STROMBOLI, THE LIGHTHOUSE OF THE MEDITERRANEAN

Stromboli, Aeolian Islands
The Grandma loves volcanoes. Everybody knows it. In Stromboli, one of the eight Aeolian Islands in Sicily, there is one of the most active volcanoes of the planet, the Stromboli that gives its name to the Island.

This afternoon, a great eruption has surprised the inhabitants and the tourists in Stromboli. It has been a paroxysmal eruption, not the normal and frequent eruptions that remembers, daily, that this volcano is active and can roar in every moment causing the worst damages that we can imagine.

The Grandma has studied a new lesson of her Ms. Excel course.


Stromboli, from Ancient Greek Στρογγύλη, is a small island in the Tyrrhenian Sea, off the north coast of Sicily, containing one of the three active volcanoes in Italy. It is one of the eight Aeolian Islands, a volcanic arc north of Sicily.

This name is derived from the Ancient Greek name Strongúlē, which was derived from στρογγύλος, round, after the volcano's round, conical appearance when seen from a distance. The island's population is about 500. The volcano has erupted many times and is constantly active with minor eruptions, often visible from many points on the island and from the surrounding sea, giving rise to the island's nickname Lighthouse of the Mediterranean.

Stromboli's eruption, July 3 2019
Stromboli stands 926 m above sea level, and over 2,700 m on average above the sea floor. There are three active craters at the peak. A significant geological feature of the volcano is the Sciara del Fuoco, stream of fire, a big horseshoe-shaped depression generated in the last 13,000 years by several collapses on the northwestern side of the cone. Approximately 2 km to the northeast lies Strombolicchio, the volcanic plug remnant of the original volcano.

Mount Stromboli has been in almost continuous eruption for the past 2,000 years. A pattern of eruption is maintained in which explosions occur at the summit craters, with mild to moderate eruptions of incandescent volcanic bombs, at intervals ranging from minutes to hours.

This Strombolian eruption, as it is known, is also observed at other volcanoes worldwide. Eruptions from the summit craters typically result in a few short, mild, but energetic bursts, ranging up to a few hundred meters in height, containing ash, incandescent lava fragments and stone blocks.

Stromboli's activity is almost exclusively explosive, but lava flows do occur at times when volcanic activity is high: an effusive eruption occurred in 2002, the first in 17 years, and again in 2003, 2007, and 2013–14. Volcanic gas emissions from this volcano are measured by a multi-component gas analyzer system, which detects pre-eruptive degassing of rising magma, improving prediction of volcanic activity.

Stromboli's most recent eruption took place today, 3 July 2019, where two major explosive events occurred at around 4:46 PM local time, alongside 20 additional minor explosive events identified by Italy's National Institute of Geophysics and Volcanology. A hiker in the vicinity of the volcano's summit was killed after being struck by flying debris when the eruption began.

The two villages San Bartolo and San Vincenzo lie in the northeast while the smaller village Ginostra lies in the southwest. Administratively, they are one of the frazione of Lipari, Messina.

In the early 1900s a few thousand people inhabited the island, but after several emigrations the population numbered a few hundred by the mid-1950s.

My ancestors are on Stromboli, while yours, dear reader,
came from another island, another village or another place.
What we share is a past that is awaiting our voyage of discovery.
