...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. One physical factor which causes differences in a volcanic hazard is the steepness of the volcano. If the volcanoes sides are of a steep gradient then the lava from the volcano would flow must faster than if the sides were a steady gradient. Mount Nyiragongo for example had extremely steep sides, 50 degrees at some points. This, combined with the low viscosity of the basaltic lava, saw lava speeds of up to 60 miles per hour. The hazard of a lava flow in Nyiragongo was much greater than if the volcano had steady sloping sides. The type of lava also influences the hazard, if the lava is rhyolitic then it has a high viscosity due to its high silica content and its low temperature (only between 650-750 Celsius). Therefore it won’t flow very fast, minimising the impact of the hazard, whereas if it is basaltic like Mount Nyiragongo then it will flow extremely fast, intensifying the hazard. The location of a volcano is also a large variable in determining the nature of its eruptions. Volcanoes are generally...

...chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or cause damage to the natural environment or built environment, into the atmosphere. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems. Indoor air pollution and urban air quality are listed as two of the world's worst pollution problems in the 2008 Blacksmith Institute World's Worst Polluted Places report.[1] Pollutants Main articles: Pollutant and Greenhouse gas Before flue gas desulfurization was installed, the emissions from this power plant in New Mexico contained excessive amounts of sulfur dioxide. Schematic drawing, causes and effects of air pollution: (1) greenhouse effect, (2) particulate contamination, (3) increased UV radiation, (4) acid rain, (5) increased ground level ozone concentration, (6) increased levels of nitrogen oxides. A substance in the air that can cause harm to humans and the environment is known as an air pollutant. Pollutants can be in the form of solid particles, liquid droplets, or gases. In addition, they may be natural or man-made.[2] Pollutants can be classified as primary or secondary. Usually, primary pollutants are directly emitted from a process, such as ash from a volcanic eruption, the carbon monoxide gas from a...

...Alternative Energy Sources Geology Many people believe that we must depend on fossil fuels for energy, where as the reality of it is the earth provides an abundance of renewable energy sources. These energy sources can produce enough energy that we would never have to use fossil fuels again. Alternative energy is the use of other energy sources instead of the use of fossil fuels or nuclear energy. Solar power can be used to operate cars and provide electricity to homes and businesses. Hydropower can be used to provide electric power to small towns and cities. Geothermal power can heat up buildings or water to power turbines to make energy. Wind power can be used to pump water and generate electricity. So let’s start with solar power since it is the most known of the group. Energy from the sun is one of the most abundant resources available today out of the alternative group. It is one of the most important of the non-conventional energy sources as well, because it does not pollute the earth. “One of the reasons for this is that the total energy we receive each year from the sun is around 35,000 times the total energy used by man”. (Alternative Energy Sources) One way to capture the sun’s energy is through the use of solar panels made out of Photovoltaic cells, which are commonly called (PV) cells. These panels can be used on homes, businesses, greenhouses, water heaters, traffic lights, or grouped together as a solar power plant. PV cells can transform the sun’s energy...

... nested (like El Piton in Teide), multiple summits (like Shasta), elongated along a fissure (like Hekla). Strato-volcanoes are constructed along subduction zones. Examples of composite volcanoes include Mount Hood, Mount Rainier, Mount Shield volcanoes are huge in size. They are built by many layers of runny lava flows. Lava spills out of a central vent or group of vents. A broad shaped, gently sloping cone is formed. This is caused by the very fluid, basaltic lava which can't be piled up into steep mounds. Shield volcanoes may be produced by hot spots which lay far away from the edges of tectonic plates. Shields also occur along the mid-oceanic ridge, where sea-floor spreading is in progress and along subduction related volcanic arcs. The eruptions of shield volcanoes are characterized by low-explosivity lava-fountaining that forms cinder cones and spatter cones...

