¶ … Tsunamis and Earthquakes in Japan
This article looks at the Geographical effects of the tsunami and earthquake. It is a research that analysis the disastrous implications of tsunamis and earthquakes to the human and physical environment of the Japanese people. It considers a geographical analysis as a type of analysis that stipulates the area covered by a study. The paper outlines the causes of tsunamis and earth quakes, areas where it were affected in Northern Japan, the aftermath effect of the tsunami and earth quakes in Northern Japan finally a conclusion of what is expected of the entire world in relation to the calamities in Northern Japan.
A tsunami is a consequential oceanic shake stimulated up by tectonic, conventional processes or volcanic action on ocean floors. An earthquake is a vibration at the epicenter of the earth resultant from subversive movements along fault planes or from volcanic activity or from another disruptive activity. Both tsunamis and earthquakes are environmental phenomena that are known to have both man-made and physical implications.
Causes of Tsunamis and Earthquakes
These phenomena have been attributed to several causes; human and physical. The making and testing of nuclear weapons in deep sea or oceanic waters is considered to be one of the causes of earthquake and tsunamis. The concept behind is when the floor of the sea deforms and, as a result, displaces the overlying water, for example, the tectonic earthquake occur with this formation and can create a tsunami if it occurs in a large water body. Other major causes are volcanic eruptions, deep mining activities and isostatic adjustments between the moon and earth. Earthquakes are engendered by the stretching and compression of land. The two phenomena are related in a way that one...
In the year 1993, Hokkaido earthquake generated a tsunami.
Geographical effects of tsunamis
Tsunamis affect the geographical structure and potential of a locale. The impacts mostly affect physical environments; soil and water. These two are which are essential entities in Agriculture hence limit production. Tsunamis cause salinity of soil. The soils in the coastal areas turn out to be saline due to secondary salinization process. The saline water contains excess soluble salts like chlorides as well as sulphates of sodium, carbon and magnesium. These are the end-products of volcanic activity. The resultant effect of this in agriculture is that weak plants that grow in saline environment are associated with soaring osmotic stress thus causing poisonous ionic effect, less water in soils and nutritional imbalance resulting from interaction of complex nutrients (Petersen et al., 2012, pg 187). It also exerts a harmful effect on soil-biot.
In terms of geographical locale, Tohoku was immensely affected. Some of the major effects include: over a million houses were in a black out as electricity was cut short. The city experienced major damages relating to fire at Chiba refinery, demography trend, and devastation of other geographical sectors amounting to the town's economic status.
Tsunamis have affected a very large geographical coverage in the Northeast coast of Japan. Earthquake magnitude of 8.8 cased a massive damage in Sendai. This was the strongest tsunami and earthquake to be ever registered in the accounts of earthquake and tsunami disasters in Japan. It led to the rise in number of deaths to over 1,000 people. An estimated number of 200 to 300 dead bodies were sported alongside waterlines in the city of Sendai. Many homes were destroyed leaving…
