Mount Fuji Research Paper

1714 Words7 Pages

Introduction
Mount Fuji is the tallest mountain in Japan standing at 12385 feet (3776 m) and is located on the main island Honshu 62 miles (100 km) southwest of Tokyo. It has a 78 miles circumference and a 25-30 miles in diameter around the base with a 1600 feet diameter crater. The mountain is surrounded by five lakes, Lake Kawaguchiko, Lake Yamanaka, Lake Saiko, Lake Motosuko, Lake Shojiko. The conic stratovolcano lies above a complex tectonic area known as the “Fossa Magna” which is the collision of the Philippine Sea plate with the Eurasian plate in the North and with the North American plate in the northeast. This junction is called the Fuji triple junction. There are different mythology related to Mount Fuji according to Buddhist and …show more content…

This particular earthquake was the largest recorded earthquake for Japan prior to 2011 earthquake. 49 days after the Hoei earthquake, on 16 December 1707, Mount Fuji erupted from three vents located on its southeast flank [Tsuya, 1955]. This particular eruption was a plinian eruption that produced 0.7 km^3 of tephra [Miyaji and Koyoma, 2007], and the emission was of mixed and mingled andesitic and dacitic tephras that was then followed by basaltic tephra [Tsuya, 1955]. According to Chesley (2012), the conduit was opened and the basaltic magma was pushed out of the chamber by unclamping of the deeper dike along with compression of the basaltic magma chamber. This basaltic magma then moved up the dike from the basaltic chamber 20 km deep into the andesitic and dacitic magma chambers creating magma mixing and rapid vesiculation. The magma then migrated from the 8 km deep chambers to the surface. The mixing can be found in the chemically zoned tephra deposits that include banded pumice of andesitic and dacitic composition [Yoshimoto, 2004]. Historical reports show that seismic activity started on the south flank of Fuji on 3 December 1707, 36 days after the Hoei earthquake, suggesting that magma migration started on or before 3 December 1707 and continued until the eruption on 16 December 1707 [Tsuya, 1955].

    (Harris, 2004) The downfaulting of Death Valley is correlated with the extension of the lithosphere in the Death Valley region, which plays a part to the uplifting associated with Sequoia – Kings Canyon National Park. The Batholiths of the Sierra Nevada mountain ranges are prominent in both parks, exposing “plumbing systems” in magma chambers that fed the volcanoes. “Magmatic differentiation” involves the crystallization of a magma with magma of a different chemical composition, creating more than one type of igneous rock, which can be seen in both Yosemite and Sequoia – Kings National Parks.

    This volcanism has included such notable eruptions as Mount Mazama (Crater Lake) about 7,500 years ago, Mount Meager about 2,350 years ago, and Mount St. Helens in 1980. Major cities affected by a disturbance in this subduction zone would include Vancouver and Victoria, British Columbia; Seattle, Washington; and Portland, Oregon. The two tectonic plates involved in the subduction process at the convergent fault line are the Juan de Fuca plate and the North American plate. The Juan De Fuca plate being the denser oceanic plate is being subducted under the continental North American plate. Although the fault line is on the coast of the Northern American plate tectonic activity is also heavily present inland, evidence of this is the cascade volcanic arc formed by the tectonic movements at the fault

Mauna Loa is the second tallest volcano in the world. The elevation is 13,679 feet high.

    Geology of the Hawaiian Island Chain The chain of Hawaiian Islands formed as the Pacific plate moved over a hot spot in the mantle of the Earth. The plate slowly moves northwestward at a rate of about 32 miles per million years. The northwestern islands are older and generally smaller due to prolonged exposure and erosion. Plate tectonics, types of volcanoes, hot spots, and sea mounts, are all an important part of the geology of the hawaiian island chain.

    Following up the information about the formation and deadliness of volcanoes is an example of a volcano, Mt.Tambora, one of the deadliest volcanoes ever. This volcano erupted over 200 years ago, but made a big impact all around the world. It erupted for three months in total. You could hear the explosions from over 1,000 miles away(Lassieur 4). This covered things in lava and was very hard to recover because the lava cools and hardens turning it into something as hard as bedrock(Lassieur 3).

    Many science organizations have agreed that the probability of another super eruption is a low probability chances are quite slim with estimates being a minimum of 1 in 730,000. Technology has gotten better and scientists are better able to detect a possible eruption before it happens due to the many warnings that would appear. There are some warnings before volcanic eruptions occur such as multiple minor earthquakes, land uplift, gas releases through the many small holes which help relieve pressure. In an article by the NSF which stands for National Science Foundation scientists believe that another eruption wouldn’t occur for another 1-2 million years because based on research of its caldera cluster the volcano is undergoing its dying cycle rather than its ramping up cycle. The foundation states that “by studying the pattern behavior of the cycles and its previous eruptions by examining the rock minerals in the vicinity they’re given better clues to suggest the volcano is on its calm stage”.

    There are many natural disasters that affect the world, for example, volcanoes. Mount St. Helens is known to be the most active volcano in the Cascade Range in Washington; effecting the people and the state. It was first recognized as a volcano in 1835! Before the eruption on May 18,1980, Mount St. Helens was a beautiful symmetrical cone, 3,000 meters above sea level. For most of the 20th century, many people viewed this mountain and recreation area as a beautiful and peaceful place, but after the volcano erupted in 1980 that view point was shattered.

    The poorly sorted nature of the conglomerates, considered with the inclusion of wood fragments in the older conglomerate members and the graded sandstones and mudstones throughout the formation suggest deposition occurred through successions of debris flows. Presence of volcanics in the lithic fragments further indicate volcanic activity in the process of sedimentation as well—as debris flows associated with lahars are the likely source of the slope failures. Deposition environment was moderate to deep marine, as mudstone deposits require low energy depositional environment, but the style of sedimentation indicate deposition was not on a continental shelf. This is further supported by inclusion of the large overturned clast from an older member within the formation. Cross-bedding, graded bedding, and scouring surfaces provide 3 lines of evidence establishing the northern contact of the formation as the original upward oriented surface.

    In theory, the Mauna Loa could have been erupting for 100,000 years. Mauna Loa is second youngest of the five of volcano on the Island of Hawaii. It began erupting about 700,000 to 1,000,000 year ago. It is one of the five volcanoes that was created as plates in the ocean moved over the Hawaii hotspot in the Earth’s underlying mantle. From the past, Mauna Loa had begun as a submarine volcano, growing underwater until it finally surfaced and created a great part of the land of Hawaii.

St. Helen was known as one of the most prestige volcanoes in the Cascade Range before its eruption on May 18, 1980. The eruption made a big blast that destroyed the northern part of the volcano, crushing millions of the trees below the mountain. The zone was further described as a big debris avalanche.
