Volcano Facts Fun Volcano Facts: • a Volcano Is an Opening (Usually in A

Fun Volcano Facts: • A volcano is an opening (usually in a mountain) in the Earth’s surface from which gas, hot magma and ash can escape. • The word volcano comes from the Roman name “Vulcan” – the Roman god of fire. • The hot liquid rock inside a volcano is called magma, but once it leaves the volcano, it’s called lava. • Volcanic eruptions can send ash over 17 miles into the air above the Earth’s surface. • Most volcanoes are located above where tectonic plates meet. This is especially true for the Pacific Ring of Fire, located in the basin of the Pacific Ocean. There you can find 452 volcanoes, over 75% the world’s active and dormant volcanoes. • Most volcanoes form near tectonic boundaries, but they can also form in areas that contain abnormally hot rock inside the Earth. Known as mantle plumes, these hotspots are found at a number of locations around the globe. Facts about the eruption of Mount Vesuvius and the preservation of Pompeii: • One of the most noted natural disasters in the world was the eruption of Mount Vesuvius on August 24, 79 A.D. It sent a cloud of ashes, pumice, rocks and hot volcanic gases into the sky that people could see for hundreds of miles. • The large amount of ash (known as a pyroclastic flow) that covered the city acted as a preservative. During a pyroclastic flow, enormous volumes of extremely hot gases, ash, and rocks rush down the side of a volcano, like an avalanche; there are also big explosions and large, billowing clouds. This mixture of ash, rock and gas, covered the city and froze it in time. • Ironically, the eruption of Mount Vesuvius in 79 A.D., happened just one day after VULCANALIA, the festival of Vulcan, the Roman god of fire, for whom volcanoes are named. • Archeologists set out to excavate the city from the ashes that surrounded it in 1748. • Mount Vesuvius is still active today. It has produced some of the continent’s largest volcanic eruptions. Located on Italy’s west coast, it overlooks the Bay and City of Naples. Volcano Facts .

Mount Vesuvius Is Located on the Gulf of Naples, in Italy
Mount Vesuvius is located on the Gulf of Naples, in Italy. It is close to the coast and lies around 9km from the city of Naples. Despite being the only active volcano on mainland Europe, and one of the most dangerous volcanoes, almost 3 million people live in the immediate area. Did you know..? Mount Vesuvius last erupted in 1944.

This is a series of volcanoes that are active, dormant or extinct. Vesuvius Campi Flegrei Stromboli Mount Vesuvius is actually a Vulcano Panarea volcano within a volcano. Mount Etna Somma is the remain of a large Campi Flegrei del volcano, out of which Mount Mar di Sicilia Vesuvius has grown. Did you know..? Mount Vesuvius is 1,281m high. Mount Etna is another volcano in the Campanian arc. It is Europe’s most active volcano. Mount Vesuvius last erupted in 1944. This was during the Second World War and the eruption caused great problems for the newly arrived Allied forces. Aircraft were destroyed, an airbase was evacuated and 26 people died. Three villages were also destroyed. 1944 was the last recorded eruption but scientists continue to monitor activity as Mount Vesuvius is especially dangerous. Did you know..? During the 1944 eruption, the lava flow stopped at the steps of the local church in the village of San Giorgio a Cremano. The villagers call this a miracle!

This colonnade forms part of the forum. The forum was a public square which would have been used for meetings, criminal trials, public speeches, and markets. Colonnade Many streets remain in Pompeii. Here you can see cobbled streets with pavements on each side. In the distance is Mount Vesuvius – the volcano that destroyed Pompeii. Street In ancient Pompeii, there were many types of entertainment. One popular pastime was the theatre where people went to watch plays. This theatre had space for 1,000 spectators. Odeon – small theatre The Romans worshipped many gods. This temple is dedicated to Apollo, the god of music, and was built on a high platform to make it look more impressive. Temple of Apollo The House of the Vettii was one of the most impressive and richly decorated houses in Pompeii. It was named after the owners, Aulus Vettius Conviva and Aulus Vettius Restitutus. House of the Vettii The Romans use mosaics to decorate wealthy houses and public buildings. Each mosaic used thousands of tesserae (small pieces of tile or stone) to create a picture or pattern. Mosaic Another popular way of decorating rooms was with wall paintings (frescoes). This one, in the Casa del Menandro (House of Menander) shows a hunting party. Can you see the dogs and the man with a bow and arrow? Paintings in Casa del Menandro Myths and legends were a common source of inspiration for Roman artists. This painting depicts Narcissus who was so beautiful that he fell in love with his own reflection. Painting of Narcissus Archaeologists at Pompeii have found so many artefacts, it is not possible to have them all on display at once.

Educators Guide
EDUCATORS GUIDE 02 | Supervolcanoes Volcanism is one of the most creative and destructive processes on our planet. It can build huge mountain ranges, create islands rising from the ocean, and produce some of the most fertile soil on the planet. It can also destroy forests, obliterate buildings, and cause mass extinctions on a global scale. To understand volcanoes one must first understand the theory of plate tectonics. Plate tectonics, while generally accepted by the geologic community, is a relatively new theory devised in the late 1960’s. Plate tectonics and seafloor spreading are what geologists use to interpret the features and movements of Earth’s surface. According to plate tectonics, Earth’s surface, or crust, is made up of a patchwork of about a dozen large plates and many smaller plates that move relative to one another at speeds ranging from less than one to ten centimeters per year. These plates can move away from each other, collide into each other, slide past each other, or even be forced beneath each other. These “subduction zones” are generally where the most earthquakes and volcanoes occur.

