A volcano is a weak spot in the crust where molten material, or magma, comes to the surface. In a volcano there is a magma chamber, pipe, vent, lava flow, and craters. A magma chamber is the pocket where magma collects under or below a volcano. The pipe of a volcano is the long tube in the ground that connects the Earth's surface to the magma chamber. A vent in a volcano is where the molten rock and gas from the volcano leave through an opening. The lava flow is a certain area that is covered by lava that is coming out of the vent. Lastly, a crater is a bowl shaped area that is formed at the top of the volcano. The eruption of 1912 or Mount Katmai was the biggest eruption of the 20th century. Located along the Alaskan Peninsula …show more content…
An active volcano is a volcano that's erupting, supposed to erupt in the near future, and has had an eruption in the last 10,000 years.An active volcano can be erupting or dormant. Dormant volcanoes are active volcanoes that are supposed to awaken in the near future and become active. A extinct volcano is a volcano that is “dead” and unlikely to erupt again. The Katmai volcano is active-dormant. This is because it has erupted in the last 10,000 years and will most likely erupt again. The activity of the Katmai volcano has not changed over time. There has only been one eruption that has been officially recorded with evidence, which was the eruption of 1912. The eruption of 1912 was the biggest eruption of the 20th century. There were aftermath disasters. There was noise pollution, the sound of the blast was heard in Juneau, Alaska 750 miles away from the volcano. The volcano continued to erupt gas and tephra for 60 straight hours. The eruption caused people and animals on Kodiak Island to evacuate. Anyone who didn't evacuate quick enough died from suffocation, blindness, or inability to find food or water. The ash built up to 1 foot on the ground. Also ash built up on roofs causing buildings to collapse on

On May 18th, 1980 one of the worst volcanic eruptions occurred in the United States. Triggered by an earthquake, Mount St. Helens erupted in Washington State at 8:39am. According to the National Oceanic and Atmospheric Administration, it was "the deadliest and most economically destructive event in the history of the United States." There were many effects from this terrible, natural event. People, animals, and the environment were all effected.
Mount Redoubt is an active volcano. A volcano is an opening on the surface of the Earth letting the hotter material inside escape the mountain or hill. (Magma or Lava) When that magma escapes, the mountain creates an explosion. If a volcano has erupted in the last 10,000 years then it is still considered an active volcano.
With no prolonged periods of inactivity the volcano has continuously built up on itself. The last major eruption took place in 1790 and killed many people and animals, but numbers are unknown4. Starting in 1983 there was a chain of several eruptions that started and have yet to stop pushing lava through a lava tube till it reaches the Pacific Ocean. Over a span of twenty year the flow has
11. The Kilauea Volcano eruption was one of the largest and the most destructive for its time, “As the lava field spread, cooled and spread again over the next three years it destroyed many homes and the Visitor Center…” (http://www.livescience.com/27622-kilauea.html) Familys and companys had no were to go, jusst like the the people in the Dust Bowl at the
Imagine a single event that can kill 57 people and 7000 deer and elk. Snap trees like a toothpick, and turn the sky grey for 15 days. Now, stop imagining, Mount St. Helens, in the Cascade Range of southwestern Washington State, erupted. On May 18th,1980. According to (Campbell 371), “At least $1 billion in economic damage was reported”. The eruption of Mount St. Helens took many lives, and devastated America. Mount St. Helens destroyed more than 230 square miles of ancient forest.
After more then 40,000 years of activity, one would expect that people would no longer live in the surrounding shadow of Mt. St. Helens. But regardless, many towns and cities sit inside of a zone that would face destruction if a large eruption took place. In 1980 Mt. St. Helens erupted and caused the loss of many lives and the destruction of thousands of miles of land and property. Following the eruption, the volcano has stayed extremely active. In 2004 it erupted again, building a new lava dome and sending ash and steam into the atmosphere. Since then, seismologists and volcanologists have recently discovered pockets of magma rising and that another eruption may occur soon. Even though the people of Washington know that an eruption could cause widespread devastation they continue with their lives, doing little to prepare for the potential disaster.
A volcano is an earth hazard that occurs on faults between tectonic plates on a destructive boundary and an eruption is a natural disaster. A primary impact happens immediately after the disaster and before any response like death or collapsing or destruction of buildings. A secondary impact occurs later after the disaster, such less farm produce or a reduction in tourism. The severity of these impacts will differ considerably in a MEDC and LEDC where volcanic eruptions have taken place. These may be seen in the Mount St. Helen volcano eruption as well as in the Iceland volcanic eruption. They may also
It was May 18th, 1980. The eruption of Mount St. Helens occurred in Washington,United States. The exact time it had happened is at 8:32:17. The eruption happened 96 miles out South of Seattle, Washington and 50 miles northeast of Portland,Oregon. Many people died during this time. About 50 people had died. 250 homes were destroyed. Along with 47 bridges, 15 miles of railways, 185 miles of highway was also destroyed. Many tiny earthquakes had happened a couple days before the eruption had happened.
On the 12th of June (Philippine Independence Day), millions of cubic yards of gas-charged magma reached the surface and resulted in the first major eruption which was then followed by a series of eruptions. It produced a 19 km long ash column and pyroclastic flows that extended up to four km from the summit to the river valleys. Later, a 15 minute eruption hurled ash straight up to the sky, reaching the heights of 24 km. The super heated air and the friction between
The Mexican volcano experienced its largest eruption in 1913, which lasted for 4 days, and formed a crater 300 meters in depth (http://volcano.oregonstate.edu/colima). Experts show concern that the volcano is exhibiting many of the
All human expression can be broken down into four basic emotions- happiness, sadness, anger, and fear. Of these emotions, none can contest with the influential effects of fear. Throughout history, we have seen the devastating impacts of fear in slavery, Stalin’s brutal reign over Russia, and most significantly, the Nazi party. Fear has constantly been shown to possess and control people to engender dire consequences, much like it does in Alan Paton’s novel Cry, the Beloved Country. In his novel, Paton examines the negative impacts of fear, namely prejudice and corruption. Set in South Africa, the main character, reverend Stephen Kumalo, observes the stark contrast between his poor village and the cosmopolitan city of Johannesburg. Throughout the story, he unearths the changes occurring in South Africa as a result of escalating racial tensions. His journey brings him to an understanding of the harsh struggle of his fellow Africans, and he too begins to experience the growing fear. Paton explicates that eradication of fear is of utmost importance in fashioning a unified country, and if we fail to set aside our fears, we must forever bear the scars of prejudice and corruption.
The volcanoes are located where there is a divergence or convergence in the tectonic plates and bring their lava from the deepest of the terrestrial mantle. The materials and explosions of these ginates represent a constant risk in the places inhabited by the human being, nevertheless the people ususually live in these areas no matter the risk. On the other hand the volcanos can change the geology of an impressive form, or to cool the temperature of the earth, or to darken the sky. The scientific community increases its efforts to try to understand better what happens in volcanoes, however it is impossible to predict these conditions.
The estimated age of the earliest above ground (subaerial) eruptions of Kilauea is between 50,000-100,000 years.
American literature is filled with classic stories that give the public not only a form of art but also ways to dissect the story and gain a better understanding of the author 's intent. Literary themes allow us to explore meanings deeper than the surface level. Imagery is the author 's use of wording that allows the reader to experience everything mentally as they read. This is not limited to sight, but all five of the senses.
