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

examples of earthquakes‚ assess the extent to which attempts at prediction and mitigation may have influenced the impact of the hazard. An earthquake is the result of a sudden release of energy in the Earth’s crust that creates seismic waves. Earthquake is a major threat to the human and natural environments‚ in which people died‚ buildings collapsed and cities destroyed. Prediction and mitigation are usually conducted in order to reduce the impact of an earthquake on environment. Earthquake prediction

San Francisco have all experienced a fault shift. In the case of Houston‚ the likelihood of an earthquake is extremely low. The instances of a fault shift on that area of the North American Plate don’t occur often. Earthquakes that occur are not by normal means of plates shifting but from the process of fluid extraction (Fehling 19). Seattle on the other hand has a very high probability of an earthquake occurring. There are three different types of quakes that the city experiences crustal quakes‚

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

Prediction Why didn’t scientists know about the faults that caused the two earthquakes? Prior to September 4th‚ there were no surface signs of the Greendale Fault or the fault that generated the Lyttelton aftershock and there was no evidence for seismicity on these faults (i.e. ‘foreshocks’). Seismic surveys have located some ‘hidden’ faults across parts of the Canterbury Plains‚ but these particular regions had not been surveyed for this purpose. An oil-gas seismic survey had been carried out

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
