NaplesNaples (ˈneɪpəlz ; Napoli ˈnaːpoli; Napule ˈnɑːpələ) is the regional capital of Campania and the third-largest city of Italy, after Rome and Milan, with a population of 909,048 within the city's administrative limits as of 2022. Its province-level municipality is the third-most populous metropolitan city in Italy with a population of 3,115,320 residents, and its metropolitan area stretches beyond the boundaries of the city wall for approximately 20 miles.
IschiaIschia (ˈɪskiə , ˈiskja) is an Italian island in the Tyrrhenian Sea. It lies at the northern end of the Gulf of Naples, about from Naples. It is the largest of the Phlegrean Islands. Roughly trapezoidal in shape, it measures approximately east to west and north to south and has about of coastline and a surface area of . It is volcanic and almost entirely mountainous; the highest peak is Mount Epomeo, at . The island is very densely populated, with 62,000 residents (more than 1,300 inhabitants per square km).
HerculaneumHerculaneum (hɜːrkjʊˈleɪniəm; Neapolitan and Ercolano) was an ancient Roman town, located in the modern-day comune of Ercolano, Campania, Italy. Herculaneum was buried under volcanic ash and pumice in the Eruption of Mount Vesuvius in 79 AD. Like the nearby city of Pompeii, Herculaneum is famous as one of the few ancient cities to be preserved nearly intact, as the ash that blanketed the town protected it against looting and the elements. Although less known than Pompeii today, it was the first and, for a long time, the only discovered Vesuvian city (in 1709).
StratovolcanoA stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity.
LavaLava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called lava. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.
NolaNola is a town and a municipality in the Metropolitan City of Naples, Campania, southern Italy. It lies on the plain between Mount Vesuvius and the Apennines. It is traditionally credited as the diocese that introduced bells to Christian worship. Nola-Croce del Papa Excavations at Nola-Croce del Papa have uncovered extensive evidence of a small village quickly abandoned at the time of the Avellino Eruption in the 17th century BC. This powerful eruption from Mount Vesuvius caused the inhabitants to leave behind a wide range of pottery and other artefacts.
LipariLipari (ˈliːpari; Lìpari) is a comune including six of seven islands of the Aeolian Islands (Lipari, Vulcano, Panarea, Stromboli, Filicudi and Alicudi) and it is located in the Tyrrhenian Sea off the northern coast of Sicily, southern Italy; it is administratively part of the Metropolitan City of Messina. Its population is 12,821, but during the May to September tourist season, the total population may reach up to 20,000. It is also the name of the biggest island in the archipelago, where the main urban area of the comune is located.
Types of volcanic eruptionsSeveral types of volcanic eruptions—during which lava, tephra (ash, lapilli, volcanic bombs, and volcanic blocks), and assorted gases are expelled from a volcanic vent or fissure—have been distinguished by volcanologists. These are often named after famous volcanoes where that type of behavior has been observed. Some volcanoes may exhibit only one characteristic type of eruption during a period of activity, while others may display an entire sequence of types all in one eruptive series.
Plinian eruptionPlinian eruptions or Vesuvian eruptions are volcanic eruptions marked by their similarity to the eruption of Mount Vesuvius in 79 AD, which destroyed the ancient Roman cities of Herculaneum and Pompeii. The eruption was described in a letter written by Pliny the Younger, after the death of his uncle Pliny the Elder. Plinian/Vesuvian eruptions are marked by columns of volcanic debris and hot gases ejected high into the stratosphere, the second layer of Earth's atmosphere.
SalernoSalerno (UKsæˈlɛərnoʊ, USsəˈ-,_sɑːˈ-,_səˈlɜːrnoʊ, saˈlɛrno; Salierno saˈljernə) is an ancient city and commune in Campania, southwestern Italy, and is the capital of the namesake province, being the second largest city in the region by number of inhabitants, after Naples. It is located on the Gulf of Salerno on the Tyrrhenian Sea. In recent history the city hosted Victor Emmanuel III, the King of Italy, who moved from Rome in 1943 after Italy negotiated a peace with the Allies in World War II, making Salerno the capital of the "Government of the South" (Regno del Sud) and therefore provisional government seat for six months.
