Marsili is a large undersea volcano in the Tyrrhenian Sea , about 175 kilometers (109 mi) south of Naples . The seamount is about 3,000 m (9,800 feet) tall; its peak and crater are about 450 m below the sea surface. Though it has not erupted in recorded history, volcanologists believe that Marsili is a relatively fragile-walled structure, made of low-density and unstable rocks, fed by the underlying shallow magma chamber . Volcanologists with the Italian National Institute of Geophysics and Volcanology (INGV) announced on March 29, 2010, that Marsili could erupt at any time, and might experience a catastrophic collapse that would suddenly release vast amounts of magma in an undersea eruption and landslide that could trigger destructive tsunamis on the Italian coast and nearby Mediterranean coastlines.

35-624: Marsili belongs to the Aeolian Islands volcanic arc . It is one of the largest volcanoes in Europe, with a length of 70 kilometres (43 mi) and a width of 30 kilometres (19 mi), larger than Mount Etna . It was discovered during the 1920s and named after Italian geologist Luigi Ferdinando Marsili . Extensive studies have been carried on only since 2005 as the Italian National Research Council started

70-464: A World Heritage Site for providing "an outstanding record of volcanic island-building and destruction, and ongoing volcanic phenomena". Status as a World Heritage Site was threatened by Italy's failure to close the pumice quarry as well as its failure to prevent the building of 4 new harbours. However, as of 2020 , it is still listed by UNESCO as a World Heritage site. Filicudi Filicudi ( Italian pronunciation: [filiˈkuːdi] )

105-462: A huge outdoor terrace, usually shaded by grape and flowering vines. In Homer 's epic poem, the Odyssey , Aeolus , son of Hippotes , was the divine keeper of the winds and king of the mythical, floating island of Aeolia. He kept the violent winds locked safely away inside the interior of his isle, releasing them only at the command of greatest gods to wreak devastation upon the world. The hero of

140-565: A list of the most dangerous submarine volcanoes of the Tyrrhenian Sea, along with Magnaghi , Vavilov , and Palinuro . As with Vavilov, Marsili is at risk of a major collapse from a single event. In addition, hydrogeological deep-water surveys show that there is geothermal activity on Marsili. Marsili has been studied since 2005 as a strategic project of the Italian National Research Council by means of

175-740: A rumour appeared in international newspapers that the Aeolian Islands had been "swallowed up by the sea" during a time of volcanic activity. While communication with the islands was interrupted for a time, they were not otherwise inconvenienced. During World War II , all of the Aeolian Islands were captured by the Allies in August 1943, during the invasion of Sicily . The islands were then extensively searched by archeologists Madeleine Cavalier and Luigi Bernabò Brea after World War II . The Aeolian Islands were listed by UNESCO in 2000 as

210-661: A sonar system and integrated monitoring networks for ocean observations. In February 2010, the research vessel Urania began a study on the submerged volcano. Considerable instability has been detected. A significantly large region of the Marsili summit is also made up of low-density rocks, strongly weakened by hydrothermal alteration phenomena; which could cause a large collapse event. Aeolian Islands The Aeolian Islands ( / iː ˈ oʊ l i ən / ee- OH -lee-ən ; Italian : Isole Eolie [ˈiːzole eˈɔːlje] ; Sicilian : Ìsuli Eoli ), sometimes referred to as

245-411: A vulcanology research program on the site. The volcano rises from a plateau of thin oceanic (or pseudo-oceanic) crust with a thickness of only 10 km, which forms its own sea basin . The basin crust is made of tholeiitic basalt which is most typical of inflated basins at the back of oceanic volcanic arcs. The Marsili basin appears to have formed very recently (2 million years) as a consequence of

280-427: Is Lipari (37.5 km  [14.5 sq mi]), followed by Salina (26.8 km  [10.3 sq mi]), Vulcano (21.2 km  [8.2 sq mi]), Stromboli (12.6 km  [4.9 sq mi]), Filicudi (9.5 km  [3.7 sq mi]) and Alicudi (5.2 km  [2.0 sq mi]). The smallest island, at 3.4 km (1.3 sq mi), is Panarea. The highest elevation of

315-577: Is one of seven islands that make up the Aeolian archipelago , situated 56 km (35 mi) northeast of the island of Sicily , Southern Italy . It is a frazione of the comune of Lipari . Its total area is 9.5 km (3.7 sq mi). There are several small villages on the island, which include Pecorini Mare and Valdichiesa. Filicudi's lands are capable of producing wine, olive oil , grain, and vegetables. In 1997, three-quarters, approximately 7 km (2.7 sq mi) of Filicudi

350-535: Is said around 9,000 of the 10,000 citizens of Lipari were captured and enslaved although a couple of more recent scholars have questioned this number arguing for a lower population at the time of Barbarossa. A number of citizens were ransomed in Messina and returned to the islands but most of those captured never returned. Only after the tragedy did the Spanish authorities turn their attention to Lipari and repopulate

