    Natural Disasters

    1202 words - 5 pages

    INTRODUCTION A natural disaster is the consequence of a natural hazard (e.g. volcanic eruption, earthquake, or landslide) which affects human activities. Human vulnerability, exacerbated by the lack of planning or lack of appropriate emergency management, leads to financial, environmental or human losses. The resulting loss depends on the capacity of the population to support or resist the disaster. his understanding is concentrated in the formulation: "disasters occur when hazards meet vulnerability". A natural hazard will hence never result in a natural disaster in areas without vulnerabili

    Earthquakes Vs Tsunamis

    1007 words - 5 pages

    Earthquakes and Tsunamis have more in common than causing catastrophic disasters. However, they have their many differences. By definition, an earthquake is the result of a sudden release of energy in the Earth’s crusts that creates seismic waves while a tsunami is a series of waves created when a body of water such as an ocean, is rapidly displaced. Although earthquakes and tsunamis are different because of their causes they are both similar do to the fact both cause major damage and how often they occur. Both of nature’s wraths are synonymous to major damages including homes, lives and ec

    Geology and communication are generally not considered closely related subjects. Geology, the science devoted to the study of the Earth and the rocks that compose it, and communication, the exchange of thoughts, messages, or information to another, as by speech, signals, writing, or behavior, are obviously on different sides of the spectrum from one another. Though communication seems unnecessary in this field, as it is difficult to converse with a rock, in actuality, communication is an integral part of a geologist’s daily work.

    Disaster risk reduction 1. Overview 1.1 What is disaster risk reduction? Disaster risk reduction is a cross-cutting approach which seeks to renew the way we think about both development programming and emergency responses which achieve lasting improvements in the lives of people most vulnerable to disasters and reduce the links between disasters and poverty. Poverty and disasters reinforce each other. The poor are more vulnerable to disasters, and disasters in turn can cause increased poverty. The impacts of a disaster can reverse improvements made through development, sending co

    Introduction With recent disasters involving tsunamis and earthquakes, along with other disasters, people begin to wonder if these are related. This is a big question because it was first thought that this was just coincidence, with no relation between the disasters. With more and more instances of situtations like this, scientists began to wonder and investigate. Earthquakes can devistate cities and maybe even countries, but what makes them so dangerous and why are people so afraid? So here is the big question: Are earthquakes and other natural disasters related? Mass amounts of dat

    Earthquakes Earthquakes are one of the numerous natural disasters that humans experience on the planet earth. They are caused by plate movement on the crust of the earth when tension between the rocks causes them to slip therefore creating seismic waves. Earthquakes happen beneath the earth’s surface all the time however, most of the tremors are too small to be felt on the surface. Nevertheless, sometimes large quakes do occur and are felt by people on the surface. Some are just shakes that a few seconds that do not cause much damage and are overall just frighten people.

    Naturally occurring earthquakes Fault types Tectonic earthquakes will occur anywhere within the earth where there is sufficient stored elastic strain energy to drive fracture propagation along a fault plane. In the case of transform or convergent type plate boundaries, which form the largest fault surfaces on earth, they will move past each other smoothly and aseismically only if there are no irregularities or asperities along the boundary that increase the frictional resistance. Most boundaries do have such asperities and this leads to a form of stick-slip behaviour. Once the boundary has

These forces are constantly affecting the surface of the Earth, forming mountains, valleys, ridges etc. When the energy stored within the Earth is suddenly released, for example by shearing movements along faults in the crust of the Earth, an earthquake results. The area of the fault where the sudden rupture takes place is called the focus point or hypocenter. The point on the Earth's surface directly above the hypoce

    Discuss if volcanic activity affects climate change. Volcanic activity generally lowers the global temperature due to its emissions during eruptions, thereby influencing climate change (Wikipedia: “Climate Change”, n.p.). However, its impact on climate change is small as compared to other causes, mainly human activities. A climate change is an extended period of alteration to weather events, indicated by a global variation in average surface temperature and precipitation (Wikipedia: “Climate Change”, n.p., Adler et al., n.p.).

    Volcanoes A volcano is an opening in the earth’s crust through which molten lava, ash, and gases are ejected from. The volcanic eruption occurs when the magma reaches the earths’ surface. But when the eruption is made not all of the volcanic eruptions are explosions. When the volcanoes erupt there is build up deep within the earth which eventually causes the hot magma to rise onto the surface of the earth, causing an eruption. “Volcanoes are formed when there is great stress inside the earth’s crust and the pressure of magma reaches so high that it finds its way upward causing an eruption.

There are several categories of these natural forces to which we have come to know as determinism. No man can ever predict when these natural forces are going to occur but can certainly tell when they have came and left.

Air condenses on their slopes and around their peaks forming rain and snow that can trigger devastating floods and avalanches.

Tectonic plates are able to move because the Earth's lithosphere has a higher strength and lower density than the underlying asthenosphere. Lateral density variations in the mantle result in convection. Their movement is thought to be driven by a combination of the motion of seafloor away from the spreading ridge (due to variations in topography and density of the crust that result in differences in gravitational forces) and drag, downward suction, at the subduction zone
