Mount Vesuvius is a volcano located in southern Italy, near the bay of Naples and the city of Naples. It is the only active volcano on the European mainland. Vesuvius rises to a height of 1277 m (4190 ft). Vesuvio (Vesuvius) is probably the most famous volcano on earth, and is one of the most dangerous.
Mount Vesuvius is a strato-volcano consisting of a volcanic cone (Gran Cono) that was built within a summit caldera (Mount Somma). The Somma-Vesuvius complex has formed over the last 25,000 years by means of a sequence of eruptions of variable explosiveness, ranging from the quiet lava outpourings that characterized much of the latest activity (for example from 1881 to 1899 and from 1926 to 1930) to the explosive Plinian eruptions, including the one that destroyed Pompeii and killed thousands of people in 79 A.D. At least seven Plinian eruptions have been identified in
the eruptive history of Somma-Vesuvius (1). Each was preceded by a long period of stillness, which in the case of the 79 A.D. eruption lasted about 700 years. These eruptions were fed by viscous water-rich phonotitic to tephritic phonolitic magmas that appear to have differentiated in shallow crustal conditions. They are believed to have slowly filled a reservoir where differentiation was driven by compositional convection. A minimum depth of about 3 km was inferred for the top of the magmatic reservoir from
mineral equilibria of metamorphic carbonate ejecta (2). Fluid inclusions ([CO.sub.2] and [H.sub.2]O-[CO.sub.2]) in clinopyroxenes from cumulate and nodules indicate a trapping pressure of 1.0 to 2.5 kbar at about 1200 [degrees]C, suggesting that these minerals crystallized at depths of 4 to 10 km (3). The differentiated magma fraction was about 30% of the total magma in the reservoir, and a volume of about 2 to 3 [km.sup.3] was
inferred for the reservoir (4). The magma ascent to the surface occurred through a conduit of possibly 70 to 100 m in diameter (5). A thermal model predicts that such a reservoir should contain a core of partially molten magma (6) that can be detected by high-resolution seismic tomography.
The earliest outcropping volcanic deposits date back to about 25,000 years ago. The lavas observed at a -1125 m bore-hole are about 0,3-0,5 million years old. It is known for the first eruption of which an eyewitness account is preserved, in 79 AD. Geologically, Vesuvio is unique for its unusual versatility. Its activity ranging from Hawaiian-style release of liquid lava, fountaining and lava lakes, over Strombolian and Vulcanian activity to violently explosive, plinian events that produce pyroclastic flows and surges.

Sebastian Pether’s piece of work called The Eruption of Vesuvius (1835) combines the silver watery reflection of the moon with the hot red molten lava that is flowing down its mountainsides. Though during Pether’s generation he wasn’t the only one to paint the well-known Mount Vesuvius, Joseph Wright of Derby also painted 30 paintings of the volcano. This art piece is currently located at the Nelson-Atkins Museum of Art. The piece is oil media on panel that is framed with a beautifully designed border, where it is hanging on a wall in the one of the rooms, with a one-dimension view. The quality of the piece owes itself to the color and lighting, which captures your immediate attention and guides the viewer through the piece.

On the afternoon of 24th August 79 AD, a volcano called Mt. Vesuvius erupted, which resulted in destroyed lives of citizens, it was estimated that there were 10 to 12 thousand people who occupied the city .The cities of Pompeii, Herculaneum and a few others were severely affected by the eruption. The cities are well known for its beautiful landscapes and its temperate climate.Pompeii is based in the south, close to Naples in the region of Campania in Italy.The eruption started a series of events such as pumice,rocks and ashes falling down and caused hot volcanic gases to rise high in the sky, people from around 100 miles away could see the event unfolding.The remains of Pompeii and other cities was frozen in time due to the pyroclastic surges
Mount Saint Helens and Mount Vesuvius are volcanoes that have erupted they are both different and also the same here are some facts, similarities and differences of both the volcanoes.

The ejecta from the eruption moved over land and through the air: the ash that fired out of the volcano was blown as far east as Nebraska in a huge, dark cloud of plinian ash. A nuee ardente billowed over the rim of the volcano and spread lava to the south, east and north, forming a volcanic outcrop now called the Bishop Tuff. Today, an expanding resurgent dome in the center of the depression indicates current magmatic activity beneath the caldera, and earthquake swarms in the last 25 years could also be linked to subsurface magma movement. Clearly, the Long Valley caldera is not dormant, so understanding the eruption that formed the caldera and surrounding features is essential to assessing the region's current and, more importantly, possible future activity.
Mount Vesuvius is one of history’s most recognizable Volcanoes, as each of its eruptions have gone down as a significant event in geologic history. The events that transpired during and after these eruptions have shaped the way scientists and people view the sheer power that these volcanoes possessed. This report will take a look at Vesuvius’ most prolific eruption in 79 AD. The geologic setting of the mountain, precursor activity, and the impact the eruption had on the surrounding populations and towns will all be detailed. Along with these details, this report will also look at the further history of Vesuvius’s explosive past by detailing its eruption cycle. Finally, the current state of Vesuvius and the possible danger the current population living near the mountain could face should it erupt explosively again.
Mount Vesuvius is located in the Bay of Naples in Southern Italy. Its Latitude and Longitude is 40.8224° N, 14.4289° E. It is a stratovolcano and has a height of 1277 meters (1490 feet) and base of 48 kilometers (30 miles). Mount Vesuvius has erupted over 30 times and has a repose time that can last for months or even years between eruptions. Its eruptions are explosive and is dominated by pyroclastic flows. The eruption materials are usually an ash cloud with lightening that spews out dense ash falls. The lava can shoot up to 4km into the air. The most famous eruptions of Mt. Vesuvius were in 79 A.D. which destroyed the cities of Herculaneum and Pompeii. The cities were covered in 20 feet of volcanic debris. The estimated death toll was over 1000 people. The
This eruptions cause a leatral blasts ,lava flows , hot ash flows and many other disaster .
These differences are in the makeup of the volcano, the impact on society, and the eruption itself. Mount Saint Helens, used to be a wonder of the world, but now a damage site of what happened on May 18, 1980. Mauna Loa is a tourist destination and one of the most active dispensers of lava and magma in the world. As shown, these volcanoes can’t be more different. Yet, each volcano has been a culprit to destruction, and have similarities within themselves. This report has expressed many similarities and differences and brought facts and knowledge to the historical eruptions by these impressive and ancient structures of