385-635: Is similar in composition to other volcanoes in the Aeolian Arc. The magma of Marsili came from the Ionian subduction of the seafloor of the Tethys Ocean . The volcanic activity started less than 200,000 years ago. Traces of volcanic collapse have been found on the sides of other submarine volcanoes, which may have resulted from tsunamis along the Tyrrhenian coast of southern Italy. Marsili is on

420-603: The Byzantine Empire . According to a Christian legend, in 264 a coffin which contained the body of Bartholomew washed up on the beach of Lipari, with the result that Bartholomew was immediately elected the patron saint of the Aeolian Islands. In 836 the Aghlabids of Ziyadat Allah I of Ifriqiya sacked Lipari, massacred most of the population, enslaved the survivors and annexed the Liparian Islands into

455-930: The Carthaginians against Rome during the Punic Wars . Although the Battle of the Lipari Islands in 260 BC led to a Carthaginian victory, the Romans later sacked Lipari and their domination led to a period of poverty. At the fall of the Western Roman Empire , the Aeolian Islands came under the sway of the Visigoths , the Vandals and the Ostrogoths , followed by the domination of

490-641: The Emirate of Sicily . The Norman conquest of Sicily from the Emirate of Sicily in 1061 resulted in the annexation of the islands. Roger II of Sicily sent the Benedictine monks to Lipari , which gave rise to considerable development on the islands. A cathedral dedicated to Saint Bartholomew was built, as well as the Benedictine monastery in the castle. In 1208 Frederick II of Swabia acceded to

525-521: The Greeks . Roman and Byzantine remains can also be found on the island. By 1971, the island had 270 residents. Roughly one-third of them left, however, after 26 May of that year, when Italian police used Filicudi as a place of exile for 18 reputed leaders of the Italian Mafia who were awaiting trial for on charges of organized crime. By 31 May, the remaining residents left in protest, with

560-543: The Lipari Islands or Lipari group ( / ˈ l ɪ p ə r i / LIP -ə-ree , Italian: [ˈliːpari] ) after their largest island , are a volcanic archipelago in the Tyrrhenian Sea north of Sicily , said to be named after Aeolus , the mythical ruler of the winds. The islands' inhabitants are known as Aeolians (Italian: Eoliani ). The islands had a permanent population of 14,224 at

595-417: The 2011 census; the latest official estimate is 15,419 as of 1 January 2019. The Aeolian Islands are a popular tourist destination in the summer and attract up to 600,000 visitors annually. There are seven significant islands: Lipari , Vulcano , Salina , Stromboli , Filicudi , Alicudi and Panarea , and a set of minor islands and rocks. The Aeolian Islands are 30 to 80 kilometres (19 to 50 mi) off

630-583: The Aeolian Islands were occupied by the Ausones led by Liparus . Liparus was succeeded by Aeolus whose house, according to the Odyssey by Homer , gave hospitality to Odysseus . In 580 BC, Greeks exiled from Rhodes and Knidos landed at Lipari and began a period of Greek domination , which was known for acts of piracy against Etruscan and Phoenician shipping. There was production of vases and other ceramics . The islanders were allies of

665-421: The Aeolian Islands were visited by Archduke Ludwig Salvator of Austria —a friend of the islands and also a man with a profound knowledge of the archipelago. Between the years 1893–96 he published a work of eight volumes on the Aeolian Islands. In August 1888, the crater named Fossa on Vulcano erupted and caused many deaths in the sulphur mines . The eruptions continued for 19 months. On New Year's Day in 1909,

700-443: The Aeolian Islands, together with Ustica and a series of submarine volcanoes named Magnani, Vavilov, Marsili and Palinuro , as well as two that are unnamed. The present shape of the Aeolian Islands is the result of volcanic activity over a period of 260,000 years. There are two active volcanoes – Stromboli and Vulcano . Steaming fumaroles and thermal waters are on most of the islands. The volcanic activity has also left

735-663: The French fleet without resistance, and in return obtained various commercial and fiscal benefits. In the mid-15th century, Naples and Palermo united into the Kingdom of the Two Sicilies under the crown of Alfonso V of Aragon . On June 30, 1544, a fleet of 180 Ottoman vessels under the command of the corsair Hayreddin Barbarossa occupied Lipari and laid siege to the castle. The defenders surrendered. Historically, it

770-477: The Lipari Islands is Monte Fossa delle Felci  [ it ] on Salina, which reaches a height of 962 m (3,156 ft). The seven Aeolian Islands, covering an area of 1,600 km (620 sq mi), originated in the Tyrrhenian Basin , a great plain at the bottom of the Tyrrhenian Sea . Emissions of lava from depths of up to 3,600 m (11,800 ft) resulted in the formation of

805-474: The city with Sicilian, Calabrian and Spanish families. The city walls and houses were rebuilt and an Aeolian fleet was constructed which was able to successfully defend the Tyrrhenian Sea from the Ottomans. In 1693, an earthquake destroyed all the towns in eastern Sicily, causing around 60,000 deaths. After the population invoked the protection of Saint Bartholomew during prayers in the cathedral , there

