Volcanology

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. Pg13 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) 2.3 Volcanic Ash Volcanic ash or sand is volcanic material debris…

In 79 CE, August, Mount Vesuvius had a significant eruption, that went on for nineteen hours, burying an ancient Roman city for seventeen centuries. This city was near the modern Naples within the Italian Region of Campania. The buildings and many of the people were buried and lost until the discovery made in 1738. This city is known as the lost city of Pompeii. Mount Vesuvius is a stratovolcano that consists alternate layers of ash and lava. Stratovolcanos have two types of eruption, one…

Sharpe 1 Grace Sharpe Professor Fara Lindsay Earthquakes and Volcanoes Homework 1 June 15th, 2016 Sabancaya The volcano I choose to write about is none other than the Sabancaya volcano. It is located in the Andes mountains in Peru. This particular volcano is a stratovolcano part of a collection of three glacially covered volcanoes. The elevation of the Sabancaya volcano is 5967 meters high and it is the smallest of the three, however, it happens to be the most active. Volcanic ash and…

Hanauma Bay in Hawaii Island The Hawaii Island in one of the worlds beautiful Biosphere reserves. It is an international destination too for its unique bio diversity. No such island is there in the planet Earth. This is also one of the remote Islands in the Pacific Ocean on the northern Hemisphere. The Hanauma bay is also one of such important tourist attraction in the Hawaiian Island. There are many number of tourist packages available in the web. It is advisable to buy through online for…

Vesuvius erupted in 79 AD and covered herclum in mud and ash, this paper will talk about the causes of volcanic eruptions, what happened In pompeii and herculaneum, and what was my personal reaction What Causes a Volcano to Erupt A buildup of pressure and less dense magma on the bottom can cause an explosive eruption. An eruption from a volcano can also be because of an earthquake that shakes the volcano and makes it unstable. An explosive eruption will cause rocks and ash to fall from the…

The Galapagos Island is apart of Ecuador that caused by the volcanic eruption and lava accumulation of many years ago, It’s a paradise for most adventurer. On the Galapagos have a many creatures and species even though plants and animals. So they are not in another islands and we have an example to show you all. “Galapagos tortoises” are known to be the biggest and oldest tortoises in the world. The average life span of these tortoises are 170 years or more because they are listed as endangered…

Mount Cleveland is one of Alaska’s most active volcanoes. It has erupted more than 20 times in 230 years. Mount Cleveland is a nearly symmetrical, stratovolcano on the western end of Chuginadak Island, which is part of the Islands of Four Mountains. The Islands of Four Mountains are just west of Umnak Island in the Fox Islands located in the Aleutian Islands of Alaska. In 1894 a team from the U.S. Coast and Geodetic Survey (formerly the United States Survey of the Coast) visited the island and…

Explosive volcanoes are one of the most dangerous natural occurrences on the planet, but the types of volcanoes that can destroy the world are know as super volcanoes. Super volcanoes are determined by past explosion and this volcano can be located in the United States called Yellow Stone. Their criteria also depend on the volume of an eruption, for a super volcano the eruption must be more than 240 cubic miles of pumas and ash. There had been three super explosions that fit the criteria at…