Travel Through the History of Mount Vesuvius
Travel Through the History of Mount Vesuvius Mount Vesuvius is one of the most well-known active volcanoes on the planet, and by far the most famous in Europe. It is about 30 thousand years old, but its most famous eruption impacted human history forever at Pompeii. Since then, it has been grumbling in Italy near Naples for about two thousand years. The results of the famous eruption froze an entire city, a beautiful time-capsule of an early Roman society, has encouraged travel to tourists and historians from all over the globe. Mount Vesuvius Despite its age, Vesuvius is still regarded as an active volcano. It is intensely monitored for activity, as about 3 million people live within range of its eruptions. Volcanoes are created due to irregularities in heat from the earth's mantle. Melting and cracking ensues and bubbles up from the surface. Vesuvius is classified as a stratovolcano, also known as a composite cone, similar to other famous volcanoes such as Mount Fuji in Japan and Mount Saint Helens in the United States. Statovolcanoes are dangerous due to their highly variable content, and eruptive style. Plinian eruptions, which Mount Vesuvius has produced, result in plumes of ash ascending up into the stratosphere, high above the earth's surface. Mount Vesuvius can produce both eruptions of ash and pyroclastic flows, making it unique. Even though all of this can be dangerous to humans, volcanoes like Vesuvius are important in the lifecycles of rocks on Earth. • Mount Vesuvius Image from Space • How Volcanoes Work ï¿½ Stratovolcanoes • Volcanic Landforms and Plate Tectonics • Teacher and Lesson Resources for Vesuvius Pompeii On August 24, 79 CE., an individual nicknamed Pliny the Younger, or Caius Plinius, witnessed the horrible eruption that swept through Pompeii and Herculaneum in a letter to Cornelius Tacitus.

Structure of the Mount Vesuvius Volcano from Geophysical Exploration

Vassallo1,2; A. Zollo1; G. Festa1; C. Satriano2; L. D’Auria3; P. Gasparini1,2 and P. Strolin1 1 Dip. Scienze Fisiche, Università di Napoli Federico II, Italy 2 AMRA S.c.a.r.l., Napoli, Italy 3 Istituto Nazionale di Geofisica e Vulcanologia, Osservatorio Vesuviano, Napoli, Italy Mt. Vesuvius is a strato volcano near a densely populated area and only a few km southeast of Campi Flegrei, the active calderas on which the city of Napoli has been built. It is composed 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. It experienced at least three violent explosive eruptions in historical times (79, 472, and 1631 A.D.). More frequent, less explosive eruptions have occurred from 1631 to 1944. Mt. Vesuvius is presently in a quiescent state, characterized by low-temperature fumaroles (less than 100°C) and moderate seismic activity (about 100 earthquakes per year with magnitudes between 0.5 and 3.6), and it is difficult to predict when it may erupt explosively again.

Mount Etna Kilauea
Mount Etna Location: Sicily, Italy Height: 3,329 m (10,922 ft) Formed: 500,000 years ago Status: Active Mount Etna is the tallest active volcano in Europe, and the 59th tallest volcano in the world. It is also one of the most active volcanoes in the world, in an almost constant state of volcanic activity. This is due to the fact that it sits on top of the convergent boundary between the Eurasian and African tectonic plates. Throughout its history the eruptions of Mt. Etna have alternated between explosive, violent eruptions and flowing, gentle eruptions. There have been several major eruptions of Mt. Etna, leading to the formation of calderas on the summit of the mountain. Between 35,000 and 15,000 years ago, Mt. Etna released large pyroclastic flows, some of which traveled as far as 800 km from the volcano. In the last 100 years, there have been several major eruptions. These occurred in 1928, 1949, 1971, 1981, 1983, 1991, 1993, every year from 2001-2005, every year from 2007-2009, 2011, 2012, 2014, and most recently on December 3, 2015. Although Etna’s eruptions have been known to be violent and destructive, it has only claimed 77 lives in recorded history, and most of the damage it causes is to property and structures. In fact, most citizens that live near Mt. Etna consider it be a blessing, as its volcanic soils are rich and good for farming. Mt. Etna is closely monitored and is one of the most popular tourist destinations in Italy. Kilauea Location: Hawaii, U.S.

Pliny the Elder once called the area one of the loveliest places on earth. Vesuvius had not erupted since the Bronze Age, and the Romans believed that the volcano was dead. Although occasional earthquakes rocked the area, the most violent being in 62 or 63 A.D., the inhabitants did not connect the vibrations to the long silent mountain. On October 24th, 79 A.D.,* catastrophe struck, and Pompeii was lost to the fury of Vesuvius. The poignant stories of the people of Pompeii are heartbreaking, and sometimes difficult to read, but must be told. Eruption During the summer of 79 A.D., the fires built beneath the mountain. Small tremors increased to the point of becoming a normal part of life. The shifting of the earth cut off Pompeii’s water supply, and the volcano rumbled and growled. The citizens of Pompeii spent a sleepless night on the 23rd of October, as the shocks grew frequent and violent. When morning dawned, they rose to begin their day as usual.
