There are many different <br /><br />natural causes leading to natural disasters, and being aware of these causes enables us to be better prepared when they do arrive.<br />One of the most common natural disasters is flooding, which occurs when a river bursts its banks and the water spills out onto the floodplain. During wet periods, flood <br /><br />warnings are often put in place because of a great deal of heavy rain. There are other risk factors for flooding that we have to mention such as steep-sided channels cause <br /><br />fast surface run-off, the lack of vegetation and woodland break the flow of water. In other words, there is little to slow the floodwater down.<br />Earthquakes are another common natural disaster on the list that can cause many fatalities. Earthquakes are caused by the movements of the plates in the earth’s crust. These <br /><br />plates do not always move smoothly and can get stuck, and then cause a build-up of pressure – the reason why earthquake occur. In addition to this, an earthquake under the <br /><br />water can also cause a tsunami by pushing large volumes of water to the surface causing great waves.<br />Tsunamis can also be caused by underwater volcanic eruptions which are another natural disaster caused by magma escaping from inside the earth. An explosion takes place, <br /><br />releasing the magma from a confined space, and that is why huge quantities of gas and dust are always released during a volcanic eruption. Inside of the volcano, the magma <br /><br />travels up and then pours out over the surrounding area as lava.<br />Last but not least, one of the most common natural disasters that we commonly forgot is wildfires. They take place in many different countries all over the world, particularly <br /><br />during the summertime, and can be caused by a range of different reasons. Some of the things starting the wildfires can be totally natural, while others can be manmade, but <br /><br />the speed they spread is entirely down to nature. There are two main natural causes of wildfires which are the sun’s heat and lightning strikes. Other reasons are campfires, <br /><br />smoking, fireworks and many other things caused by humans. The reasons why they spread so quickly are prolonged hot, dry weather, where the vegetation dries out, which is why <br /><br />they often take place in woodland.