This includes land, water, and air. Of all the First World countries, the United States is the most polluting nation on Earth. The United States is ranked seventh on pollution control, by only spending 60% of its Gross National Product to help the environment. As a nation we have spent over 120 billions of dollars a year on research and development. The majority of the cost incurred has come from Environmental Quality, our country has consumed over 98 quadrillion Btu of energy in the year 2000 alone. Americans generate five pounds of solid waste every day, creating one ton of solid waste each year. In an average day in the United States, we throw out 200,000 tons of edible food and have thrown 1 million bushels of litter out of our automobiles. The main human contributor for pollution are landfills. It is possible that land pollution can contaminate the air and/or the water. Water pollution is the action of environment contamination...

...southwest Italy near Bay of Naples. Herculaneum was a waterfront town situated on the coast of Bay of Naples 7km west of Mt Vesuvius, while Pompeii was slightly inland on the Sarno river, 9km southeast of Mt Vesuvius. Both towns were linked to Rome through sea and land routes. Natural features Campania was a fertile plain with two main rivers. Nearby there was a 15km wide series of craters, where pools were filled with boiling mud and vents, from which sulphur and steam could escape. The towns were popular because of their rich volcanic soil, coastal area for fishing and trading area. Resources of Campania The production of olive oil was used for cooking, and as the basic ingredient for perfume. Wine, wool and textile productions took place, along with the fishing industries including the production of fish sauce. There were fruits such as peaches, apricots, lemons & vegetables like cabbages and onions, and volcanic material was used for building and paving roads. Plans and streetscapes of Pompeii and Herculaneum ▪ streets of Pompeii vary greatly in width from 2.4m to roughly 7m ▪ streets & roads divide towns into neat rectangular blocks- called insulae ▪ insulae blocks had 1-12 dwellings with houses, apartment blocks, shops ▪ streets were paved with large Vesuvian lava blocks ▪ either side of most streets had a raised sidewalk, usu about 33cm high ▪ streets were usu raised in the middle so water would run into gutters and footpaths sloped...

... organic materials, and particulate matters. Automobile is the greatest contributor to our air pollution. Various living organisms, such as animals, humans, and plants are at risk. Plant life is critical to keep our air uncontaminated. Human daily activity is the prime impact of both negative and positive effect to air quality. United States is suffering from major air pollution because of the mixture of immense population use of automobiles and manufacturing industries. Motorized vehicle emits substantial amount of carbon monoxide and nitrogen in to the air every day. Manufacturing industries, such as power plants and other facilities, release ten times more of particulate matters and sulfur oxide than motorized vehicles. In contrast, the positive effects humans have to offer are taking a few initiatives to redeem their mistakes by inventing non conventional fuels such as biodiesel, batteries and fuel cells, and other biomass resource. This proposal is to establish a mitigation plan to discuss the benefits and challenges of air pollutions. Furthermore, this devise strategy will encompass government and societal support to enhance the air quality we breathe. “The atmosphere is a complex, dynamic natural gaseous system that is essential to support life on planet Earth.

...warming is an undeniable fact, which proves that our planet and its climate are in a big trouble. Global warming affects all areas of our life including; politics, economics and a social sphere. The study of global warming includes many sciences in order to examine what causes global warming and try to find possible solutions to reduce the impact of our civilization on the planet. An interdisciplinary research in this field is important, because global warming is caused by many factors and has an impact on different spheres of our life. For example, climate science is aimed to investigate the changes caused by global warming. Geology examines the impact of human activities on climate. Economic science helps to understand economic benefits and material losses caused by severe weather conditions taking into account results obtained by climate science and Geology. Economic science inquiries into and develops measures to reduce negative impact of economic activity on climate and global warming. Taking into account the information mentioned above, it is evident that an interdisciplinary research is crucial, because one scientist is unable to solve the problem of global warming without any sort of collaborative effort with other disciplines. Natural disasters such: hurricanes and tornados are the result of global warming. In Recent years, hurricanes have become a great problem for many coastal villages and towns around the world. Scientists say that hurricanes are cause by heated water and...
