The phenomena of Natural Disasters An earthquake is sudden motion or trembling of the ground produced by the abrupt displacement of rock masses. HOW DO THEY OCCUR? The earth’s outer shell is divided into seven major and some smaller plates which are constantly in a dynamic state‚ pushing against‚ pulling away from‚ or grinding past one another. Forces build up as the plates attempt to move in relation to each other. When the adhesions along the fault give way‚ stored energy is released in the

rainfall‚ which can cause rivers to overflow and devastate a whole community. Another culprit to flooding is hard dry soil. When the soil has not been replenished in a long period of time‚ it cannot absorb the downpour rapidly enough. Building on flood plains is also a growing concern. Floodplains are flat areas of land with higher elevation on both sides. After it rains it is a place where unwelcomed floodwaters are kept. If there is construction in floodplains it will only be destroyed by incoming

there are many ways science is involved in floods. Looking up the difference in scientific news and daily news I have found that scientific news talks more directly to how natural disasters effect the world. Going through the steps in the scientific method‚ from the Colorado flooding article‚ I have asked myself the question is climate change to blame? Two degrees of warming worldwide seems abstract‚ but bridge-collapsing‚ home-destroying‚ killer floods are the sorts of weather events that can bring

Engineering Disaster Civil Engineers build significant structures that can last more than a century‚ some of these structures such as Burj Khalifa‚ pyramids and evil towers in France can be considered as landmarks‚ because of its history and its beauty of design. Civil Engineers study the four factors of building structures to determine which tools and materials they will use in order to build permanent structures. Although engineers studying the factors and take the determination‚ there is some
