Volcanoes and Volcanology - Volcanoes can be one of the most destructive forces on Earth. It is estimated that some 500 million people live near active volcanoes (Lutgens and Tarbuck, 2013). Of the Earth's known volcanoes, 70 can be expected to erupt each year with at least one large eruption each decade (Lutgens & Tarbuck, 2013). As populations continue to increase and more people are attracted to the beauty surrounding these areas, the immediate threat to humans from these sometimes sleeping giants grows. Due to this, the study of volcanoes and the service that volcanologists provide to the public by way of information and predictions on activity is immeasurable....   [tags: destructive force, volcanic eruption]

Understanding Volcanoes and their Types - ... An increase in silica concentration results in an increase in magma resistance to flow (viscosity). Andesite magma which have high content of silica compared to basalt magma make up most of the composite volcanoes fragmental materials. This silica-and volatile-rich magma is what separate composite volcanoes from shield volcanoes. Although, andesite magma dominate fragmental debris, some magma intrudes the cones such as sills or dikes. Due to this multiple intrusions, the strength of the structural framework is obtained and therefore composite volcanoes stand higher than those composed solely of the fragment materials....   [tags: vulcanology, earth sciences]

Lahars are hot flows of volcanic debris and water that are extremely destructive and travel very fast. Most of Mt Ruapehu's lahars have been caused by eruptions that have ejected water from the lakes in the craters. However, lahars can be formed by the collapse of a section of the rim around the crater lake. In 1953, a lahar from Mt Ruapehu was the cause of the Tangiwai Rail Disaster....   [tags: tectonic plates, erupt, ashfall] 1138 words

What Exactly Are Super Volcanoes? - Volcanoes have been around for many centuries and will continue to exist for many more to come. Many people have their ideas of what they believe volcanoes are. Most believe that it is basically a mountain that shoots out lava, destroying anything and everything nearby. This assumption is actually proven accurate. Volcanoes are considered one of the most dangerous natural disasters; they can erupt suddenly, destroying everything in its way. People tend to be so afraid of volcanoes that most of them don’t realize that there is one concept far more terrifying than just a volcano: a super volcano....   [tags: geological features]

Volcanoes and Earth - VOLCANOES AND THE EARTH SYSTEM EFFECTS OF VOLCANIC GASES Most of the gases in the atmosphere originally come from the Earth's interior. Gases within magma are dissolved because of high pressures beneath the earth's surface, but reduced pressure at the surface allows dissolved gases to expand and escape. When a volcano erupts, gases such as sulfur dioxide, carbon dioxide, chlorine, argon, sulfur, carbon monoxide, fluorine, and water vapor escape into the atmosphere. Although many of the gases emitted during a volcanic eruption can be helpful to the earth, a lot of the gases can be disruptive to the earth system....   [tags: Geology] 929 words

Kilauea and the Volcanism of the Hawaiian Islands - Kilauea is in the Hawaiian island chain, one of several dome volcanoes that form the big island of Hawaii. The unique feature of the islands stands in contrast to what we know about global plate tectonic theory and volcanoes that have formed around the ring of fire in the Pacific Ocean. Kilauea and the Hawaiian volcanic chain are driven by a geologic hot spot that is located in the middle of the Pacific Ocean. Thomas Jager was one of the pioneer researchers of Hawaiian volcanism and opened the way for the Hawaiian Volcano Observatory established in 1912....   [tags: Geology ]

The Effects and Causes of Volcanic Activity - Volcanoes are formed when magma is expelled from the Earth’s surface, resulting in volcanic eruptions consisting of ash and lava. Over time, the lava cools and forms into rock on the Earth’s surface. Whenever an eruption occurs, the newly-formed rock from the lava layers continuously until the volcano takes its shape. Volcanic eruptions have taken place for thousands of years, and even today, according to the U.S Geological Survey (2010), there are approximately 1500 active volcanoes located throughout the world....   [tags: lava, magma, volcanic eruptions, climate change]

Theories of Plate Tectonics - ... However, although there is significant evidence to suggest that volcanic and seismic events occur along plate boundaries, there are volcanic islands located away from plate boundaries. The theory of plate tectonics couldn’t provide an answer for the occurrence of intraplate volcanism. In 1963, J. Tuzo Wilson proposed the hot spot hypothesis. A hot spot is where a concentration of radioactive elements in the mantle causes a magma plume (streams of hot mantle rising from the Earth’s core-mantle boundary) to rise towards the surface, melting into the oceanic plate and eventually erupting lava through weaknesses and fissures....   [tags: hawaii, volcano, submarine] 1094 words

The quake was large and rocked the nearby towns of Pompeii and Herculaneum, doing extensive damage that would take years to repair. Due to the limited knowledge of geology at this time, Roman scholars were unable to make the connection between the earthquakes and the possible peril of a Mount Vesuvius eruption.(BBC) Some even argue that the people didn’t even know Vesuvius was a volcano....   [tags: eruptions, pompeii, herculeam] 1691 words
