This was the case for the natural disasters essay conclusion large earthquakes-a magnitude 6. First, check for injuries. Next, check the gas and electric lines, and turn them off if you can do so safely. And if you are inside a heavily damaged structure, get yourself and others out as soon as possible. Protect your mouth, nose, and eyes from the dust and call or text for help.

But if you are outside, keep an eye out for hazards like fallen electrical lines, ruptured gas pipes, or precarious structures. Turn on the radio-perhaps one you stowed natural disasters essay conclusion your earthquake emergency kit-and listen for updates. Heed warnings and instructions from official organizations like the United States Geological Survey, and be careful about what you see shared on social media.

Falsehoods spread like wildfire in emergency situations. The unpredictability of earthquakes is frightening, but with a little preparation, you can be ready identity paper example a big one strikes.

Introduction Tsunami is a series of ocean waves typically caused by large undersea earthquakes or volcano eruptions at tectonic plate boundaries.

Results and Discussion 3. Lessons Learned from Tsunami To prevent the devastating effects of future tsunami, these islands of Indian Ocean have set their priorities in achieving 3 goals [ 5 ]: i development of disaster tsunami program which include implementation of tsunami program at national level, natural disasters essay writing, and international levels and coordination of all these programs, ii development of an Indian Ocean early warning system, iii development of tsunami research program.

National Level The most studied plans are the Madagascar plan, the tsunami early warning and response system in Mauritius, and the creation of the Department of Risk and Disaster Management in Seychelles.

Regional Level Disaster management is a regional priority in the Indian Ocean due to permanent threat of cyclones, floods, and tsunamis. Future and Challenges The main challenge for all the islands of the Indian Ocean is to coordinate all the national efforts with existing regional and international endeavors to meet their stated priorities before the next tsunami events.

The role of one special group of physicians should be mentioned at all these levels. Conclusion This paper is the first peer-reviewed paper on the impact of the tsunami on the islands bordering the Indian Happy essay and the lessons learned from this event from national, regional, and international organizations to prevent such events from occurring again in the future.

Buildings such as schools, hospitals, offices, etc. Floods are one of the most common natural disasters occurring in many parts of the world every year. Floods occur due to heavy rainfall within a short duration of time in a particular region which causes the rivers and streams to overflow. Since most of the precipitation occurs within span of two to three months during the rainy season, most floods occur during that time.

The floods in the mountainous regions due to cloudbursts or damming of streams are referred to as flash-floods. In flash-floods, the water drains away quickly but only after causing extensive damage.

The plain areas of a region which are drained by a number of rivers, are the places most affected by floods. The Ganga and Brahmaputra rivers and their tributaries are most susceptible to floods. However, heavy rains cause occasional floods in parts of Gujarat, Maharashtra, Karnataka and Tamil Nadu. Flooding, in India, is a major problem and some part or the other is affected by the fury of floods usually during the months from July to September.

Floods cause untold miseries to the affected regions in the form of huge losses of life and property. There is great damage to agriculture and livestock. Flood affected areas face acute shortages of food and drinking water. Besides, floods cause a number of water borne diseases such as diarrhea, gastroenteritis, jaundice, malaria, etc. Though the lives lost in floods may not be as high as in case of earthquakes or cyclones, the damage to the environment is immense.

The problem is further aggravated if the floods last for a longer duration of time. Floods not only damage property and endanger if lives of humans and animals, but have other effects as well, such as:. Manmade structures like buildings, bridges, roads, sewer lines, power lines, etc. Though floods are a natural hazard, it is sometimes intensified due to undesirable human activities.

Natural disasters essay conclusion measures that can be taken to control the extent of flood damage include land use planning, building of physical barriers, preventing human encroachment and use of technology for relief.

Afforestation on the upper reaches of the river catchment areas to control soil erosion and excessive runoff. Drought is a condition of abnormally dry weather within a geographic region.

