Unpreventable and potentially devastating, seisms decl be mavenself geologists insight into the Earths structure. Even though scientists can non stop an earthquake from happening they argon developing a better understanding of how and wherefore earthquakes occur. Studying where, how, and why the earth shakes can give mass more knowledge into preparing for and recovering from earthquake disasters. Although scientists cannot predict short-term forecasting with any true accuracy, they can determine which areas are at risk of experiencing a substantial earthquake done long-term forecasting (Murck, Skinner, & Mackenzie, 2008).
Earthquakes are a result of ii tectonic plates moving past one another. Because the plates do not slide past each other smoothly practically the edges of the plates, or plate boundaries, stick together whereas the rest of the freeze continues to move (Wald, 2009). The plate boundaries are comprised of numerous faults, and it is along the faults where the mass of earthquakes occur (Murck, Skinner, & Mackenzie, 2008).



The nix that normally forces the plates to the move past one another begins to store until the power of the parts of the plates still in front overcome the friction caused by the parts that are stuck and release the plate (Wald, 2009). The result is a release of the stored energy that then radiates as seismal waves in all directions (Murck, Skinner, & Mackenzie, 2008). The meter of pent up energy determines the size of the earthquake and the resulting seismic waves. When the seismic waves reach the Earths surface the ground shakes as the Earth continues to move through the wave (Wald, 2009). The destruction caused by an earthquake is the consequence of the sustained shaking of the ground (Murck, Skinner, & Mackenzie, 2008, p. 119). Ground motion is the primary hazard in earthquakes with landslides, tsunamis, ground liquefaction, and fires as secondary hazards...If you want to get a full essay, order it on our website: Orderessay
