  • Causes Of Mount Tambora

    Zachary Campanelli Gsci-131 Final Paper Mount Tambora is a volcano located on the northern coast of Sumbawa Island, Indonesia. The volcanic eruption in April 1815 is the largest recorded eruption in history. Mount Tambora forms the 60 kilometer long Sanggar Peninsula, previously standing at a height of approximately 5000 meters high. After the eruption, the volcano lost most of it’s top, now standing at 2,851 meters. Today the volcano still remains active. Smaller eruptions have taken place in 1880 and 1927. There have also been periods of increased seismic activity in 2011-2013. Tambora is the largest recorded eruption in all of history. On April 5, 1815, a modest eruption had occurred, followed by rumbling noises. By April 10, Ash had begun to fall as well as the continued noises. Later that night a full force explosion occurred which could be heard over 1,200 miles away. The top of the volcano actually blew off during this explosion. The ground shook, massive boulders flew from the volcano, and large pillars of flame shot upward carrying gas, dust, and smoke into the sky. Rivers of burning ash raced down the slopes of the mountain, destroying everything they crossed, before pouring into the sea. The results of this eruption could be seen by people living hundreds of kilometers away. Tsunamis resulting from the pyroclastic flows pouring into the sea went as far as the island of Java located approximately 500 kilometers away, two hours after the eruption and two meters…

  • Sacrifice In Northern Minnesota

    The basalt along the North Shore came from the Mid-Continent Rift. There has been many different basalt lava flows in the North Shore. In Two Harbors, the basalt that would have been on the top of the lava flow is littered with amygdules. An amygdule is just a gas bubble or vesicle that has been filled with minerals. The basalt under the amygdaloidal basalt formed at the bottom of the lava flow because it doesn’t have any amygdules. In Gooseberry Falls, the amygdaloidal basalt is at the…

  • Adakite Research Paper

    Introduction Adakites are volcanic rocks that are diagnostic of high temperature, high pressure conditions, (Stevenson, 2005). Their composition ranges from felsic to intermediate, and are characterized by assemblages of plagioclase, and often amphibole, and are identified by their unique geochemical signatures. Adakite is named Adak Island, Alaska, where it was first documented,(Defant and Drummond, 1990). They are often formed through the partial melting of a young subducting slab of…

  • Fantale Geothermal Energy Case Study

    4.2.5. The Fantale geothermal prospect area The Fantale geothermal prospect is characterized by recent summit felsic lava, caldera collapse, extrusions in the caldera bottom and widespread fumarolic activity, signifying thereby the existence of a shallow magma chamber (Tekelemariam and Beyene, 2005). Active tensional tectonics form fissures up to 2m near the volcanic complex. From the area ground water discharge to the system is guaranteed by the proximity of the area to the western escarpment.…

  • A Short Summary On Onyx

    Onyx: The Practical and Metaphysical Story Onyx is a specific variety of the mineral known as chalcedony. It is a banded mineral, which means that the layering of the rock that formed it has caused “bands” of different colors to appear. Many people mistake onyx for a type of agate, which is another type of chalcedony, but where agate has curved bands onyx has parallel bands instead. Onyx is found in nearly every color, though bands of black and white are the most common. When onyx is banded…

  • Earthquakes And Volcanoes Research Paper

    Lesson 1: Earthquakes and Volcanoes Layers of the Earth Earth is made up of three layers: crust, mantle and core. The outer layer is the crust, the middle layer is the mantle and the inner layer is the core. Earth's crust and upper mantle are broken into large plates that move slowly. Figure 1 shows the layers of the Earth. Figure 1: Layers of the Earth Plate tectonics The Earth's surface is formed of large pieces of rock called plates that are also called tectonic plates. These plates…

  • A Poem In Relation To Natural Selection

    A Poem in relation to Natural Selection When one thinks of a giant crack of lighting whitening the sky or the massive roaring of an erupting volcano, the first thing that might befall their mind is violence and destruction.