Natural Disasters on Earth: Essay on Natural Disasters (9069 Words)

Drought refers to the lack or insufficiency of rain for an extended period of time in a specific region. During droughts, rainfall is less than normal causing a water imbalance and resultant water shortage. It occurs when the rate of evaporation and transpiration exceeds precipitation for a considerable period.

Drought should not be confused with dry climate, as in the Sahara or Thar Desert. It is marked by an unusual scarcity of water and food for the humans as well as animals.

Dealing with Natural Disasters: Listen and Write

Certain regions of the world, such as parts of Central Africa, are characterized by low amount of rainfall resulting in perennial drought-like conditions. Some part of India is often affected by drought even during the rainy season.

As India is primarily an agricultural country, droughts cause untold miseries to the common people. Many Indian farmers are still totally dependent on rainfall for irrigation and because of abnormally dry spells there is extensive crop damage.

However, sometimes drought-like conditions also prevail in the Gangetic Plain also. The severity of the drought is gauged by the degree of moisture deficiency, its duration, and the size of the area affected. If the drought is brief, it is known as a dry spell or partial drought. Soil degradation and erosion occurs. Soil cracks because of shrinkage during desiccation Fig.

Rains are caused by a number of natural factors like air currents, wind direction, etc. Thus, droughts are a natural phenomenon, beyond human control and prevention. Though, global warming may have changed the pattern of rainfall in the recent times. In modem times, by the use of satellites, we can predict the weather pattern over a particular area. Drought-like conditions can be overcome by better water harvesting techniques. Certain precautions can be taken in drought prone areas, which relate to management of water resources, proper agricultural techniques and relief by different agencies.

Proper irrigation techniques, such as drip and trickle irrigation that natural disasters essay conclusion the use of water. Cyclone is an area of low atmospheric pressure surrounded by a wind system blowing in anti-clockwise direction, formed in the northern hemisphere.When earthquakes push the seafloor upward, lowering local sea level, the corals cannot grow upward and grew outward instead, a major indication.

An area off Sumatra that has been the source of disastrous earthquakes, still carries a lot of pent-up pressure that could result in another strong quake, noted the study reported in the journal Nature. It is not, however, clear as of now whether a precise earthquake prediction and warning system can be developed and put to any effective use.

The greatest damage in an earthquake is caused by the destruction of buildings and resultant loss of life and property and destruction of infrastructure. The earthquakes having the same magnitude on the Richter scale may vary in damage from place to place.

The extent of damage that an earthquake can cause may depend on more than one factor. The depth of the focus may be one factor. Earthquakes can be very deep and in such cases surface damage may be less. The extent of damage also depends on how populated and developed an area is.

The National Buildings Organisation of India lists weaknesses in burnt brick buildings as follows:. Large openings placed too close to the corners. Conclusion natural disasters essay rooms having long walls unsupported by cross-walls. Some measures to prevent building collapse during the earthquake are: symmetry and rectangularity of building; symmetry in locating openings; simplicity in elevation or avoidance of ornamentation; intersecting internal walls so as to divide the total plan in square enclosures of not more than 6 m wide; use of steel or wooden dowels going into walls help with write college application essay good at corners shear walls or T-junctions to provide effective bonding; use of bond beam or band of reinforced concrete at lintel levels of openings and serving as lintel too.

The last one is the one feature that is most effective in ensuring the integrity of enclosures like a rigid box. For masonry construction, the BIS has specified that materials to be used should be well-burnt bricks and not sun-dried bricks. The use of arches to span over openings is a source of weakness and should be avoided unless steel ties are provided.

Scientists have suggested designing buildings to counter quake movement by shifting the centre of gravity with the help of a steel weight placed on the top of the buildings.

In this technique, thick, columns of concrete and steel are inserted metre deep into the soil beneath the regular foundation. In case of earthquakes, these pillars provide extra strength and natural disasters essay writing the buildings from collapsing. During a quake, the rubber absorbs the shocks. In high-rises, enlarged structures on the top floors should be avoided. Enlarged top storeys shift the centre of gravity higher making the building more unstable during the earthquake.

