Every year, millions of people around the world lose their lives and property in the earthquakes. Considering the gravity of the problem, there is dire need to make the structures resistant against earthquakes as well as to have an effective disaster management system in place to counter the effects of earthquakes. Contents of the paper This paper does a detailed analysis of the research topic i.e. earthquake and explores its various aspects. The aspects discussed in the paper include but are not limited to discussion of the engineering problem, its importance, its relation with geology and engineering, impacts of the engineering problem on the society, challenges associated with it, geological analysis of the problem, and strategies that may be employed to deal with this engineering problem. In addition to that, a case study is discussed in detail. The case study is about a real life earthquake incident that occurred within the last ten years, and that had huge implications on the society. The paper discusses ways in which effects of the earthquake were dealt with, and the potential strategies to avoid the effects of such incidents in the future. Relation between earthquakes and geology Earthquakes are fundamentally related to geology because they happen as a result of movement of the tectonic plates. There are four layers of earth, that include the inner core, the outer core, the mantle and the crust when arranged in an inside out fashion. Although the crust and the mantle constitute a thin layer on the earth’s surface, that is fragmented into different pieces that may slide past each other. An earthquake occurs when two blocks of earth slip across each other. The surface across which the slip happens is known as the fault plane. Earthquake starts at the hypocenter that is directly below the surface of earth where earthquake happens, known as the epicenter. Relation between earthquakes and engineering Earthquakes are related to engineering because their occurrence imparts the need to engineer the structures in such a way that they can resist the effects of earthquakes. Every structure has a different foundation design that is engineered in such a way that it can effectively transfer the load of the structure to the earth and can help the building withstand all external shocks and risk factors including heavy winds and earthquakes. Foundation designs of buildings if modified appropriately, make the buildings earthquake-resistant. Impacts of earthquake on the society There are numerous impacts of earthquake on the society that include but are not limited to disrupted normal life, loss of life, loss of property, loss of housing, breakdown of the social order, damaged infrastructure, loss of business, disrupted communication channels, loss of the industrial output, and disrupted marketing systems. “The effects of an earthquake can also cause dangerous landslides, fires, gas line and electric explosions, and floodwaters from collapsing dams” (Pollard). Earthquakes have numerous short term and long term effects. Many children get kidnapped during the earthquakes. Long term effects of earthquakes include decline in the socioeconomic system of the country. “Evidence points to elevated rates of posttraumatic stress disorder (PTSD), depression, and earthquake-related fears in children ...Download file to see next pagesRead More

Haiti earthquake

...?Yvener Lisca Mr.Marlowe Earth science 11/11 Haiti Earthquake The Earthquake An earthquake is a tremor that happens as result of sudden energy release that creates seismic waves in the earth’s crust. They occur anywhere in the world as long as there is enough elastic strain energy stored to drive fracture along fault planes. Once the faults have locked on to each other, there is an increase in stress and likewise the strain energy stored in the surfaces of the faults. The energy will be released as combination of strain seismic waves that are radiated, cracking of the rocks and frictional heating of the fault surface (Miriam 133). This causes earthquake. Three types of...

...Running head: Alaska earthquake GOOD FRIDAY EARTHQUAKE (27th March 1964) Alaska's seismic and tsunamigenic history is quiet old. Alaska is very seismic with the plates that lie under the North American Plates. This whole zone is known as Aleutian-Alaska. This zone is a threat to the coastal areas with view to tsunami. There are massive displacements and movements in the plates which lie under this zone. Three past displacements have resulted into destruction in Alaska and area surrounding this area. 27th March 1964 is remembered as the worst day in the history of Alaska. It was 5.36pm Alaskan time, people were traveling home and others were preparing for the Good Friday services. Near Prince William's...

Earthquake Impacts

...Earthquake Impacts An earthquake is literally defined as "a sudden and sometimes catastrophic movement of a part of the Earth's surface Wikipedia", 2006). Caused as a result from the dynamic release of elastic strain energy that radiates seismic waves, earthquakes typically result from the movement of faults, planar zones of deformation within the Earth's upper crust. Earthquakes most often occur in places where the stress level which results from the differential motions of these plates is stronger than the strength of the crust in that same area. The areas in which the tectonic plates are found are also the areas with the greatest stress level, which explains why these...

...Economical Impacts of Earthquakes on Society Why is earthquake interesting to me? Long time ago, I went to Saudi Arabia with my friend to visit his chums. It was a pleasant day until the time we heard the news that there was an earthquake nearby, but this news did not quite gather our attention, because Saudi Arabia is not a place where earthquakes happened quite often. We completed our trip by visiting our friends. And then we heard about the start of the earthquake near the city we lived in. I heard some people talking about lots of casualties which took place due to the earthquake, but I couldn’t imagine what the losses were in...

...Earthquake: Japan, Chile, and Haiti In terms of Richter magnitude size, Japan’s earthquake registered at a moment magnitude of 9.0 on the Richter scale (USGS, 2011). The Haiti earthquake on the other hand registered at an intensity of 7.0 (Disasters Emergency Committee, n.d), and the Chilean earthquake registered at a magnitude of 8.8 (Reuters, 2010). In Japan, the thrusting of the Pacific plate under the North American plate caused the earthquake; Japan is located on top of the North American plate (New York Times, 2011). In Chile, the earthquake was caused by the movement of the Nazca and South American tectonic plates. The earthquake was marked by a thrust-faulting focal mechanism which saw the subduction of the Nazca plate... ...
