Stromboli names a small island located in the Tyrrhenian Sea. This sits just off the northern coast of Sicily, in Europe. The island of Stromboli contains one of the three active volcanoes in Italy.
It also forms one of the eight islands comprising the Aeolian Islands, an active volcanic arc north of Sicily. The name of the island derives from Ancient Greek and means swollen form.
The island’s current population numbers fewer than 850 individuals. The volcano erupted with moderate violence numerous times in the past. Additionally, it continues to be constantly active with minor eruptions.
These often appear visible from many points on the island and from the surrounding sea. This gave rise to the island’s nickname: Lighthouse of the Mediterranean.
The last major eruption of Stromboli occurred on 13 April 2009. The volcano stands 3,034 ft (926 m) above sea level, but below the waves, the actual base rises roughly 8,860 ft (2,700 m) above the ocean floor.
A total of three active craters sit at the peak. Yet another significant geological feature of Stromboli bears the name of Sciara del Fuoco. This names a large horseshoe-shaped depression created over the past 13,000 years.
It formed due to several collapses on the northwestern side of the cone. About 1.2 mi (2 km) to the northeast lies the remnant of the original volcano.
Stromboli Activity Patterns
Stromboli has been in almost continuous eruption for the past 2,000 years. Eruptions in the summit craters have maintained a fairly regular pattern. These include mild to moderate eruptions of incandescent volcanic bombs.
The intervals of these eruptive events range from every few minutes to every few hours. Eruptions from the craters at the summit typically result in a few short bursts. They are, however, highly energetic in nature.
Eruptions also average a height of nearly 650 ft. (200 m). They generally include ash, incandescent lava fragments, and blocks of stone.
The activity type of Stromboli remains almost exclusively explosive. However, lava flows do occur periodically when volcanic activity is high.
