Yellowstone National Park was named after the Yellowstone River. Native Americans called the river “Mi tsi a da zi,” which meant “Rock Yellow River,” and was translated by French fur trappers to “Yellow Rock” or “Yellow Stone,” hence the name Yellowstone. John Coltzer was one of the first people to have explored the Yellowstone area. Coltzer was from the Lewis and Clark expedition and he walked alone through this area in 1807 while in search of furs. Since 1827, though, Yellowstone has been a

either case, this activity (vulcanicity) may have a profound effect on surface features. It may be pointed out that there are two forms of vulcanicity: intrusive and extrusive. A volcano, on the other hand, is the resultant effect of the process of vulcanicity. A. Holmes has defined a volcano as under: "A volcano is essentially a fissure or vent, communicating with the interior, from which flows of lava, fountains of incandescent (red-hot) spray, or explosive bursts of gases and volcanic ashes

It has nearly been 5000 years since the discovery of a volcano located under House Mountain State Park in Tennessee occurred. The volcanic ash covered the 500 acres of the state park, as well as some of the neighborhoods of Corryton and Mascot. The year is 7016, change has occurred throughout the American culture, such as major advances in technology and the way of life. Since the volcanic eruption in 2016, the remaining residents have found new homes and created new lives for further generations

these plateaus are thin and runny. * These plateaus take millions of years to form. Shield volcano - Shield volcanoes form like any volcanoes. They’re spots on the Earth where magma from inside the Earth has reached the surface, and becomes lava, ash and volcanic gasses. Over the course of many eruptions, a volcano builds up layer by layer until the magma chamber underneath it goes empty and the volcano goes dormant. Shield volcanoes are some of the largest volcanoes in the world. For example, Mauna

John Mysliwiec Conversations with the Earth November 29th, 2012 Volcanoes A volcano is a landform that generally is circular in cross-section that is constructed from lava and tephra erupted onto the Earth’s surface, usually the crust. The opening through which the lava and tephra are emitted is called the volcanic vent. Lava is magma that reaches the Earth’s surface. Magma is melted rock at high pressure and temperature. Magma rises because it is initially less dense than the

are pulling apart from each other, forming new crust. This creates a gentler volcano, as there is pure mantle forming the magma. They sometimes appear on a convergent boundary. When the two pieces of land are oceanic and oceanic, and oceanic and continental, volcanoes will appear. This is because you will get a subduction zone, where the denser plate will be forced under, and consequently melts. This then forms a volcano with mixed magma, both pure mantle, and melted earth’s crust, making these more

Located on the Fernandina Island, La Cumbre is a shield volcano and the most active volcano in the Galapagos Islands. La Cumbre most recently erupted in 2009 and its lava destroyed unique flora and fauna of the area, such as reefs and animals such as birds and iguanas. The name “La Cumbre” means “the top” in Spanish, getting its name for its height and placement. The volcano has experienced several collapses of the caldera floor, often following explosive eruptions. Towering at a height of 4,842

2012 To what extent can preparedness and planning mitigate the effects of volcanic hazards? Preparedness and planning can mitigate the effects of volcanic hazards. However there are many other factors that can influence the effects, such as volcano type, severity of eruption, length of eruption, third party influences of which no country can prepare totally for. However these are methods which will reduce the impact. In this essay I will discuss the impacts of a Chilean volcanic eruption which

Fire In The Sky Alexander Cassimaty, Volcano Expert Mount Lamington is a 1,680 meter-high volcano located in Papua New Guinea. Three days of tremor preceded the eruption at Mount Lamington volcano. Landslides, ash emission, glowing volcanic bombs and lightning were seen by the people leaving around the volcano. The paroxysm at Mount Lamington occurred at 10:40 on 21st Jan 1951. A roar was heard 320km away and a catastrophic avalanche ripped apart the

of the Washburn volcano and whatever mountains existed between Mt. Washburn and the Red Mountains. Geologists have identified streaks and thin layers of Yellowstone volcanic ash from as far away as California, Saskatchewan, Iowa, and the Gulf of Mexico. Ash was blasted into the stratosphere circulated around the globe and must have altered the weather worldwide. 2. Which Tectonic plates are present in Yellowstone national park? Yellowstone National park is known as a Super-volcano; due to the extensively
