A complex volcano, also called a compound volcano or a volcanic complex, is a mixed landform consisting of related volcanic centers and their associated lava flows and pyroclastic rock. They may form due to changes in eruptive habit or in the location of the principal vent area on a particular volcano. [2]
Nevado Ojos del Salado is a dormant complex volcano in the Andes on the Argentina – Chile border. It is the highest volcano on Earth and the highest peak in Chile. The upper reaches of Ojos del Salado consist of several overlapping lava domes, lava flows and volcanic craters, with sparse ice cover. The complex extends over an area of 70–160 ...

Vesuvius has a long historic and literary tradition. It was considered a divinity of the Genius type at the time of the eruption of AD 79: it appears under the inscribed name Vesuvius as a serpent in the decorative frescos of many lararia, or household shrines, surviving from Pompeii. An inscription from Capua to IOVI VESVVIO indicates that he was ...
Vesuvius was a name of the volcano in frequent use by the authors of the late Roman Republic and the early Roman Empire. Its collateral forms were Vesaevus, Vesevus, Vesbius and Vesvius. Writers in ancient Greek used Οὐεσούιον or Οὐεσούιος. Many scholars since then have offered an etymology. Given that peoples of varying ethnicity and language occu...
Vesuvius is a "humpbacked" peak, consisting of a large cone (Gran Cono) partially encircled by the steep rim of a summit caldera caused by the collapse of an earlier (and originally much higher) structure called Mount Somma. The Gran Cono was produced during the A.D. 79 eruption. For this reason, the volcano is also called Somma-Vesuvius or Somma-V...
Vesuvius is a stratovolcano and was formed as a result of the collision of two tectonic plates, the African and the Eurasian. The former was subducted at a convergent boundary beneath the latter, deeper into the earth. As the water-saturated sediments of the African oceanic plate were pushed to hotter depths inside the planet, the water boiled off ...
Mount Vesuvius has erupted many times. Numerous others preceded the eruption in AD 79 in prehistory, including at least three significantly larger; an example is the Avellino eruption around 1800 BC, which engulfed several Bronze Age settlements. Since AD 79, the volcano has also erupted repeatedly, in 172, 203, 222, possibly in 303, 379, 472, 512,...
The area around Vesuvius was officially declared a national park on 5 June 1995.The summit of Vesuvius is open to visitors, and there is a small network of paths around the volcano that are maintained by the park authorities on weekends. There is access by road to within 200 metres (660 ft) of the summit (measured vertically), but after that, acces...
Mount Vesuvius' first funicular— a type of vertical transport that uses two opposing, interconnected, rail-guided passenger cars always moving in concert — opened in 1880, subsequently destroyed by the March 1944 eruption. "Funiculì, Funiculà", a Neapolitan languagesong, was written to commemorate the opening of the first funicular on Mount Vesuviu...

Apr 29, 2024 · About 1,900 volcanoes on Earth are considered active, meaning they show some level of occasional activity and are likely to erupt again. Many others are dormant volcanoes, showing no current signs of exploding but likely to become active at some point in the future. Others are considered extinct. Volcanoes are incredibly powerful agents of change.
Composite cones, shield volcanoes, cinder cones and supervolcanoes are some of the types of volcanoes formed. Composite cones are tall, cone shaped volcanoes that produce explosive eruptions. Shield volcanoes form very large, gently sloped volcanoes with a wide base. Cinder cones are the smallest volcanic landform.
