The Most Deadly Natural HazardEarthquakes-being among the most deadly natural hazards-strike without any prior warning, leaving catastrophe in their wake with terrible loss of human lives as well as economic loss.Technically, an earthquake (also known as tremor, quake or temblor) is a kind of vibration through earth’s crust. This vibration occurs as a result of powerful movement of rocks in the earth’s crust. These power full movement trigger a rapid release of energy that creates seismic waves that travel through the earth Earthquakes are usually brief, but may repeat over long period of time. (Earth Science. 2001)Earthquakes are classified al large and small. Large Earthquakes usually begin with slight tremors but rapidly take form of violent shocks. The vibrations from a large slight tremors and do not cause much damage. Large Earthquakes known to take down buildings and cause death and injury (Richter, 1935). According to same statistics, there may be an average of 500,000 Earthquakes every year but only about 100,000 can be left and about 100 or so can cause damage each year.The study of Earthquakes is called seismology. Seismology, studies the frequency, type and size of Earthquakes. Earthquakes are measured using observation by seismometers. The magnitude of an earthquakes and its intensity is recorded on a numerical scale known as Richter scale. On this scale, 3 or less is hardly noticeable. Earthquakes with magnitude of more than 6.5 can cause heavy damage (Earth Science. 2001).The effect of an earthquakes are strongest in the area which is near its epicenter. The extent of the earthquake vibration and further damage of the region is partly dependent on the features of the ground. The worst possible damage occurs in the densely populated areas where structures, are not built to withstand intense shaking. Damage and loss of life incurred during earthquakes is due to falling buildings and flying glass and objects. In certain areas, an earthquakes can cause mudslides that can bury areas under it. Powerful submarine earthquakes cause tsunami or a chain of fast moving waves in the ocean that ripple outward from earthquakes epicenter towards coastal areas causing surmountable damage (http\:www.USGS.Org). on
