dangerous part of the world’s landscape. But then people began to study volcanoes, trying to figure out what makes them tick. They wanted to discover how volcanoes formed and especially, what causes them to erupt.
The study of volcanoes became a special interest for many geologists. They were called volcanologists. Volcanology specifically studies the processes that affect magma flow and eruption through vents in the surface of the earth.
Volcanologists usually get their college degree in geology, geochemistry, or geophysics. Then they specialize in volcanoes. In general, geology deals with the earth’s physical structure. Geochemistry focuses on the chemical composition of the earth. Geophysics deals with understanding the earth’s geology by using physics and mathematics.
Volcanologists specialize in different areas that are related to volcanoes. Physical volcanologists gather data and study actual volcanic eruptions and their deposits. They map the deposits that make up the volcano and collect samples to analyze. By dating and identifying the volcanic samples, they learn about the volcano 's history.
Geophysics is another branch of volcanology. These scientists study the frequency of earthquakes close to a volcano. They also study and analyze a volcano 's gravity and magnetics.
Geodesic volcanologists study how the shape of the earth changes from volcanic eruptions. Geochemists are also volcanologists. They study what volcano produces, including magma and…
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.…
2.2.3 Definition of Chelating Ligand EDTA
From the above discussion, it can be concluded that chelating ligand EDTA is a process of reversible bond formation of a ligand that serves as chelating ( chelting agent or Chelator) that exist within the compound of EDTA. Basically, EDTA combines with some specific ion, so it causes the functions of EDTA as chelator. When the functions of EDTA as chelator, EDTA is a liquid ( solution)

Prose Comparison - European Baccalaureate 2016
Both prose pieces revolve around a common event: the eruption of the volcano Vesuvius in Pompeii. On the one hand, Passage b) recalls the eruption from the present time - an article published in The Guardian - whereas Passage a) narrates the incident in real time - an extract from the novel Naples ‘44. However, these two pieces of prose do not appear to concern themselves with the same eruption. Passage a) relates to the eruption during the Roman…
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. Watching the wrath of mother nature before your eyes can be disheartening. Several movies have depicted her power such as San Andreas (2015), and Geostorm (2017). While these movies are fictional they do display how terrifying nature can be to the frailty of life.…
Mount St. Helens is an 8,363-ft. tall volcanic landmark of the state of Washington. It was a popular tourist attraction and recreation area for most of the 20th century. It was also The U.S.’s 8th tallest mountain, towering at 9,977 ft. It is now the 14th tallest at 8,363 ft. tall, due to a major eruption in May of 1980. On May 18, 1980, the beautiful, peaceful well-known mountain Mount St. Helens became the most dangerous mountain in U.S. history in a matter of minutes. There are records of…
Kyushu Figure 1.1: Map Japan
Kyushu is the third biggest island located in the south of Japan. Kyushu has a subtropical climate and offers active volcano peaks, natural beauty and near-tropical coastlines (Lonely Planet, 2015).
Mount Aso is the largest active volcano, which is situated in the Aso region in Kumamoto Prefecture (Organization, 2015). This is an opportunity to attract tourism to Kyushu.
Fukuoka is the…

Toba, the Deadliest Volcano Eruption
Around 74,000 years ago during the Quaternary period, the supervolcano known as, Toba, erupted in Northern Sumatra, Indonesia. Toba is thought to be one of the largest known eruptions the Earth has ever seen. And certainly the largest to erupt during the Quaternary period. Out of the three periods that make up the Cenozoic Era, the Quaternary period is the current and most recent of the three. The eruption of the Toba volcano did not…
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…
