Natural Disaster: - Natural Epidemic, Flood, Earthquake, Landslides, Drought, Cyclones, etc. Some great disasters that come all of a sudden creating havoc on humanity. Disasters that fall as an adverse situation harming life and material on a large scale. As a part of this movement, sometimes, they collide against each other. And, after the collision, they might still continue to push each other. As they continually keep pushing each other, there is a pressure building up – across these plates below the surface. And, then, at a certain time, one of the plates might slide over another. This causes an earthquake.Some earthquakes might be caused by activity above the surface.

Earthquake

Earthquakes refer to shaking of earth. There is continuous activity going on below the surface of the earth. There are several large plates (size of continents) below the surface of the earth, which move (at a very slow speed). As a part of this movement, sometimes, they collide against each other. And, after the collision, they might still continue to push each other. As they continually keep pushing each other, there is a pressure building up – across these plates below the surface. And, then, at a certain time, one of the plates might slide over another. This causes an earthquake.Some earthquakes might be caused by activity above the surface. For example in a mountainous region, there might be a heavy landslide. Due to a huge mass of land falling, at the point of the fall, there could be a minor shaking of earth, due the impact of fall. However, usually, such earthquakes are not very major....

Floods/Tsunami

Floods Floods refer to huge amount of water reaching land in a short span of time, causing land surface to be submerged under water – at places, where, land surface is usually not covered with water. Floods could be caused due to natural causes, or, human activities, or, a combination of both. Floods are caused by discharge of huge volume of water in a short span of time, at a rate, such that the water cannot be carried away from the scene of discharge. Some of the possible reasons for such huge discharge of water could be: very heavy rainfall (say: due to cyclones, typhoons etc.) in a short span of time. It should be noted that the amount of rainfall itself is not a sufficient cause, the duration within which the rainfall is received is equally important contributorbreach in levy, dams etcvery high tidal waves (sometimes in the aftermath of a seismic activity, e.g. earthquakes) etc. – also called Tsunamis Usually, flooding impacts a large area, wherein entire district or states might be flooded. However, sometimes, flooding is very local, i.e. limited to just one city, or, parts of it. Most often, the localized flooding is caused due to human activities, rather than natural phenomenon. A natural phenomenon might seem like the immediate trigger, but, in reality, this is caused by human activity....

Cyclone

Cyclones, Tornadoes or Typhoons   These are high-speed winds occasionally accompanied by heavy rainfall. These winds cause structural damage, snapped overhead wires and possibility of floods. Because of damage to structure and overhead wires, many services could be disrupted. Heavy rainfall could also cause flooding. Many times, these could last for a few days. In such cases, any restoration and relief activities cannot even start until the disaster starts subsiding. Due to the development in meteorological sciences, such natural disasters can be predicted to a reasonable degree. And, in most cases, it is possible to get a warning of up to several days. Usually, it is possible to take at least some preventive measures - during these few days of warning. In most cases, the preventive measures would include: �  Moving into places which are safer, e.g. buildings which are structurally sound and, are not prone to flooding. �  Not venturing out to sea etc for sports, fishing etc. However, in spite of these warnings, damage to property cannot be mitigated much, as, immovable structures cannot be relocated. People inhabiting such geographical areas which are prone to such disasters could take some fundamental care while building homes or other structures. These are: �  Sturdy home, with very strong foundation and structure. �  Typically, most...
