the Sciara del Fuoco:

Activity at the volcano increased further and produced several lava overflows both inside the crater and on the upper Sciara del Fuoco. At the moment, the latter one is still active and has a length of approx. 200 m. ...more
Following intense phases of continuous spattering (or small lava fountaining) from the central and other vents, accompanied by increasing tremor, a first intra-crater lava flow started around 08:30 local time from the NE hornito (S2). Shortly after, starting from 11:18 an effusive vent starts to open up on the outer northwestern slope of the crater terrace, some ten meters beneath the NW vent complex (vent S3), and issue a lava flow directly onto the Sciara.
The first 3 lava flows yesterday: the first (below) as intracrater lava flow from S2 (northeast hornito) vent, the second flow as short-lived flow from a new vent on the outer NW slope beneath the crater rim (top r), and the third flow, again an intracrater flow from S2 in the evening.

Strong eruption from Stromboli's NE vent and a weak lava overflow
A lava overflow erupted from the NW hornito on Sunday and traveled approx. 200 m down the Sciara del Fuoco. This followed a particularly intense phase of activity at this vent, marked by frequent and strong explosions and continuous spattering. ...more
Smaller, short-lived overflows have occurred from the same vent since, and activity remains high, with many explosions from several vents:

Two simultaneous strong explosions from the NW (l) and NE (r) vents at Stromboli on 9 June
The activity at the volcano has strongly increased since about 2 weeks ago. Our group tour visited Stromboli during 8-11 June and observed at least 14 active glowing vents. It appears that the magma level has once again risen to very near the surface of the crater terrace. ...more
About half of them were showing constant or, some, intermittent weak to strong spattering: in particular, the twin vents of the central crater, two vents in the western crater, the NW hornito, as well as, intermittently, the hornito at the northwestern rim of the NE crater. Typical strombolian explosions, some quite strong with ejection heights to 200-300 m, occurred at intervals of 5-10 minutes mainly from the westernmost twin vents, the NW hornito, the large NE vent, and occasionally also from the central crater. The NW hornito often produced a 3-5 meters tall pale purple flame-like gas jet that usually preceded candle-like eruptions accompanied by very loud jet-engine noises. [less]
Recently discovered dinosaur footprints in volcanic ash layers on a remote island volcano challenge the widely accepted theory that dinosaurs got extinct 65 million years ago. Some of them might have survived for much longer.
Tours to active volcanoes: Watching a volcanic eruption is one of the most impressive natural displays. We have a wide selection of tours to active volcanoes worldwide at different activity and difficulty levels.
Top 20 quakes in 2016: Several magnitude 7 quakes occurred in 2016 (but none above M8): Papua New Guinea, NZ, Ecuador, Solomon Islands, Sumatra, Chile, Alaska and others - nearly all major earthquakes were located near active subduction zones.
