Volcano And Its Effect On The Volcano

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

A hazard is a situation that poses a level of threat tolife, health, property or environment. The level of hazard posed by different volcanoes can very greatly, from a weak eruption with minimal impact that causes little damage, to a voilent and life threatening explosion. Most of the sixty-plus volcanoes that erupt each year are low risk, however a combination of factors can cause a volcano to be a serious hazard. The factors causing these variations will be explained in this essay.

Volcanoes can be found throughout the entire world and are formed when there is a rupture in the mantle of the Earth's crust. This effect allows the output of volcanic lava, ash, and various types of gases. These tectonic plate breaks are normal, the planet Earth is divided into 17 tectonic plates and consistently move against each other forming shifts from low to high intensity. It can cause displacement of earth or water.

Volcanoes are one of the most destructive, yet, most beautiful things on Earth. They can make a famous city choke in its own ashes in one day, like Pompeii. Or they can turn a once damaging mountain into a graceful and peaceful home for new life, like Mount St. Helen’s. All volcanoes are unique, and no two are the same. Some erupt differently than others, some look different than others, and all are located in different spots all over the world. I learned this while completing the project and the five volcanoes I researched are examples of my discoveries. The five volcanoes I researched were Mount Hood, Mount Mageik, Long Island, Mount Muria, and Las Pilas.

Mount Vesuvius, like most volcanoes was created through the interactions between continental plates. Mount Vesuvius was formed 17,000 years ago through the convergence of two tectonic plates, the African plate and the Eurasian plate. Vesuvius is located above a subduction zone in which the African plate is being subducted by the Eurasian plate (Ball). The African plate has been subducted at a rate of about one inch every year. This type of interaction between converging plates is responsible for creating volcanoes (Figure 1). This created a submerged deep ocean volcano in the Bay of Naples. Later, Mount Vesuvius emerged from the ocean as an island. However, over time it was connected to the mainland due to buildup of deposits from its eruptions.

To begin, a volcano is a mountain with an opening in the top or side that sometimes sends out rocks, ash, lava, in a sudden eruption (Merriam-Webster, n.d.). A volcano erupts when pressure builds inside the mountain. Magma, lava while it is inside the volcanoe, pushes through the weakened crust. When this built up pressure is released, Earth’s plates move causing a volcanic eruption. Also, dangerous flows of steaming lava can reach up to 2,000

A volcano is a mountain built when magma rises from Earth's interior to the surface of the Earth.Volcanoes erupt when the pressure of the melted rock inside becomes so high that it blows through the solid surface of volcano. This explosion leads to many economic difficulties just like it did when Mount St. Helen exploded. It is a devastating event and clouds of ash, dust, and gases flowed into the environment. These fumes can be difficult to breath in and the damage it can cause wildlife is also

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.

People are afraid that this volcano will explode and are scared that something bad will happen. People are moving out of their house to a safe place to live and were forcedd to evacuate about 2,000 residents. Some people choose to move out to a safer place and away from the dangerous area. Residents are involved in this tragic event, stay in not an option for anyone dangerous gases are released and can kill anyone human inhale this dangerous gases. The event is about a volcano that is about to explode from so much pressure being built up. This event is happening in Hawaii were people want to move out. It's happening in May 4 at 11:40 a.m. The cause of this event is happening because pieces of rock are falling off to the volcano and that is making pressure built up and has to escape some we're including magma is falling below sea level. This is one of the most active volcano in the world. It will continue for 100 years no surprises this is happening because it has happened over millions of years.

A few kilometers from the city of Mexico is the Popocatepetl volcano. It is one of the most active volcanoes in the territory of Mexico. That has had approximately fifteen explosions since 1519. The authorities of Mexico designed the volcano warning light of Popocatepetl. It is important to be prepared in case of an eruption. Residents living near the volcano should ask scientists how to be prepared in case of an eruption. What does it mean the volcanic alert traffic light? Where are the closest shelters? What do I need to have ready to take with me?

The Hawaiian volcano is a shield volcano; they are the oldest continental regions of earth. They may even be the remains of ancient shield volcanoes. A shield volcano is tall and broad with flat, rounded shape. The Hawaiian volcanoes are built by countless outpourings of lava that advance great distances from a central summit vent or a group of vents. Extensive study of the Hawaiian Islands revealed that they are constructed of a myriad of thin basaltic lava flows averaging a few meters thick intermixed with relatively minor amounts of pyroclastic ejected material. During eruptions these outpourings help keep these volcanoes safe. When these volcanoes erupt lava fountains out form the volcano and is hot liquid lava is thrown into the air but usually not very high. The lava normally flows easily, and does not explode. These volcanoes also only explode if water some how gets into the vent. Mount St. Helens is composite volcano, which are also known as strato- volcanoes. They are tall, symmetrically shaped, with steep sides, sometimes rising 10,000 feet high. They are built of alternating layers of lava flows, volcanic ash, and cinders. The large and generally cone-shaped volcanoes form along plate boundaries called subduction zones where one of the earths plates melts as it falls back into the earth`s mantle. The eruptions are called explosive, and effusive, because vast amounts of gasses are thrown into the atmosphere, and the lava explodes and is vicious.

First there are tectonic plates that collide together that will cause an earthquake which can make the volcano erupt.

Volcanoes are mountains that have lava inside. Hotspots are a reas with tectonic plans with magma pushed up the top! pressure builds in the earth we measure them by a seismographs.

This is only a general overview of the inner workings of volcanoes and their eruptions. For more infomation, visit Volcano World -- The Premier Source of Volcano Info on the Web.
