This beautiful planet called Earth comes with a fatal price, natural disasters. One of the most destructive natural disasters out of the many that Earth faces, are volcanoes. When volcanoes strike, everything from people to the environment are affected in both negative and positive ways. One of the biggest effects that volcanoes have on this planet, is to its environment. When volcanoes erupt, they produce rock and ash that eventually settle into the surrounding area. As a result of that new layer over a part of Earth, plant and animal life can immediately vanish because of the damage done to the environment. No land around the volcano will be untouched after a volcanic eruption occurs as the article “How Many Active Volcanoes Are There?” …show more content…
A negative effect on people as a result of volcanoes, is that people can lose everything to a volcano, like their personal belongings, homes, and even lives. Volcanoes leave mass destruction in their wake, for example like the eruption of Mount Vesuvius 10,000 years ago. Hundreds of lives were taken and homes destroyed in this catastrophic event like with many volcanic eruptions. People are never safe from volcanoes because they are constantly erupting as the article “How Many Active Volcanoes Are There?” states that about 20 volcanoes are erupting this very minute. On the flip side, volcanoes can positively affect the people in the surrounding areas. The ash and rock that volcanoes leave behind after they erupt, sink into the soil and make it rich in minerals. This richer soil has a positive effect on people because it can support plant life even better and result in more crop growth; for example, “The soil is so rich that farmers often plant different crops intermingled with each other to maximize the use of every square inch available,” (McDonaugh 61). If farmers are able to plant even more crops, they can have a higher income from consumers and are able to provide themselves even better. As for the consumers, volcanoes have a positive effect on them in this aspect because there will be something for them to put on the tables for
Easter Island, or as some would call it “Rapa Nui,” was one of the most isolated islands in the world that was inhabited by humans. The island does not have a lot of wood and other resources and yet, when the first travelers discovered the island, it was full of huge carved stones statues. Around the twentieth century they discovered that when the first settlers came to the island, it was rich with resources and bountiful land. The first settlers also had a complex society with a hierarchy and sophisticated religious rituals. According to Barzin Pakandam, from the London School of Economics, The inhabitants of Rapa Nui are the descendants of a group of Polynesian settler colonists. It was estimated that at first there were only twenty to thirty settlers that arrived on the island. They arrived on large conjoined sea-faring canoes built for long distance travel. The settlers brought many traditional Polynesian staple foods with them including chickens, rats (considered a delicacy), taro, yam, sweet potato, bananas, gourds, paper mulberry, turmeric, and arrowroot. Archaeologists and historians assume that the origins of the Islanders are the archipelago chain of the Mangareva’s (Pakandam, 2009, p. 9). First, researchers were interested in how these settlers carved the statue and transported them all over the island, but they changed their focus to the theories of how the islanders was driven to collapse. The researchers came up with different theories as to why the islanders were driven to collapse and they are still debating which theory is the right one.
Yellowstone is a national park covering 3,468 square miles in Wyoming, Idaho, and Montana and it is elevated 8,000 feet from the ground on a plateau. But is there still present volcanic hazard in Yellowstone? The park is covered with over 10,000 geysers, hot springs, mud pots, and travertine terraces, perhaps caused by a ?hot spot? that it overlies. A violent history suggests equally as devastating future volcanic activity, underground forces are causing the landscape to change and geysers to become more active. The real question is, if a super volcanic explosion took place, would human life exist as we know it ever again?
...815 eruption of Mount Tambora. With over 70,000 deaths and a rating of 7 on the volcanic exclusivity index, this eruption is one of the largest in recorded history. Not only did this volcano cause destruction in Indonesia but the consequences were further felt around the world, as volcanic ash and sulphuric gases were dumped into the stratosphere causing a global climate shift. Dark clouds covered the sun, and dramatic weather changes ensued. Flash floods frequently occurred wiping out a great deal of crop eventually causing prices to skyrocket. Disease began to spread due to malnourishment and unsanitary living conditions. Eventually these consequences subsided and citizens began to migrate towards Mount Tambora once again. Today the government has placed seismic sensors are set up in the most volatile areas to ensure preparedness in the event of another volcano.
Volcanoes have always been a mysterious wonder of the world. Volcanoes have shaped the landscape and the very ground that we all live on. People have written stories of their disastrous eruptions, and painted their marvelous shapes on canvas. The essay will outline some of the more famous volcanoes and how they have impacted are history. Mount Vesuvius that destroy the great city of Pompeii, Krakatoa they spewed deadly ash on small village town, and Mount St. Helen, the only volcano in my own country to every erupt during my own time period.
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
Ancient Hawaii, an old civilization. This has shaped modern Hawaii and our lives. From its climate, politics, education, religion, art and architecture, technology, economics, and social live. The ancient Hawaiians are fascinating.
It is not difficult to see volcanoes flustered imagine the devastation and destruction caused by the lava if it hit the urban areas. The effects are not limited
Volcanoes can cause damage by spewing lava, but earthquakes before the eruption can also cause damage. These earthquakes open fissures and let magma out to the surface. When the magma exits these fissures, streams of lava up to hundreds of feet can shoot into the air. The picture below shows the lava erupting from the fissures created by the earthquakes in...
Within a thousand kilometres falling ash, lava flows and the utter explosive force of the eruption would kill practically all life. Volcanic ash would cover places as far away as Iowa and the
Volcanoes can be one of the most destructive forces on Earth. It is estimated that some
Plate tectonics is the theory that landmasses on tectonic plates are in slow constant movement due to convection currents in the mantle. Plate tectonics, or the movements of plates above the lithosphere (the most upper layer of earth's crust) can cause divergent, convergent,and transform boundaries.A boundary the way two tectonic plates collide. is Continental plates are plates that the continents are formed on. Oceanic plates are plates that the ocean covers, and the oceans form on top of these plates. Convergent boundaries and divergent boundaries are ways that these oceanic and continental plates interact with each other. Landforms are formed at boundaries. The landforms formed at boundaries depends on the type of plates that collide, and
When people think of geology, they usually think of rocks and fossils. However, geology is actually a very large field of study. The knowledge of geologists ranges from rocks and fossils to the moon and other planets (Hammonds 7-8). Geologists use a variety of subjects in their work, but the sciences and math are the most important. Some of the sciences geologists study are physics and chemistry (12). English is also a subject that geologists use when communicating with other scientists, the media, and the public (12) . Because of these tasks, it is important for geologists to have a wide knowledge of these different subjects.
Many of the farmers do not own their own land and have to rent. A great portion of individual harvest are used to pay landlords. Typhoons, monsoons and volcanoes are among the natural disasters which greatly affect farmers in this region. There are 37 volcanoes in the Philippines 28 of which are active. Three of the most known volcanoes are found in the northern island of Luzon, Mount Pintaubo, Mount Mayon, and the Taal volcano. In 1992, although its citizens had many reasons to hope for a brighter future, the Philippines was a nation plagued with many economic and political problems. These problems had been aggravated by a series of natural disasters. In July of 1990 in northern Luzon a massive earthquake struck. Later that year there was a devastating typhoon in the central Visyas. Subsequently, the Mount Pinatubo volcano in Central Luzon erupted in early June of 1991. The eruption covered the surrounding countryside with molten ash and caused serious damage in the region.
When a volcano erupts, the focus is particularly on the consequences that take place near the volcano, such as weather conditions, the impact on nature, and the people who are affected. The noticeable changes that take place after a volcanic eruption includes the decrease in the temperature, natural disasters, such as tsunamis, droughts, and hurricanes, and the air pollution, which can be harmful to plants, animals, and people.
