Essay on Earthquake

  • Earthquakes Essay

    With an earthquake, it is huge in the middle then diminishes as it moves outward from the epicenter. The events that cause the earth to quake and shake are when the tectonic plates move. The more violent the tectonic plates move or quicker they move, the larger the earthquake is. The Richter scale is used to measure earthquakes. The Richter scale measures the earthquake’s magnitude. The magnitude is calculated from the amplitude of the largest seismic wave recorded for the earthquake. The magnitudes

    The Boxing Day tsunami could not have occurred if the foci of the earthquake had not been 160km south west of the Sumatran city of Banda Aceh in the Indian Ocean. If it had been further towards the land then the tsunami waves are unlikely to have been able to reach 28m in height and thereby cause the devastation they did when encroaching 800m inland. Although sizeable damage would have been inflicted by an event of its size if located under or nearer to land, this is not possible due to the location

    These faults are the locations of earthquakes, and earthquakes come with seismic waves. The first wave to hit the surface destination is the Primary wave, a wave which moves in a curve formation and pushes outwards from the Earth core, making a building "jump". The next wave reaching the destination in an earthquake is the secondary wave, which pushes things aside as it goes away from the core, in a "snake" motion. The last wave to hit the destination point is the Surface Wave, moving in a curve

    and where volcanoes and earthquakes will occur. Large scale monitoring of tectonic activity does allow us to narrow down the locations and time frames however, and we monitor volcanoes and earthquakes in many ways. The most widely used method is studying the geographical area of the volcano. For volcanoes scientists can use seismic waves to show if a volcano is getting ready to erupt. Many volcanoes experience an increasing intensity in frequency and size of earthquakes as they prepare to erupt

    It was later discovered that there must be different types of plate boundaries according to the natural hazards that occur. For example earthquakes are distributed along the Eurasian - Australian plate boundary where there are no volcanoes. The theory of plate tectonics explains that oceanic plates, because they are denser, always subduct continental plates. Here two continental plates meet – so scientists developed a theory that fold mountains were created. The two plates merge together; neither