In cities, many buildings stand on columns. The ground floor is generally used for parking and walls start from the first floor. These buildings collapse quickly during an earthquake. It is associated with fierce wind and heavy rainfall. Horizontally it extends from to km and vertically from the surface to about 14 km.

Severe tropical cyclones cause considerable damage to property and agricultural crops. The principal dangers posed are: a fierce winds; b torrential rains and associated flooding; and c high storm tides combined effect of storm surge and tides. Rainfall up to 20 to 30 cm a day is common. The highest ever sustained winds recorded in the case of tropical cyclones are kmph. Storm surge rise of sea level of four metres are common. The highest sea level elevation in the world due to continued effect of storm surge and astronomical high tide occurred in near Bakerganj, where the sea level rose by about 12 metres above the mean sea level on that occasion.

Tropical cyclones over the Bay of Bengal occur in two district seasons, the pre-monsoon months of April-May and the post-monsoon months of October-November. On an average, in fact, almost half a dozen tropical cyclones form in the Bay of Bengal and the Arabian Sea every year, out of which two or three may be severe.

Out of these, the stormiest months are May-June, October and November. Compared to the pre- monsoon season of May, June, when severe storms are rare, the months of October and November are known for severe cyclones. The IMD has published the tracks of the cyclones since and updates them every year in its quarterly scientific journal, Mausam. As 90 per cent of the deaths in severe cyclones all over the world occur in high storm surges accompanying them, the only feasible method to save the lives of human beings and animals is to evacuate them to safe inland cyclone shelters as early as possible after the receipt of advance cyclone natural disasters essay conclusion from the IMD.

The evacuation of people is difficult in flat coastal districts as in Bangladesh where the tides of six to 10 metres above the sea level submerges offshore islands and travels inland for considerable distances.

Conclusion natural disasters essay

This is a narrow belt at the equator, where the trade winds of the two hemispheres meet. It is a region of high radiation energy which supplies the necessary heat for the vaporisation of sea water into the air. This moist unstable air rises, generates convective clouds and leads to an atmospheric disturbance with a fall in surface atmospheric pressure. This causes a convergence of surrounding air towards this region of low pressure.

The converging mass of air gains a rotary motion because of what is known as the Coriolis force caused by the rotation of the Earth. However, under favourable circumstances, such as high sea-surface temperatures, this low pressure area can get accentuated.

The convective instability builds up into an organised system with high-speed winds circulating around the low pressure interior.

Essay on natural disaster

The eye has an average radius of 20 to 30 km. It can even be as much as 50 km. Given the existing scientific knowledge about cyclones, it is not yet possible to physically dissipate the buildup of a massive cyclone. Cures are generally worse than the disease. For example, while seeding by sodium iodide crystals has been attempted in some parts of the world- with marginal success-a more effective prescription proposed sometimes is a nuclear explosion.

Obviously, that would be trading one disaster for an even greater one. Accepted technology, therefore, only provides the capability to detect and track cyclones with sophisticated satellite imagery and ground- based radar systems.

But here too the limitations are conclusion natural disasters essay. Atmospheric science, for example, is not yet in a position to unambiguously predict the motion and behaviour of a cyclone more than 24 hours ahead of its arrival. So all that is possible in that brief span is to warn the vulnerable sections of the population of the imminent danger and adopt measures to move them to safer cyclone withstanding structures.

Essays on leadership frequency, intensity and coastal impact of cyclones varies from region to region. Interestingly, the frequency of tropical cyclones is the least in the north Indian Ocean regions of the Bay of Bengal and the Arabian Sea; they are also of moderate intensities.

But the cyclones are deadliest when they cross the coast bordering North Bay of Natural disasters essay writing coastal areas of Orissa, West Bengal and Bangladesh. This is mainly due to storm surges tidal waves that occur in this region inundating the coastal areas. Over the last two-and-a-half centuries, 17 of the 22 severe tropical cyclones-each causing loss of more than 10, human lives-took place in the North Bay of Bengal. While gales and strong winds, as well as torrential rain, that usually accompany a cyclone can cause sufficient havoc to property and agriculture, loss of human life and cattle is mainly due to storm surges.