840-534: The epic poem, Odysseus , on his travels to return home from Troy , visited Aiolos' isle and was entrusted with a bag containing all of the winds to ensure a safe voyage home. However, during the trip, the hero's companions opened the bag and the escaping winds carried their ship all the way back to Aiolos' shore. The first evidence of Sicilian migration was in Lipari ( Castellaro Vecchio culture  [ it ] ). The manufacture and commerce of obsidian objects

875-475: The growth of the volcanic arc, and Marsili could be the result of the thermal inflation of the thin crust at the center of the basin. The start of the volcano activity could date back as recently as 200,000 years ago. Evidence of lava flows on the mountain flanks was found. Evidence of catastrophic collapses of previous other undersea volcanoes in the same area was also found. Marsili is an active volcano, with numerous satellite volcanic systems. The magma of Marsili

910-619: The islands except Salina comprise the commune of Lipari within that province; Salina forms three separate communes: Malfa , Leni and Santa Marina Salina . Curbing urban development has been a key in preserving the Aeolian islands in a natural state. New buildings are severely restricted. Existing residences can be bought and restored but they must be constructed to resemble its whitewashed houses. Traditional houses consist of modular cubes constructed from indigenous building materials like stone, lava, pumice, and tufo. Almost all houses have

945-530: The islands with a very fertile soil that is beneficial in the growth of natural flora . Geologically the archipelago is defined as a volcanic arc . The origin of the Aeolian Islands is due to movement of the Earth's crust as a result of plate tectonics . The African continental shelf is in constant movement towards Europe . Its subduction underneath the Eurasian plate generates magma , which rises to

980-520: The north coast of Sicily in the Tyrrhenian Sea. Vulcano is located closest to the Sicilian coast. Lipari and Salina follow to the north, Filicudi and Alicudi to the west, and Panarea and Stromboli to the northeast. In addition to these seven inhabited islands, there are a number of smaller, uninhabited islands and rocky cliffs, such as Basiluzzo , Strombolicchio , Dattilo  [ it ] and Lisca Bianca  [ it ] . The largest island

1015-496: The remains of the ex-penitentiary in the castle. However, not long after, the castle was converted to accommodate anti-Fascist political prisoners in enforced exile. Liparians fraternised with these exiles until the Allies ' liberation. After the war, the same room that had housed the opponents of Fascism became the Aeolian Archaeological Museum  [ it ] . Towards the end of the 19th century,

1050-527: The sea. The modern name of "Filicudi" is a corruption of the ancient Greek name for the island, Phoenicusa (Phoenician island). The island, like the other Aeolian Islands , was settled since the Neolithic Age , around 3000 BCE. As evidenced by archaeological findings, the island was occupied by a new people during the Bronze Age . The island was uninhabited for many centuries until occupied by

1085-525: The surface to form the volcanoes . The "Aeolian Arc" extends for more than 140 km (87 mi). It is a section of a larger area of geological instability across the Mediterranean region, caused by the collision of Africa and Europe , which includes Sicily , Calabria , and Campania together with Greece and the Aegean islands . The islands form part of the Sicilian province of Messina . All

1120-635: The throne of the Kingdom of Sicily . The period of prosperity which followed, ended with the domination of the Angevins and the rebellion of the Sicilians which culminated in the revolt of the Sicilian Vespers . The Aeolians however, remained loyal to Charles of Anjou , and commercial links were established with Naples , the capital of the Angevin kingdom. In 1337 Lipari opened its gates to

1155-632: Was highly developed until the introduction of metals . During the Bronze Age , the Aeolians prospered by means of maritime commerce in an area which extended from Mycenae to the British Isles , from where tin was imported. Villages on the Aeolian islands flourished on Capo Graziano (Filicudi), Castello (Lipari), Serro dei Cianfi (Salina), Capo Milazzese (Panarea), and Portella (Salina). All these settlements were destroyed by new Italic invasions in 1250 BC. According to Diodorus Siculus ,

1190-589: Was not a single victim on the Aeolian Islands. The economic conditions of the islands improved greatly during the 17th century with agricultural progress ( malvasia grapes), capers , and a variety of fruit, vegetables and fishing). With the Bourbons came the introduction of criminal and political prisoners to the islands. In 1916, the penal colony was closed, but the Fascist regime unsuccessfully tried to reopen it in 1926. The island population reacted by pulling down

1225-430: Was turned into a Natural Reserve. The highest point is Monte Fossa Felci at 774 m (2,539 ft). Other points include Monte Montagnola at 349 m (1,145 ft) and Monte Terrione at 278 m (912 ft). At Capo Graziano are the remains of a Bronze Age village dating back to the second millennium BCE. Off the coast, the volcanic finger-like rock of La Canna rises about 74 metres (243 ft) above
