Italy Volcano Stromboli Has Large Eruption

Italy's volcanic island of Stromboli put on quite a show today, as a large plume of gas and ash reached up to 3km above the summit. No damage was reported. Stromboli is one of the most active volcanoes in Italy, second probably only to Mt. Etna which is near constantly active. This eruption type is uncharacteristic of Stromboli, which is known for "Strombolian Eruptions", which, obviously, is the source of the term. Strobolian eruptions are characterized as small to medium sized eruptions in which red hot ejecta is discharged from the summit of the volcano, typically making quite a spectacular, and relatively safe show.

A statement on Facebook from INVOLCAN (which also monitors some other European and North African volcanoes) said (translated from Spanish)

"LAST minute: Strong explosions in one of the most famous volcanoes of the planet, Stromboli. There is no damage, although the column reached 3 km above the volcano, very unusual thing in this well-known Italian volcano."

Stromboli is characterized by the Smithsonian USGS:

"Spectacular incandescent nighttime explosions at Stromboli volcano have long attracted visitors to the "Lighthouse of the Mediterranean." Stromboli, the NE-most of the Aeolian Islands, has lent its name to the frequent mild explosive activity that has characterized its eruptions throughout much of historical time. The small, 924-m-high island of Stromboli is the emergent summit of a volcano that grew in two main eruptive cycles, the last of which formed the western portion of the island. The Neostromboli eruptive period from about 13,000 to 5000 years ago was followed by formation of the modern Stromboli edifice. The active summit vents are located at the head of the Sciara del Fuoco, a prominent horseshoe-shaped scarp formed about 5000 years ago as a result of the most recent of a series of slope failures that extend to below sea level. The modern volcano has been constructed within this scarp, which funnels pyroclastic ejecta and lava flows to the NW. Essentially continuous mild strombolian explosions, sometimes accompanied by lava flows, have been recorded at Stromboli for more than a millennium."
