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.

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.
