THE NEW MADRID EARTHQUAKE OF 1812 Some of the most severe earthquakes in the United States occurred not on the Pacific Coast but in the middle of the continent in southeastern Missouri near the town of New Madrid. There are many things that were unusual about the New Madrid earthquakes of 1811-1812. The location is a surprise‚ the damage was catastrophic but we did learn from it. Just after 2 o’clock AM of December 16‚ 1811‚ the Mississippi River valley was hit by an earthquake so strong

Martin Luther Martin Luther King Jr. was born on January 15‚ 1929 in Atlanta‚ Georgia. King‚ both a Baptist minister and civil-rights activist‚ had a seismic impact on race relations in the United States‚ beginning in the mid-1950s. Among many efforts‚ King headed the SCLC. Through his activism‚ he played a pivotal role in ending the legal segregation of African-American citizens in the South and other areas of the nation‚ as well as the creation of the Civil Rights Act of 1964 and the Voting

1. Do some Internet research on Chevron’s use of seismic imaging technology. Briefly explain how it works and how it has helped Chevron discover new oil and gas reservoirs. Answer: To understand how seismic imaging technology helped Chevron discover new oil and gas reservoirs‚ we must investigate the mechanism of seismic imaging technology. This technology sends the shockwaves to underground to know if there is crude oil and other natural gases beneath the ground. In this way geologists calculates

LOCATION THEME: Missouri 4.0 earthquake felt across 13 states NewsCore - February 21/ 2012 A 4.0 magnitude earthquake struck Tuesday in Missouri and was felt across 13 states. The epicenter was located 5 km underground‚ about 240 km south of St. Louis‚ near the New Madrid fault line. There was no significant damage reported from any of the surrounding states the felt the tremor. Scientist say this is a reminder that though earthquakes are rare in the Midwest United States‚ they still have

“Discuss the Extent to which volcanic and seismic activity are evidence for plate tectonic theory” (40) Plate tectonics is the theory that explains the structure and motion of the Earth’s lithosphere. The theory states that the Earth’s crust is split into large sections called tectonic plates‚ and these move relative to one another creating boundaries at which plates converge‚ diverge and move past each other. Alfred Wegener pioneered the theory of continental drift in the early 1900s which he supported

talked about how icebergs may behave the same as moving continents‚ and how therefore plate tectonics caused the movement of continental crust. Holmes on the other hand had a theory that heat was trapped in the Earths convection currents‚ he used seismic profiling which is throwing explosives in to the sea and seeing how they would react to see the shape of the sea bed‚ as this would show the shape of the oceanic plates‚ however Holmes was wrong with his theory as he did not understand that the solids

“The hazards presented by volcanic and seismic events have the greatest impact on the world’s poorest people.” To what extent do you agree with this view? (40 marks) Volcanic and seismic events can take place all over the world and therefore both more economically developed countries (MEDCs) and less economically developed countries (LEDCs) can be affected. In the last 30 years there have been multiple examples of where volcanic and seismic events have had an impact on both MEDCs and LEDCs. Some

‘Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events’ In 1912‚ Alfred Wegener published his theory that a single super continent named Pangaea once existed about 300 million years ago. He proposed that Pangaea then later split into two continents of Laurasia in the north and Gondwanaland in the south and that today’s continents were the result of further splitting of these two land masses. Where the plates split are known as plate boundaries

that these currents do take place. We know that the mantle is liquid and has high temperatures as magma that originates in the mantle is molten. This means that convection currents can occur. This part of plate tectonic theory is supported by global seismic activity because if convection current did not exist and plates were not able to move‚ earthquakes would not occur at any plate boundaries‚ but particularly at collision plate boundaries as there would be no plate movement. Another part of tectonic

helps our understanding of the distribution of seismic and volcanic events(40) The global seismic and volcanic activity is concentrated along the margins of the earth’s plates‚ which are broken pieces of the crust and are moved by convection currents that are caused by heat rising and falling inside the mantle generated by radioactive decay in the core. This movement of the plates and the Earth’s inner activity is called plate tectonics and can cause seismic and volcanic activity. However‚ earthquakes
