The most certain threat to La Plata County and the City of Durango is Non-WUI Wildfire, but the magnitude is limited. The highest risk to La Plata County and the City of Durango is WUI Wildfire which also has the most catastrophic magnitude. The next highest risk to both is a severe flood. These risks are also have a high likelihood of being exacerbated by technical hazards such as extended power failure, significant communications/infrastructure break-down, major failure of pipeline or energy

Physical Science II Lab Exercise 10 Pollution of Earth’s Atmosphere Earth’s atmosphere is a dynamic, complex, yet fragile system. Unfortunately it is not treated as such. Pollutants created in the environment by natural processes and humans have a negative impact on our world. Pollution is not a new concept that just became popular in this century. Over hundreds of years, people have taken notice of pollution and its effect on the quality of life. One of the biggest events being the industrial

Air Pollution Smog hanging over cities is the most familiar and obvious form of air pollution. But there are different kinds of pollution, some visible and some invisible, that contribute to global warming. Generally any substance that people introduce into the atmosphere that has damaging effects on living things and the environment is considered air pollution. Carbon dioxide, a greenhouse gas, is the main pollutant that is warming Earth. Though living things emit carbon dioxide when they breathe

Granite is a common type of felsic intrusive igneous rock, which is found in the continental layer of the earth’s crust. Granite is formed underground by the cooling of magma. Deep inside the earth, past the mantle layer, there is a deep layer of molten rock. The molten rock is formed when naturally occurring radioactive elements inside the ground break down and decay. The reaction of the decaying material frees large amounts of heat, melting the rocks around it. As geological events happen, like

Yellowstone’s Petrified Tree If you do not feel like taking a grueling all day hike to reach a petrified forest, Yellowstone’s petrified tree might be the thing to see. It is a short drive from village of Tower-Roosevelt and can be seen from the road, just off Yellowstone Grand Loop Road. Fifty million years ago the tree was a living redwood like the redwoods of California. At that time what is now Yellowstone had a warmer, almost subtropical climate, and rain was frequent. “Petrified”

THE YELLOWSTONE SUPER EVENT Approximately, every 600,000 years the Yellowstone Caldera explodes changing the face of the North American continent. It has been 640,000 years since the last event and geologists say that it is not a matter of if, but when. Recently a number of earthquakes and extreme occurrences in the Yellowstone area and what is called the Ring of Fire suggest that Yellowstone might be coming active. For instance, according to the Huffington Post, July 11th, 2014, “A

A hazard can best be defined as a 'situation that poses a level of threat to life, health, property or the environment'. The overall impact of earthquakes as a natural hazard varies greatly from one place and time of day or year to another. As do the types of hazards, which are classed as either primary or secondary hazards. Primary hazards are created by the direct seismic shaking of an earthquake; this could include liquefaction, slope slipping and tsunamis. These primary hazards can in turn trigger

Name Lecturer Course Date Acid Rain Introduction Acid rain, also called acid deposition refers to the deposition of wet or dry acidic materials from the atmosphere on the surface of the earth (Hess, Darrel, and McKnight 172). Although in most cases Acid deposition is associated with rainfall, sometimes the acidic pollutants in the atmosphere can fall with hail, snow and sleet. Acid rain occurs when the oxides of various compounds dissolve in water in the atmosphere. One of the compounds supplying

Choose either the Philippines or California and explain why it is considered a disaster hotspot. (15 marks) A disaster hotspot is a place where they not only have a high vulnerability, but also a number of different hazards: hydro-meteorological and geophysical. The Philippines is vulnerable to disasters because they’re a lower middle income country, with majority of the people living in poor conditions/poverty and near the coast. This implies that they lack sufficient infrastructure to protect
