different Earthquake Cases Introduction: In this essay I will be comparing 2 different cases of Earthquakes, 1 in an MEDC (More Economically Developed Country) and the other in an LEDC (Less Economically Developed Country) both of a magnitude of 7.0. The two earthquakes that I will be comparing are the Kobe Earthquake in Japan in 1995 of a magnitude of 7 (for the MEDC) and the Haiti Earthquake in 2010 of a magnitude of 7.0 (for the LEDC).I will be comparing the impact after the Earthquake, the damage

Crail What’s a earthquake? According to the Geology Labs on-line website an earthquake is the sudden release of stored energy, caused by the shifting of tectonic plates. The energy release is a shock wave or seismic wave. The seismic wave is what causes the ground to move or shake, when this occurs we have a earthquake. According to the 2008 United States National Seismic Hazard Maps a lot of the west coast as far south as Hawaii, and north to Alaska has a lot of earthquake activity. The Pacific

Earthquakes Michael R. Rice PSHC 210 11/17/12 Unpreventable and potentially devastating, earthquakes offer geologists insight into the Earth's structure. Even though scientists cannot stop an earthquake from happening they are developing a better understanding of how and why earthquakes occur. Studying where, how, and why the earth shakes can give people more knowledge into preparing for and recovering from earthquake disasters. Although scientists cannot predict short-term forecasting

What patterns to you see in the distribution of earthquakes across the continental United States? Most earthquakes occur in the United States along the coast of the Pacific, particularly the shoreline of California, Alaska and Japan in addition to earthquakes that occur in the mid-west and east coast states and along the border amid Kentucky, Missouri, Arkansas and Tennessee. As noted, the highest levels of risk are in the west coast whereas the eastern central region is more moderate risk and

CHAPTER 2 Review of Related Literature 2.1 Foreign Literatures 2.1.1 The Simplified Method The Simplified Method is the most common procedure for evaluating the liquefaction potential of soil. Developed by H.B. Seed and I.M. Idriss in 1971, this method uses two fundamental terms: (1) Cyclic Stress Ratio (CSR), and (2) Cyclic Resistance Ratio (CSR). The CRR characterizes the liquefaction resistance of granular soils and is typically acquired from in situ tests. It can also be estimated by

GLG/200 Allen Fronabarger PLATE TECTONICS AND EARTHQUAKE HAZARDS IN LOS ANGELES There are many serious hazards associated with earthquakes in the Los Angeles metropolitan area. This includes ground shaking, ground displacement, liquefaction, fires, and tsunamis (Girty, 2009, Chapter 7). During an earthquake there are varying degrees of vibration of the ground, dependent on the magnitude of the earthquake. This violent movement of the soil can compromise the structure of buildings or other structures

The earthquake and the tsunami on the Indian Ocean (2004) On 26th of December 2004, the most horrible nightmare came true for the people living in the countries located on the Indian Ocean; Indonesia, Malaysia, Thailand, India, Sri Lanka and the Maldives. It’s one of those episodes that still are remembered today and are in the back of people’s minds. It was series of underground-earthquakes that were triggered, and the first and the most powerful earthquake at magnitude 9,3 on the Richter’s scale

surface. It is here that we will find the tectonic plates of the Earth and cause for Earthquakes. An earthquake occurs as the two blocks of the earth suddenly slip past one another (usgs.gov). Generally a quake will occur without warning, although many times there may be a foreshock (smaller earthquake near epicenter, similar to an aftershock), which is usually mistaken for the Earthquake until the actual higher magnitude quake occurs. These shifts seem to happen without warning, however, upon observation

that the event travels, and magnitude is the scale of energy released during an event. What these two things have in common is magnitude usually determines the frequency that the force will travel. We study this relationship closely so we have a good idea on what can potentially happen in the future. When there is a place that has many low magnitude earthquakes the frequency is typically low. On the contrary when there is a single earthquake with a larger magnitude the frequency can be very high
