Volcanology

A volcano is a special type of mountain. The mountain opens at the top. Beneath it is a pool of melted rock, or magma, below the surface of the Earth. When certain kinds of changes happen, volcanoes can erupt. This means that the gases and melted rock below shoot up through the opening and spill over as lava. Eruptions can lead to lava flows, falling ash, mudslides, and much more. How do volcanoes form? Volcanoes form when magma deep within the Earth makes its way to the surface. When the…

Volcanoes exist all around the world. A volcano is a break in the Earth’s crust that produces lava, gases, ash. Some volcanoes are active and some volcanoes extinct and dormant. Magma usually forms 30 to 120 miles beneath Earth’s surface. Most volcanoes are tourist attractions and most people like to climb them and to live near them to produce some heat to there house when the people don't have any heat. Villarrica is located in the country of chile. Villarrica has a 4 star warning and…

The Mount Pinatubo Eruption in 1991 is largely regarded as the second largest volcanic eruption during the 20th century. Before erupting in 1991, the volcano had been dormant for around 400 years. During the years of 1990 and 1991, there were many events that led to the eruption of Mount Pinatubo. A magnitude 7.8 earthquake struck 100 kilometres north east of the mountain on July 16, 1990. This event is contributed to the reawakening of the dormant volcano which triggered many small…

In this film, the eruption of the once dormant Mount Vesuvius in 79 C.E. is discussed. It is a volcano that is right between two tectonic plates, so when an earthquake shook it, it finally exploded. The eruption was one that was 1000 times more powerful than the bomb we dropped on Hiroshima. The town of Pompeii was located just below the volcano, and did not stand a chance against its wrath. At the end of Vesuvius’s eruption, Pompeii was covered in sixteen feet of ash. About sixteen centuries…

Hawaii’s Kilauea versus Mount Fujiyama Ever since I was a little girl I have always been fascinated with volcanoes. How do they work? How hot is the lava exactly? Can you travel down into the funnel of a volcano, and if so how and will you survive? And do all volcanoes function the same way? As a child, we never understood that the beautiful hot magma that flows from the volcano is dangerous and burns everything in its path. Two volcanoes that have always caught my eye is Hawaii’s Kilauea and…

Would people recognize the difference between “active volcano” and “Holocene volcano?” Well there is no difference, people just use the term “active” wrong. Scientist say that, “...it is misleading to restrict “active volcano” to recorded human memories: we prefer to add another identifying word (“historically active” or “Holocene volcano”).” People are probably confused on what these terms actually mean because no one would see the difference or wouldn’t care. Volcanoes are very old, they…

The purpose of this paper is the explain a natural phenomena, Axial Seamount. Even if the reader has no knowledge of Axial Seamount, they will be able to fully understand the content of this paper. They will learn facts about Axial Seamount such as what it is, on what plates it is located on, what landforms are around it, etc. Axial Seamount is an underwater volcano located in the Northeastern Pacific Ocean, about 483 kilometers (300 miles) off the coast of Oregon. Because its frequent volcanic…

There are over 1500 active volcanoes is the world. Sometimes we do not know when a volcano is going to erupt, but most of the times the volcano itself gives early signs of eruption. Some of those signs are small earthquakes beneath the volcano, swelling or increase heat and gases coming out of the volcano. A volcano is a mountain or hill, having a crater or vent where lava, rock fragments, hot vapor, and gases are being released from the earth's crust. One of the many active volcanos in the…

There are a total of ten different landscape regions located within the Pacific Northwest. The rocks that are within each region provide the foundation for the landscape within the region. The study of the rock located in the region tells us about the geologic past and provides insight on the materials and processes from which the landscape was formed. I will briefly discuss each of the areas and provide insight on the types of rocks in which they are formed from. We will start with the Basin…

my paper I will be giving information on how often do volcanoes erupt. First,I will explain how magma can trigger volcanic eruption. Next, I will discuss how buoyancy can also trigger a volcanic eruption. Finally, I will predict how pressure from gases in the magma and magma chamber can cause a volcanic eruption,and give some more details about my volcano. It depends on the volcano to erupt oftenly. Some volcanoes erupt very often (and some like Kilauea almost never stop). On the other hand,…
