Natural Disasters : A Volcanic Eruption

Volcanic activity happens across the surface of the globe therefore bringing hazards to every affected area. A hazard is any source of potential damage, harm or adverse health effects. A volcanic hazard is any threat to life and infrastructure due to volcanic activity and related situations such as a landslide near the volcano. Volcanoes can be very dangerous and therefore present many hazards towards both people and land. They have the ability to kill and destroy, ruining livelihoods and destroying large land masses. The extent of the hazard can differ depending on how prepared an area is for an eruption and how much planning has gone behind

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.

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.

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.

A hazard can be define as something which poses a level of threat the life, health, property or environment, a volcano can compromise all these things through the many hazards volcanoes presents. Such as lahars, flash flooding, landslides, pyroclastic flows, ash clouds and many others. There are factors which can influence the severity of the hazard and cause differences in them and can be classified into different categories, such as physical, economic, political and social.

Volcanoes are in fact important because without volcanoes the atmosphere wouldn’t have its oxygen rich properties. Many of years ago, Earth’s atmosphere was swarm with rock-forming minerals of the earth 's crust. During earlier volcanic eruptions many gasses enters into the earth atmosphere. Carbon dioxide, water vapor and many other gases

What is a volcano: A volcano is a mountain created by the earth. It also creates a hole where molten rock (lava) erupts. A volcano is filled of magma but when the magma erupts and is out of the volcano it is now called lava. When a volcano erupts it fills the air with lava fragments. A volcano can cause a lot of destruction like tsunamis, flash floods, mudflows, rockfalls, and earthquakes. Most volcanoes are located where the tectonic plates meet. Most

Usually, many earthquakes in succession can warn of a volcanic eruption. Warning systems for volcanoes are based on the possibility of a hazard. The volcanoes are classified based upon the likeliness of an eruption. An active volcanoe is currently erupting or expected to erupt in the near future. Dormant volcanoes are inactive, but they are likely to erupt sometime in the future. An extinct volcanoe is unlikely to erupt again. Even though a volcanoe is not expected to erupt, it could suddenly become active. Volcanoes are unpredictable because almost any of these mountains could erupt again. There is no current way to ensure that a volcanoe will not erupt. To prepare for a volcanoe families should have an emergency supply kit that includes food, first aid kits, and other supplies. Also every family should have a plan to stay safe during any natural disaster. The best way to stay safe from a volcano that is likely to erupt is to evacuate (Anderson, 2012). 260,000 have died within 300 years from different volcanoes and their aftermath (National Geographic, 2016). Volcanic eruptions can be accompanied by other natural disasters including mudflows, flash floods, rock falls, acid rain, and tsunamis. Devastation from a volcanoe can stretch for hundreds of miles (Anderson, 2012). Hence, volcanoes are unpredictable disasters that everyone near a volcanoe should be prepared for, even if it is not expected to erupt

The eruption of Mount Vesuvius in 79 AD was a pyroclastic event discussed in greater detail over the course of this essay.

In these eruptions, instead of the mixture of gas and ash flowing upwards, it flows outwards and hugs the ground. These eruptions are extremely dangerous.

How volcanoes affect people and environments? A volcano is a mountain or hill having a crater or vent through which lava, rock fragments, hot vapor, and gas are in. Volcanoes can change the weather. They can cause rain, thunder and lightning. Volcanoes can also have long-term effects on the climate, making the world cooler.

Volcanoes and Earthquakes are two of the most intriguing natural disasters that can occur on earth. Unlike hurricanes and tornadoes, they can awaken at almost any point in time throughout the year. These two natural disasters are also different from others because they occur on the layers of the earth itself. Volcanoes, while large to us, are actually small, conical patches of earth that spurt and ooze hot molten lava from the core, and can destroy areas of land triple their size. Earthquakes, on the other hand, are severe jolts felt on land due to the movement of earths tectonic plates. Some may describe earthquakes as being similar to riding a bike down a flight of stairs. The impact of an earthquakes can take down even the largest buildings and strongest structures. All natural disasters can have damaging effects on land, some more than others, and all can be measured or predicted in different ways. Although earthquakes and volcanoes are similar to each other, the two are still very comparable. A few of these similarities and differences include the cause of their occurrence, and how their occurrence impacts the environment.

On the 15th June of 1991, the second largest volcanic eruption of the twentieth century took place on the island of Luzon in the Philippines, 90 km northwest of the capital city Manila. It was also, by far, the largest eruption to affect a densely populated area. Mount Pinatubo, a stratovolcano, is part of a chain of volcanoes along the Luzon arc on the west coast (refer map). The arc of volcanoes is due to the subduction of the Manila trench to the west. The mountain has a very huge eruptive history. It was known to be thermally active and had been explored as possible geothermal energy resource by the Philippine National Oil Company. Mount Pinatubo is among the highest peaks in west-central Luzon. Its

This paper will discuss the differences between two different natural and man-made disasters. The disasters that will be discussed are Hurricane Katrina and the Deepwater Horizon oil spill. Additionally, this paper will look into the specifics of what constitutes a natural and man-made disaster. Specifically, this paper will look into each disaster to include the events surrounding them; the risks; and the assessments. Furthermore, this paper will look at some of the details of each disaster and why there was so much devastation. Finally, this paper will look at a few similarities, but mainly the differences between the two, and how the effects of each still linger today.
