1111254292600Earth and tectonic plates
The earth is made up of 4 different layers. As shown in Appendix A, the earth’s made up of the inner core, outer core, mantle and crust (or lithosphere). The earth’s tectonic plates make up the crust. So, when they collide, they move continuously above the mantle which causes Earthquakes and, in this case, Volcanoes to erupt (Cain, 2018).

There are two crusts. The continental crust, which carries the land and the Oceanic crust, which carries water. These two crusts move across the surface of earth and meet at plate boundaries (“Volcano – Volcanoes related to plate boundaries”, 2018).

A volcano is a vent in the earth’s crust where molten rock, gas and steam are wrapped onto the planet’s surface (Cain, 2018). They are most common in areas of seismic activity such as where the earth’s continental plates (Appendix B) pull apart or collide. They also occur far from plate lines in hot spots where the earth’s crusts melts. An example of such a hot spot is Hawaii’s volcanoes. Volcanoes exist on all continents except Australia and form in ocean trenches. The molten rock beneath the earth’s surface is called magma. Lava refers to the magma ejected from a volcano. Magma’s mineral composition determines how its lava behaves.

Seismologists classify volcanoes as active, dormant and/or extinct.
Active volcanoes are either erupting or likely to erupt in the future (Appendix C. i).

Dormant volcanoes have not erupted in recent history (Appendix C. ii)
Extinct volcanoes have exhibited no activity for long periods and are unlikely to erupt in the future. (Appendix C. iii)

47434500Composite Volcanoes
Composite is defined as something being made up of several parts or elements. So, composite volcanoes are made up of multiple eruptions. So, overtime the lava cools down and forms a thick layer of crust near the vent opening giving it a conical shape (Cain, 2018). The lava that comes out of these types of volcanoes is thick (high viscosity lava). An example of a composite volcano is Mt. Fuji in Japan. This is Japan’s highest mountain and most recognized feature. This mountain was created by a series of eruptions through many years. Below is an image of Mt. Fuji.

Shield volcanoes are the largest of all volcanoes on the earth. The Hawaiian volcanos are a perfect example of shield volcanoes in the earth (Geographic, 2018). The unique thing about these volcanoes is that if you look at the picture they resemble the shape of a warrior’s shield. Many of the volcanoes on the Hawaiian Islands are shield volcanoes (Geographic, 2018). They are usually low with gentle sloping sides, formed by eruptions of thin runny lava and they erupt often but not very violent. Below is an image of what a shield volcano looks like.

Volcanoes are classified based on their nature of eruption, that is how they erupt and based on the formation that is the physical structure. There are 4 main types of volcanoes the shield volcanoes, Composite volcanoes, Caldera volcanoes and Lava domes

Mt Vesuvius is in the European continent and is famous for its unpredictability of eruptions. It is said that Vesuvius erupted eight times, 17,000 years ago (Harriet, 2018). Vesuvius last erupted in 1944. This volcano is well known for its violent past. Mt. Vesuvius is still very much alive and only now are its mysteries being revealed. A new discovery of a vast magma chamber of boiling hot rock beneath Vesuvius. Just one of many startling new clues to how the volcano could threaten one of
Europe’s most crowded cities with a fiery rain of death and destruction. The next eruption at Vesuvius could kill more people than any other volcano in history. 3 million lives are at risk.

51621072121195On the West coast of Italy (Appendix D for location), towering 4,000 feet over the city of Naples, stands Mount Vesuvius.

It’s the nightmare scenario that everyone fears, a cloud, a fiery debris would blast down the steep sides of the volcano at 450 miles per hour. Which is TWICE as fast as a formula one racing car (Harriet, 2018). Anyone within 10 miles of the crater would be caught in the eruption’s death zone. Nothing can stop this boiling cloud of ash and rock. There’s nowhere to hide. Men, Women and children are incinerated. Below is a quote written by the only eyewitness, Pliny the younger to historian Tacitus Anyone, during the eruption of Vesuvius, between downtown Naples and the volcano is dead.
If Vesuvius has produced such a massive eruption once, it can again.

5243460357299005080260350Caldera Volcanoes
These are the most explosive volcanoes (Ball, 2018). They’re usually so explosive that when they erupt they tend to collapse on themselves instead building a tall structure. When I say explosive, I mean how hard it shoots upward because if the eruption is not explosive then the lava would flow in a nice river format. Explosive eruption means shooting harder upwards. So, Caldera volcanoes are explosive because the vent opening collapses on itself (Ball, 2018). An example of a Caldera volcano is Mount Okmok in Alaska. Below is an image.

A lava dome or volcanic dome is a rough, circular, mound shaped protrusion resulting from the slow extrusion of vicious lava from a volcano (Harriet, 2018). Since the lava is too vicious (or thick) it doesn’t flow too far. Unlike the Shield volcanoes the magma from lava domes just pile up over and around the vent. The dome expands because of the lava that is inside.
