Earthquake dangers and community preparedness Essay

Earthquake dangers and community preparedness - Essay ExampleAdapted from Geography seisms, by BBC, 2012, Retrieved 26 November 2012 from http//www.bbc.co.uk/schools/gcsebitesize/geography/natural_hazards/seisms_rev1.shtml. Copyright 2012 by Author. Reprinted with permission. A discharge in these plates results in vibrations in the crust of the earth, a phenomenon referred to as earthquake. Patel and Revi (2010) define earthquake as a sudden movement of the crust of the earth repayable to volcanic activity or release of stress accumulated along faults. The logarithmic Richter scale measures the magnitude of earthquakes. The greatest magnitude measured to date has been 9.5 for an earthquake that rocked Chile, causing tsunamis and killing about 1,655 people injuring 3,000 others (US Department of the Interior, 2012). Dangers of earthquake to man and the environment Indeed, these shifts of the earths crust referred to as earthquakes impact on ecosystems and habitats. The unify Natio ns Environmental Program (2004) gives an example of the 1976 Sichuan earthquake that led to the loss of the habitat for the giant bear panda. The tsunamis that result from earthquakes could kill fish and other sea behavior with consequent disturbance of their habitat. For example, the 1964 Alskan earthquake uplifted the floor of the sea by 33 feet leading to destruction of calcareous marine organisms. Earthquakes destroy plant life. It is feared that in Northern California, a place of convergence of three tectonic plates, the occurrence of an earthquake would cause a massive loss of Redwood trees (Patel & Revi, 2010). As humans seek to construct temporary shelters, reconstruct and meet their energy needs, they could cause deforestation thus ecosystem depletion (BBC, 2012). Similarly, other risks such as quarrying for reconstruction could advertise negatively impact on the ecosystem. Wildlife also gets affected either directly or indirectly because of earthquakes. Some of these env ironmental effects of earthquakes affect human health. The beetle off disposal and debris resulting from an earthquake could negatively impact the environment and human health. The affected would have to look for appropriate ways of disposing off such hook so as to rebuild their structures. The aftermath of the 2008 Sichuan China earthquake saw agricultural fields turned into dumps with building materials (BBC, 2012). Water sources also got soil with the dumps. Therefore, it would be critical to ape Los Angeles County Sanitation Districts which after the 194 earthquake disposed off the rubbles appropriately (Patel & Revi, 2010). This would be important in seeking to lower contaminant of the environment and disease to humans. Other than diseases, earthquakes could cause fires which burn down the assets of people, setting them back economically. In addition, the short term looting in the event of an earthquake would have similar devastative effects. Landslides could bury families under rubbles, with some bodies not being retrieved even after the disaster. The cost of rebuilding also adds to peoples fiscal burdens. Preparedness towards earthquake dangers The Seattle Office of Management (2012) suggests various ways to prepare one for an earthquake as an individual. The organization proposes anchoring of appliances and tall furniture that could fall. Homes should have indispensableness supplies known to every family member. The members should also have the necessary numbers handy to be used in case of separation
