Hi, need to submit a 1250 words paper on the topic The 2011 Earthquake in Japan. In March 11, 2011, a destructive earthquake measuring 9.0 on the Richter scale struck Japan. The epicenter of the quake was near the East coast of Honshu, which was at a depth of 24.4 kilometers. According to Aislinn (2011), the movement along the two main plate boundaries caused the earthquake. Honshu Island is situated at the junction of three continental plates, the Pacific, the Philippine, and Eurasian Sea plates. Earthquakes are generated by the tectonic plates that build up the surface of the earth through bending, snagging, or breaking of these plates as they move past one another. Alexandra notes that thrust faulting caused the March 2011 earthquake. in thrust faulting, rocks positioned in the lower layer of the earth’s crust get pushed above the overlying layers. These faults occurred on or near the interface plate boundary between the North America and Pacific plates (Alexandra, 2011).
This occurred near or along the boundary where the Pacific Plate moves under Japan. The rate of convergence in the Pacific Plate’s border near Japan is much higher than in other zones. The Pacific plate thrusts beneath Japan at the Japan Trench, and plunges to the west underneath Eurasia. these plates are rocky and they creep past each other at a slow rate. The Pacific plate moves at a velocity of 3.2 inches per year westwards towards the North America plate. As the two plates shift past one another, they release seismic pressure and energy which causes earthquakes (Aislinn, 2011). Japan is situated in a place known as the Ring of Fire. this place experiences most active volcanoes. The Pacific Basin, which holds Japan, has oceanic trenches and experiences volcanoes around it. These volcanoes and oceanic trenches contribute to the occurrence of earthquakes in Japan.
Alexandra (2011) notes that earthquakes occur under the seafloor unleash tsunamis. these tsunamis are more devastating than the earthquake itself. The violent movement of the earth’s crust displaces enormous .quantities of water. these waves are known as tsunamis. Massive fires, generated by the earthquake, were blazing out of control leading to death, injuries, and the destruction of property.
