FRANK KAMARA 11/29/11 EARTHQUAKES Earthquake is one of the worst natural disasters of all, it destroys, kills, and even left some people unfound for days or weeks “it was estimated that hundreds were missing after the first earthquake” ( Some earthquakes are accompanied by seismic sea waves that cause excessive damages and be noticeable in shorelines. Earthquakes sometimes cause tsunamis, which may lead to loss of life and destruction of properties. This paper discussed how earthquakes happen, how are they measured and predicted, and the damages and health repercussions an earthquake can cause. It also discussed about the preparations and preventions of an earthquake. An earthquake is caused by tectonic plates getting stuck and putting a strain on the ground. The damage becomes so great that the rocks give way by breaking and sliding along fault planes. “The strain becomes so immense to facilitate the rocks by flouting and descending along blunder planes’ ( Earthquakes may occur naturally or as a result of human activities. Some smaller earthquakes are cause by natural and artificial disasters. “Smaller earthquakes may also be caused by volcanic activity, landslides, mine blasts, and nuclear experiments” ( The word earthquake is use to describe any seismic event, whether a natural phenomenon or an event caused by humans that generates seismic wave. Most earthquakes are related to tectonic nature of the earth. Earthquakes are measured with a seismometer commonly known as a seismograph. The magnitude of most earthquakes is measure on the Richter scale, invented by Charles F. Richter in 1934 9. The Richter magnitude is calculated from the amplitude of the largest seismic wave recorded from an earthquake. “A magnitude of three or lower means that the earthquake is being hard to notice, and a
