Natural Calamity

Natural outbreaks come as a threat to humans. Thus, a crisis is a natural or anthropogenic terrible event in which bodily injury, loss of human life, loss of property, contaminated environment, loss of livelihood. It is known by humans in many forms like crisis, disaster, disaster, disaster etc. The common meaning of disaster is crisis or calamity, which is the English synonym 'disaster', derived from the French word 'desastre', meaning - evil or evil star. We often use the words natural hazard and natural disaster in the same sense, but there is enough difference between these two words. The occurrence of a physical event at a certain place, which is likely to cause harm, is known as a natural hazard; Such as earthquake, landslide, instant flood, avalanche cloud burst etc. Natural disaster refers to those natural events which are destructive to humans and destroy the entire social structure and the existing system. (A) Earthquake earthquake is one of the internal forces of the ground. There are vibrations every day in Bhagarth. But when these vibrations are very intense, they are called earthquakes. Generally, an earthquake is a natural and accidental event, which causes movement or ripple in the ground.Geologists have explained the causes of earthquakes due to volcanic eruptions, dislocation in the equilibrium, aquatic loads, shrinkage of the terrain, plate tectonics, etc. Earthquake is a natural disaster that is not under human control. Humans have succeeded in predicting earthquakes only and reducing the damage to property to some degree. Volcanoes are a surprising and devastating natural phenomenon. It is a cervix (crater or hole) that appears on the earth's surface which is related to the geology. The hot lava melted. New rocks and very hot gases are released from time to time. Substances emanating from this would collect as cones on the surface. Are called volcanic mountains. Volcano is an accidental and natural phenomenon which is not under human control. Slipping or falling as an entire part of the land or its fragmented and dissected sections is called ejaculation. These are also one of the major natural disasters. In the mountainous regions of India, landslides are a widespread natural disaster. Landslides occur as a result of a combination of many natural and anthropogenic factors. Increasing the vegetative cover is the most effective, inexpensive and useful way to control it, as it prevents soil erosion.A cyclone is also an atmospheric disturbance. Cyclone literally means - circular winds. Variation of air pressure occurs in the atmosphere. At higher speeds, the state of the atmosphere becomes unstable and a disturbance is produced. The diameter of cyclones can range from hundreds of miles to thousands of miles. Its speed can be more than hundred kilometers per hour. A cyclone is a weather related disaster. To inhibit its velocity, trees should be planted in the path of its arrival, whose roots are strong and the leaves are sharp and thin. In floods, due to excess rainfall during the rainy season, the water of the rivers often breaks the embankments and spreads to the surrounding low-lying areas, thereby submerging those areas. This is called flood. Floods are a natural occurrence. Heavy monsoon rainfall and cyclonic rain are the main causes of floods. Waterways should be kept as straight as possible to avoid flood situation and dam construction should be done in artificial reservoirs and populated areas in flood prone areas. Sakha drought is a situation in which there is less rainfall than expected and normal rainfall at a place. It takes a terrible form in summer. It is a weather related disaster, which comes at a slower rate than any other disaster. Both nature and humans are the root causes of drought. Excessive grazing, deforestation, global warming, excessive use of all agricultural land and uneven distribution of rainfall lead to drought conditions. Pica reservation for the construction of green belts, water harvesting by artificial measures, interlinking of various rivers, etc. are the main measures for the prevention of drought. Sea waves: Sea waves sometimes take destructive form and their height is sometimes 15 meters and even more Extends more.  They destroy the settlements around the coast.  These destructive sea waves are called 'tsunamis'.  An earthquake occurs near or below sea level, causing a stir in the sea and this movement takes the form of a destructive tsunami.  It is not under human control to stop the generation of tsunami waves.  The life and property can be protected by detecting the movements in the sea floor and warning of it from time to time through the tsunameter.
