Volcanology

Yearly, there are fifty to sixty volcanoes erupted. Within the year, two tsunamis devastate, and several million earthquakes befall upon the planet. These are geoprocesses, all of these affect Earth’s surface and the inhabitants thereof. Earth’s surface changes through geoprocesses including volcanoes, earthquakes, and tsunamis. Firstly, volcanoes are one example of geoprocesses that affect earth’s surface. Volcanoes happen when tectonic plates sink down into the mantle, made up of molten rock,…

“Dante’s Peak” demonstrates the volcano as its star, stealing the spotlight from the obstinate grannies, and the romantic relationship between the heroic volcanologist and the town mayor. The film starts by introducing the terror of how destructive, volcanoes can be. There are two main activities that are associated with this eruption, the bombs, and the ash fall. The introduction, transitions to Dante’s Peak, which is a Composite volcano (Stratovolcano). Dante’s Peak starts indicating signs…

Lassen Volcanic’s geology is very interesting. The terrain has been influenced from many different natural occurrences from 25,000 to 18,000 years ago. Referring back to the May 22, 1915 eruption, the active volcano created a great deal of devastation and depressions; known as the Devastated Area. The devastation caused has an area of three square miles. Volcanoes are common at Lassen. In fact, Lassen is home to all four types of volcanoes, which are shield, cinder cone, plug dome, and…

The thought of standing directly above thousands of kilometers of rock and magma in motion is quite unsettling. But, the anxiety quickly fades because we realize there is nothing to fear in Iowa when it comes to volcanos. 1630 B.C. Santorini, Greece, however, is a completely different story. Not only was the Santorini eruption one of the biggest in Earth’s history, but it quite literally changed the face of the earth and created the infamous myth of Atlantis. Santorini is volcanic small island…

Volcanoes In this documentary, it starts off with the Ring of Fire. This consist of 75% of the world's volcano which is 452. The Ring of Fire is 25,000 miles all around, mostly shaped like a horse shoe. Volcanoes can have different way of how the lava runs. Dr. shows comparing to honey and peanut butter with how the lava can run down the volcano. The lava builds us over the side of the mountain. The doctor also explains that the lava can be very thick that it hold pressure. The pressure…

Seismologist with the United States Geological Survey are usually the first to arrive in volcanic areas, to predict volcanoes eruptions and to alert people so they can get evacuated safely. One problem with the predictions is that the size and direction can’t be predicted. With the new technology and equipment, it's becoming easier to predict volcano eruptions correctly. In 1991 Mount Pinatubo in the Philippines erupted causing many tribes to evacuate their homes. Researchers from the…

As you’re reading this, 20-25 volcanoes are erupting, spreading it’s volcanic ash everywhere. Is this good for our environment? How do volcanoes affect people and our environment? Though, volcanic eruptions do spread volcanic ash which is good for plants. Those deposits are filled with minerals, but unfortunately do not become immediately available to the plants. Where the volcano is located, it can sometimes take up to about a thousand years for the ash and rocks forms a rich, good soil. But,…

Help!The floor is lava! Being a kid did you ever imagine that the floor was hot, bubbly lava? Well did you ever realize that there is a place on Earth where the floor is actually made of lava? Sounds amazing does it not, well we could visit it we just need your approval. This astounding vista is called Lava Beds National Monument and we should visit it for many reasons. Ok class here you can see the amazing Fern Cave. One reason that we should visit this great wonder is that it will help…

The Mid-Atlantic Ridge is in between the African Plate and South American Plate. It lies in between these two plates that are moving away from each other slowly. Although as a result of the separation of the two plates earthquakes occur and magma comes out making new crust. The magma comes out from a series of volcanoes that cool to make new crust. Crust closer to the rift is newer than the crust farther from the rift. The splitting of the African and South American Plate makes a divergent…

There have been many volcano eruption occurred in New Mexico. Through these eruption we can make a prediction of what will happen in the future. I look at the Figure V1 that shows the location, age, and composition of volcanoes and volcanic rocks in New Mexico. Figure V2 shows the histogram of ages for volcanic rocks in the Jemez Mountains. Figure E1 shows the important large-scale tectonic features. After looking at Figure VI and V2 i noticed there is relationship between varies Volcano…
