I chose to research earthquakes and the prediction of earthquakes because I was curious as to how they work. In this paper‚ I will discus the history of earthquakes‚ the kinds and locations of earthquakes‚ earthquake effects‚ intensity scales‚ prediction‚ and my own predictions. An earthquake can be defined as vibrations produced in the earth’s crust. Tectonic plates have friction between them which builds up as it tries to push away and suddenly ruptures and then rebounds. The vibrations

powerful the earthquakes that the Anatolian fault produced. So what is the history of the fault? Where did other earthquakes happen? How many people died? Is there another earthquake on the horizon? Well I am glad you asked. The country of Turkey lies on the Anatolian Plate. The fault is a strike-slip fault much like the commonly known San Andreas Fault in the United States. The Anatolian fault is almost as active as the San Andreas‚ and is very well known for the size of the earthquakes that it produces

What are Earthquakes? The actual defining of a earthquake is: A sudden and violent shaking of the ground‚ sometimes causing great destruction‚ as a result of movements within the earth’s crust or volcanic action. Basically what its saying is that when a tectonic plate slips past another and when that happens its called a fault or fault plane‚ but when a earthquake happens it has been proven that it can deform the earths crust permanently. Something interesting is

EARTHQUAKES Introduction and Terminology • Vibrations in the earth’s crust that occur when strain in the crust is suddenly released by displacement along a fault line • Focus = point at which an earthquake originates inside the earth. May be many km below surface • Epicentre = the point on the earth’s surface directly above the focus. Strongest shock normally felt here. Most damage usually occurs here. • Seismology = the study of earthquakes – from Greek – seio – to shake

Earthquake Resistant Bridges Jacqueline Stoy 4/24/2013 Geography of Cultural Diversity 3350:275 Tuesday/Thursday 12:05-12:55 Throughout history‚ bridges have been a primary means of transportation. Unfortunately‚ natural disasters have come to destroy such bridges on many occasions. One of the most deadly natural disasters to face the bridges is earthquakes. The movement of the ground causes the supporting beams and columns to twist and collapse‚ often resulting in injury or death for

been struck by an earthquake. You are a scientist with the USGS and need to figure out all the specifics on the earthquake because an earthquake has never occurred here before. You have a few things to do as a person working for the USGS to keep your job as the seismologist on staff. 1. Using the 3 seismograms recorded‚ figure out the epicenter location using the data and the P/S wave time-travel graph. One of the seismograms has been done for you. 2. Determine if the earthquake came from a fault

1.Earthquakes 1. According to dictionary.reference.com an earthquake is a: Series of vibrations induced in the earth’s crust by the abrupt rupture and rebound of rocks in which elastic strain has been slowly accumulating. The earth is made up of tectonic plates these are massive slabs of rock floating on magma ‚as the plates move about‚ they spread apart‚ collide‚ or slide past each other‚ This is the main cause of volcanoes and earthquakes Earthquakes occur in many regions all over the world

others‚ but no matter the severity‚ there is usually a loss‚ and a cry for help. The first one I want to talk about is the earthquake that hit Haiti in 2010. By January 24th‚ at least 52 aftershocks (a smaller earthquake following the main shock of a large earthquake)‚ measuring 4.5 or greater had been recorded. An estimate of three million people were affected by the earthquake. Death toll estimates ranged from 100‚000 to 160‚000. 316 total had been affected overall. Estimated 250‚000 residences and
