The short answer is that earthquakes are caused by faulting‚ a sudden lateral or vertical movement of rock along a rupture (break) surface. Here’s the longer answer: The surface of the Earth is in continuous slow motion. This is plate tectonics--the motion of immense rigid plates at the surface of the Earth in response to flow of rock within the Earth. The plates cover the entire surface of the globe. Since they are all moving they rub against each other in some places (like the San Andreas

waves that radiate from where the earthquake starts‚ a place called the focus. These Seismic waves are what cause the intense shaking at the Earth’s surface that can cause buildings and roads to collapse. All across the world governments are going to great lengths to ensure the safety of their citizens by building resistant structures that are designed to withstand earthquakes and prevent the immense damage their shock waves do. Body: To build are earthquake proof structure that is able to withstand

Essay on Earthquake The usual phenomena recorded in well-known earthquakes are first a trembling‚ next one or more serve shocks‚ and then a trembling which gradually dies away. In most cases‚ each shock lasts only a few seconds‚ but the trembling that follow may continue for days. Weeks or even months. Noises of various kinds usually accompany an earthquake. They have been likened to the growling of storm‚ the growling of thunder‚ the clanking and are not accompanied by these noises. At

Hurricanes and earthquakes are two of the most dangerous natural disasters in the United States. They can be very disastrous and deadly. In the United States‚ there have been 73 hurricanes since 1954. Earthquakes are harder to detect because they have to have at least a magnitude of 5 ("Earthquakes per year‚" 2009). The amount of earthquakes detected in the United States was 1656 in the past 10 years ("Earthquakes per year‚" 2009). The World Meteorological Organization is the organization that can

The January 12‚ 2010 Haiti Earthquake caused an enormous destruction in the Caribbean nation. Hospitals and government buildings collapsed along with an unbelievable amount of homes. Tens of thousands of people were killed‚ and many more were wounded. The disaster added more misery to people already struggling to get by with everyday life. Haiti is one of the poorest nations in the world. The January 12 quake demolished almost every major building in Port-au-Prince‚ Haiti’s capital. About 5‚000 schools

Although nature gives many things to mankind‚ sometimes it show its terrible side. It is obvious that most of disasters are very dangerous to anything in the world. Earthquakes are one of the terrible outcomes of nature‚ and they bring a lot of big problems to humans and the animals. An earthquake is an sudden and violent shaking

Haiti is the most impoverished country in the Western Hemisphere‚ and amongst the poorest in the world. With that being said‚ when an earthquake happened just kilometres away from Haiti’s capital of Port-au-Prince‚ the country was hardly prepared (Fierro & Perry‚ n.d.). Haiti has overcome various natural disasters‚ including hurricanes‚ tsunamis‚ floods‚ landslides‚ and other tropical storms. Haitians expect these natural hazards to occur‚ due to past events and the location of the country making

K. E. Geology 100 4/15/13 Japan earthquake On March 11‚ 2011‚ Japan was hit by a magnitude 9.0 quake at about 2:50 pm. This would turn out to be the largest earthquake in the past thousands years to ever be recorded. What caused this massive destruction one might ask? This devastating quake was caused because Japan is located between two major tectonic plates. When a large number of plate movements occur‚ the Pacific Plate makes its way below a subduction zone. When plate movements

the ocean waves. Though this motion seems calm and harmless‚ it is‚ in reality‚ a great force of nature. The force becomes even stronger when it is mixed with one of nature’s greatest disasters: earthquakes. When these two great forces collide‚ structure and society are greatly impacted. Though an earthquake can happen at almost anywhere and anytime in the world‚ they all start out in the same way. Deep beneath the Earth’s surface‚ in the mantle‚ rocks are always in motion‚ rising and sinking in convection
