Research paper - Essay Example Earthquakes are believed to be caused by different occurrences that include glacial rebounding, sliding of tectonic plates that lie over each other, and by sudden discharge of stored strain that is accumulated along a fault line. The severity of a shake from an earthquake is usually as a result of three factors i.e. its magnitude attenuation of a wave that causes the earth quake as it moves through the earthââ¬â¢s surface and the possible disruption caused by different rock structure (Hough par 9-12). These vibrations can be predicted before they happen in a place. When these vibrations happen also, they result in major disruptions to physical features. However, the major cause of investigation has resulted from the threat these vibrations cause to people. The ability to predict great causes of damaging events that are likely to face an area in future time is a basic element of risk reduction development practices. It becomes an important element when it is facing emergency and le ad to development of a good planning for such emergency (Albarello and Meletti 1-2). Earthquakes are caused by seismic waves. The intensity of these waves is measured with a machine known as a seismometer. The depth of the earthquake is another determiner of its intensity. Earthquakes are a major threat to life because if they happen with great magnitude, they lead to destruction of properties in which people live. When they happen on the water, they result to tsunamis that are likely to result in disruption of waters and seizing of ships. The commotion caused on the water also is extended to the coast, which causes major deaths of people at such coastal lands and destruction of property. Before the 1970s and 1980s, prominent scientists were optimistic that reliable prediction of earthquakes was possibly going to come. This was facilitated and motivated by the ground breaking prediction event of Soviet Union prediction of an earthquake and the successfully accomplished prediction of Chinese earthquake that happened in Haicheng. However, even with those optimistic achievements, there was a lot of pessimism because still many predictions were not reliable by then (Hough 34). Today, prediction of earthquakes is possible by scientists who agree that the understanding of ground motion attenuation relationships is an important aspect of predicting possibility of there being an earthquake. In March 2009, an Italian technician observed the radon and noticed some abnormalities and predicted that a great magnitude earthquake would be experienced. Although seismologists did not concur with that laboratory scientist, a fatal earthquake was experienced in Lââ¬â¢Aquila barely a month after the prediction. The earthquake claimed many lives and were injured while a lot of property was destroyed and many were displaced from their places. Forecasting of earthquakes is faced with many debates about their occurrence once they have happened. For example, when it happened in cit y of Lââ¬â¢Aquila a lot of questions and debates followed; scientists were fiercely faced by contradiction basing on their ability to forecast such dangers. This earthquake was so destructive such that everyone affected by it rose against the people who are responsible for predicting (Albarello and Meletti 3). Currently, there are many prediction methods for earthquakes developed such that one does not have to ask whether it is possible to
