Mount Vesuvius violently spewed forth a cloud of super-heated tephra and gases to a height of 33 km (21 mi), ejecting molten rock, pulverized pumice and hot ash at 1.5 million tons per second, ultimately releasing 100,000 times the thermal energy of the atomic bombings of Hiroshima and Nagasaki.
Mount Vesuvius (/ v ɪ ˈ s uː v i ə s / viss-OO-vee-əs) [a] is a somma–stratovolcano located on the Gulf of Naples in Campania, Italy, about 9 km (5.6 mi) east of Naples and a short distance from the shore. It is one of several volcanoes forming the Campanian volcanic arc.
The general shape of the ash and cinder fall (see w:en:pyroclast) is shown by the dark area to the southeast of Mt Vesuvius. (P.S. It seems strange to show the modern day English names for the two bodies of water - I am open to suggestions). This map shows lines and uses the Mercator projection (although that is not important on a map of this ...
The Mercato eruption (Pomici di Mercato) of Mount Vesuvius was a Plinian eruption that occurred around 8,010 ± 40 14C yr BP (8,890 ± 90 cal yr BP). [3] The Global Volcanism Program claims that the eruption had a Volcanic Explosivity Index (VEI) of 5, [1] while Zanella et al. (2014) estimate it had a VEI of 6. [2]
As the area around Mount Vesuvius is highly urbanized, it became necessary to develop evacuation plans to be applied when the signs of a forthcoming eruption appear. [3] A danger zone around the volcano was first identified in 2001 by the Italian Protezione Civile ; its boundaries were then redefined in 2013 following new studies on the ...
The beach at the Herculaneum archaeological park is thought to be the site where more than 300 men tried in vain to save themselves while awaiting rescue by Pliny the Elder.
Mount Emmons, Mount Hague, and Double Crater are post-caldera cones. [6] The topography of the Basin and Range Province is a result of crustal extension within this part of the North American Plate (rifting of the North American craton or Laurentia from Western North America; e.g. Gulf of California, Rio Grande rift, Oregon-Idaho graben).
Stabiae (Latin: [ˈstabɪ.ae̯]) was an ancient city situated near the modern town of Castellammare di Stabia and approximately 4.5 km southwest of Pompeii.Like Pompeii, and being only 16 km (9.9 mi) from Mount Vesuvius, it was largely buried by tephra ash in the 79 AD eruption of Mount Vesuvius, in this case at a shallower depth of up to 5 m.
