Natural disasters

(Umm-e-Habiba, Karachi)

Over the centuries, scientists have been using this natural disasters to further their knowledge and to challenge nature itself by developing new equipment or new form methods to predict calamities through studies such as animal predictability of natural disasters to formulate solutions.Natural disasters in Australia Natural disasters are events that occur naturally such as earthquakes, cyclones, Storms, and floods. These kinds of disasters can cause significant physical damage, interruption of business services and personal injury/loss of life.

One common natural disaster is flooding, which occurs when a river bursts its banks and the water spills out onto the floodplain. This is far more likely to happen when there is a great deal of heavy rain, so during very wet periods, flood warnings are often put in place. There are other risk factors for flooding too: steep-sided channels cause fast surface run-off, while a lack of vegetation or woodland to both break the flow of water and drink the water means that there is little to slow the floodwater down. Drainage basins of impermeable rock also cause the water to run faster over the surface.

Earthquakes are another common natural disaster that can cause many fatalities. The movements of the plates in the earth’s crust cause them. These plates do not always move smoothly and can get stuck, causing a build-up of pressure. It is when this pressure is released that an earthquake occurs. In turn, an earthquake under the water can also cause a tsunami, as the quake causes great waves by pushing large volumes of water to the surface.

Tsunamis can also be caused by underwater volcanic eruptions. Volcanic eruptions are another natural disaster, and they are caused by magma escaping from inside the earth. An explosion takes place, releasing the magma from a confined space, which is why there are often also huge quantities of gas and dust released during a volcanic eruption. The magma travels up the inside of the volcano, and pours out over the surrounding area as lava.

It is true that a natural disaster is a natural process and we cannot stop it but by making certain preparations, we can reduce the magnitude of the loss to life and property. First of all we should reduce global warming which is the root cause of all the problems. We should also have insurance policies so that we could have sufficient money to rebuild our lives after any such disaster. Scientists should invent advanced warning systems. While construction we should make sure that it is strong enough to withstand earthquakes. We should educate people about evacuation during any disaster.
