Assignment: Earthquakes Sci/245 Assignment: Earthquakes Plate margins are involved in the Earth as a major provider to many of Earth’s geological formations. These plates are approximately 100 kilometers thick, which is very thin compared to the largeness of a 6000-kilometer radius of the Earth. Most major plates include both continental crust and oceanic crust. An earthquake is the shaking of the Earth’s crust due to a sudden release of energy. They are caused by stress that builds

The New Madrid earthquakes of 1811–12, were three large earthquakes that happened near New Madrid, Missouri, from December 1811 to February 1812. There were thousands of aftershocks, about 1,874 of them were so large that they could be felt 190 miles away as far as Louisville, Kentucky. It is unknown how many lives were lost during the quakes. Scholars say that the number most likely wasn’t very large. The area that was affected by the quakes had a small population. The main one of the shocks produced

Natural Disaster (Earthquake) Nature provides a lot of good things to mankind. Without nature, this world is simply means nothing. However, there is also a creepy side of nature which will cause frightful effects. Earthquake is one of the examples that will cause losses of life, shortage of foods and waters, and property such as houses, buildings or farms will be destroyed. Earthquakes can define as naturally trigger quaking of the earth and its crust caused by the steam swells

Some scientists discovered the historical and scientific evidence for a megathrust earthquake that generated a tsunami along the Cascadian subduction zone in 1700. A few geologists used radiocarbon dating and found that at least 900 kilometers (560 miles) along the fault ruptured between 1960 and 1720 (National Geographic Society [NGS], 1996). In 1996, Japanese researchers showed North American colleagues a tsunami that struck Honshu Island in 1700 to geological reports at the Cascadia subduction

“Discuss the view that the impact of earthquake hazards depends primarily on human factors (40)”. I agree to some extent about the statement above and that human factors can affect the impact of an earthquake hazard. A hazard is an object or process that has the potential to cause harm. Ground shaking, ground displacement and flooding are some of the hazards that are produced during an earthquake. In relation to the question above the type and severity of the impact can be affected by physical

such a small scale that only geoscientists would be able to detect it. Furthermore, it was discovered that the size and number of felt earthquakes caused by fracking is low compared to other manmade triggers such as mining, geothermal activity or reservoir water storage. But

and near a major earthquake fault I have pondered and wondered why our plants shake and why our planet only shakes in specific elements of the United States. While exploring for the details to finish my report, I was also able to find out the solutions to my own individual queries. This report will reply these inquiries: How does our planet shift and when, what actives cause the Earth to shake, how are earthquakes calculated and what are the two kinds of body waves and earthquake generates.

distribution of earthquakes across the continental United States? The west coast of the US consists of the highest levels of risk by a wide margin, particularly in the south-west (on the pacific tectonic plate fault line). Central Eastern regions bear areas of moderate risk. Northern and South/south-easterly regions bear no significant risk. 2) Locate your home on this map and make a note of the relative risk to you by indicating the color where you live. The USGS also reports on earthquakes around the
