Assignment 8: Volcanic Hazards Essay Throughout the world there are a variety of natural disasters that occur among the environment on a daily basis. Some may only cause minimal harm, but others could be extremely destructive to the point where it could cause certain deaths and ruination. Among the several natural disasters that are known, volcanic hazards have become one of the most concerning threats here in the United States and in the world. (Myers) This has sparked my interest because it was interesting to learn about how intrusive and troubling volcanoes, explained thoroughly in chapter four of the textbook, can be and how it impacts the planet we live in. Throughout this essay, I will describe different kinds of volcanic hazards, how …show more content…
(Decker) Eruptions then lead to a variety of other hazards such as pyroclastic flows, ash clouds, and mudflows, which is what most likely will affect people nearby the most. Another major volcanic hazard is the release of gasses emitted from fumaroles, which are the openings or small cracks of a volcano. (Myers) For example, an eruption that occurred in 1991 at Mount Pinatubo in the Philippians released a large amount of sulfur dioxide gas, that when mixed with water created a toxic substance called sulfuric acid, which was determined to be one of the factors leading to the damage of the ozone layer. (Myers) Due to the intensity of these hazards, people and the environment suffer from its dangerous …show more content…
For example, cameras, satellite imagers, instruments that measure and detect volcanic ashes, etc. are some of the tools used by volcanologists to monitor and record volcanic activity. (Marie) These are tools that have also facilitated the way the public can keep up with these records, as most of them are published on official websites and newsletters. There are also methods, similar to ones used for earthquakes that are used to follow active volcanoes such as gas and seismic monitoring, which work by detecting rock movement within the crust of the earth. (Marie) Although volcanoes can be highly unpredictable, volcanologists have developed better and newer ways in predicting volcanic eruptions throughout time. In conclusion, I have learned about the different kinds of volcanic hazards, how it affects the environment and humanity, and how advances in technology are keeping people safer from volcanic hazards. It is important to be aware these facts, considering they are real world issues occurring today and will affect the future. Overall, I truly enjoyed researching this topic and gaining more knowledge on the kinds of hazards that volcanoes
Many of us know Mount Shasta to be a beautiful mountain and a popular tourist location in California. However, this mountain is much more than that, this mountain is actually a volcano. Volcanoes come with a number of hazards and a volcano of this size is of no exception. Previous eruptions on Mount Shasta have given us an idea of the power this volcano has and the damage it may do. With this information scientists are able to predict what may happen should another explosion occur.
Although volcanoes are difficult to predict, geologists have made many efforts in order to caution the people of Orting and other surrounding towns of possible lahar slides. Residents have been made aware of emergency response plans and they know the proper precautions to take in the case of a volcanic activity emergency. Sirens have been put in place by the fire department and governing bodies of surrounding communities to detect volcanic activity and warn the community of possible slides.... ... middle of paper ...
Volcanic forecasts are more accurate then earthquake predictions. These predictions are generally forecast in the same way as an earthquake (temperature increases in geothermic waters gaseous concentrations, changes in elevation of land and water etc… Because we generally know where Volcanoes are, we can predict when an eruption may take place.
In conclusion, this powerful event tore the landscape, obliterated the geography, and had a colossal impact on the environment and the way that people observed data. These examples of explosions, mudslides and ash helped make improvements towards the future and understandings of past events. Even though Mount Saint Helens destroyed the landscape, it built a better understanding of human knowledge.
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.
The first time I saw Mt. Rainier for myself, was last summer when my boyfriend and I drove to Washington. It was the most beautiful, peaceful looking mountain I have ever seen. However, underneath it's great beauty, it hides a deadly secret. Mt. Rainier is one of the most dangerous volcanoes that we have here in the United States. One of the reasons it is so dangerous is because of it's great beauty. People enjoy looking at it, and the area that surrounds it, so they have made their homes here. Mt Rainier is not the only volcano I am interested in, in fact this last summer I also went to Mt. St. Helens and Crater Lake. But it is the volcano I chose to research for this paper because it does have so much beauty and at the same time so much power. I already know the basics about volcanoes, how they form, the different types, etc., but I wanted to find out more about what would happen if this great volcano were to erupt, what type of eruption would it be, and how would it affect the people that live around it.
From modern examples and records we know that volcanic activity can set of a chai...
These differences are in the makeup of the volcano, the impact on society, and the eruption itself. Mount Saint Helens, used to be a wonder of the world, but now a damage site of what happened on May 18, 1980. Mauna Loa is a tourist destination and one of the most active dispensers of lava and magma in the world. As shown, these volcanoes can’t be more different. Yet, each volcano has been a culprit to destruction, and have similarities within themselves. This report has expressed many similarities and differences and brought facts and knowledge to the historical eruptions by these impressive and ancient structures of
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
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...
When the reservoir has formed, a substance is collected that will trap the volcanic gases. They form depressions in the ground and it is very hard to imagine the eruptions, explosions, car atrophic proportions that they cause. Super volcanoes produce vast amounts of ash and destruction. There are thousands of normal volcanoes around the world and at least 50 erupt every year. Vast clouds of ash are deafening sounds; it affects the climate on earth for many years and affects the agriculture colour.
Volcanoes can be one of the most destructive forces on Earth. It is estimated that some
The sulfate aerosols cause chemical reactions in addition to chlorine and bromine reactions on stratospheric clouds that destroy the ozone.8 Some ozone depletion is due to volcanic eruptions. Analysis of the El Chichon volcanic eruption in 1983 found ozone destruction in areas of higher aerosol concentration (Hofmann and Solomon, "Ozone Destruction through Heterogeneous Chemistry Following the Eruption of El Chichon"). They deduced that the "aerosol particles act as a base for multiphase reactions leading
Wildfires are catastrophic disasters that destroy everything in their path. “A wildfire (also known as forest fire, grass fire, vegetation fire, etc) is an uncontrolled fire often occurring in wild land areas, but which can also consume houses or agricultural resources.” (Wildfire.) The causes of wildfires are mostly intentional, negligence or accidents and natural causes. Wildfires have three distinct phases: Initiation, propagation, and extinction. This phenomenon affects our ecosystem, such as air and earth. In addition, people who witness this kind of catastrophe in the lower cases they lose belongings as houses or cars, but they can also lose their lives. There are many campaigns that help prevent these phenomena, but they need the help of the entire community. It is very important take care of not cause an accident. Wildfire is a phenomenon very common on these days causing a terrible damage to our environment and we have to prevent its expansion through our help, cooperation and prudence...
