Fuji is also known as one of the three ‘holy’ mountains along with Mount Tate and Mount Haku Fuji stands 3776 meters (12380 feet). It’s still an active stratovolcano and sits on a triple junction of tectonic movement. Fuji is approximately 100km (62 miles) from the largest city and the capital of Japan, which is Tokyo. The last time Fuji erupted which was between 1707 and 1708, volcanic ash fell

    Krakatau, West of Java I. Introduction Krakatau is a former stratovolcano that is located within the Sunda Strait between Java and Sumatra. The most popular and logical theory for the origin of its name is that it was adapted from the sanskrit word “Karkata”, justification being that Rakata is cited as meaning crab in the older Javanese language (Wilson, 1999). The origin of this volcano is perhaps first noted in the Javanese Book of Kings in 416 A.D. as a “thundering sound” in Kapi, a westward

    Mount Mazama Essay

    • 3 Pages

    For more than 100 years, scientists have sought to unravel the remarkable story of Crater Lake’s formation. Before Crater Lake came into existence, a cluster of volcanoes dominated the landscape. This cluster, called Mount Mazama (for the Portland, Oregon, climbing club the Mazamas), was destroyed during an enormous explosive eruption 7,700 years ago. So much molten rock was expelled that the summit area collapsed during the eruption to form a large volcanic depression, or caldera. Subsequent smaller

    Volcanoes are magnificent and powerful land features. The magma erupts from the Earth forming islands, cooling to form rocks, and changing the landscape on eruption at a time. They can erupt at any time! Since volcanoes are dangerous we have developed technology to detect these impressive explosions. Since Hawaii was formed by a volcano when you visit Hawaii you are standing on cooled lava! There are 3 different stages a volcano can be in and 2 very different types of explosions that can happen.

    In this essay, I will analyse the different types, geochemistry, constitution, identifying characteristics and consequential activity levels of volcanoes, with a particular focus on Stratovolcanoes and how they compare to the other known types and specifically the magma constituency, viscosity levels and mineral content when compared to that of other types of volcano. Stratovolcanoes which are also commonly known as composite volcanoes are composed of many different strata or layers of pyroclastic

    Volcanoes are mountains with a large pool of magma. When pressure builds up the magma and lava spews out, this is called a volcanic eruption. So, how are volcanoes formed? Volcanoes form in destructive and constructive areas on Earth. They form when plates in Earth’s core (tectonic plates) force molten rock, gases and ash to Earth’s upper mantle. The magma lives in the Earth’s crust. Magma is made from rock and gases. When two tectonic plates collide they push magma to the Earth’s surface and as

    Introduction A natural disaster is an extreme event; caused by a natural phenomenon that has severe, adverse affects on human lives and livelihoods (Encyclopedia of Natural Hazards, 2013). This was certainly the case during the geophysical event that occurred in 1902 on the island of Martinique. The volcanic eruption of Mt. Pelee devastated the city of St. Pierre, destroying the city and killing much of the population in a matter of only a few minutes. Disaster Location Mount Pelee is located on