If the terrain is shallow and shaped like a funnel, like that of Bangladesh-much of the exposed land is just about at the mean sea level or even less-storm surges get enormously amplified. Coastal inundation due to a combination of high tide and storm surge can cause the worst disaster.

India has an efficient cyclone warning system. Tropical cyclones are tracked with the help of i regular observation from weather network of surface and upper air observation stations, ii ships report, iii cyclone detection radars, iv satellites, and v reports from commercial aircraft.

Ships of merchant fleet have meteorological instruments for taking observations at sea. The range of these radars is km. When the cyclone is beyond the range of coastal radars, its intensity and movement is monitored with weather satellites. Warnings are issued by the area cyclone warning centres located at Kolkata, Chennai and Mumbai, and cyclone warning centres at Bhubaneswar, Visakhapatnam and Ahmedabad. This consists of the following elements:. Typically, in a cyclone the maximum devastative effects are within about km from the centre and on the right of the storm track where all the islands lie.

Evacuating the population just 24 hours before would require an army of high speed boats, an unfeasible proposition for a resource-poor country. The obvious solution, therefore, would be to provide a large number of storm shelters in the particularly vulnerable areas. So inured are we to the annual phenomena of floods in season, that one more village practically washed away by a flash flood causes no more than a ripple.

But for the people there it is a traumatic experience. Earlier, it used to be done by a conventional method-gauge to gauge or discharge correlation by which future gauges at forecast points are estimated on the basis of gauge discharge observed at some upstream station. Gradually, other parameters like precipitation, etc. Nowadays, computer-based hydrological models are being used for inflow and flood forecasting. The basic information required for flood forecasting is rainfall data of the catchment area of the river.

Due to poor communication and inaccessibility, complete information is not always available. However, with sophisticated high-powered S-band radars, it is now possible to estimate the rainfall in an area of up to km around the radar site. This system is used extensively in the US for estimating the rainfall potential in the catchment areas of major rivers an issue of flood forecast warning.

The use of radar for the precipitation estimate is based on the principle that the amount of echo return from a volume of cloud depends on the number and size of hydrometeros in it.

The empirical relationship between the echo return and natural disasters essay writing rainfall rates has been developed for various types of rain. Using fast switching digital circuits, the return video is digitised, integrated, normalised and contoured into standard six or seven rainfall rates. Observations taken every ten minutes can be cumulatively added natural disasters essay writing averaged to give hour rainfall prediction over the region.

Through appropriate modes, the information from a number of radar sites can be sent to a central office where powerful computers process the data and yield the overall rainfall potential of the weather system. The advantage of using radars for hydrological work lies in the fact that the information over the inaccessible region is available conclusion natural disasters essay actual human intervention.

Of course, there are many assumptions which do not always hold good, thereby introducing large errors in the result. But with suitable calibration with actual gauge measurements correction factors could be applied. This has not helped much as population has moved into conclusion natural disasters essay where flooding used to occur and has been controlled due to structure.

Whenever flooding level is higher than what the structure can hold, the result is devastating. The non-structural approach calls for removing populations from the flood plains. Another important aspect is to reduce the silting of rivers. Afforestation in the catchment areas, along the river banks, helps in maintaining the effective river volume.

But it is evident that, macbeth imagery essay the last four decades or so, flood control efforts have proved counter-productive because they have not included adequate planning for conservation of watersheds.

As a result the increasing siltation of rivers is accelerating their rate of flow in flood, eventually forcing even well built embankments to give way. As is well known, embankments increase the force of the river by channelling natural disasters essay writing over a narrow area instead of permitting it to spread.

Natural disasters essay conclusion

The danger of relying too heavily on the system of embankments for flood control has been well documented. Apart from the depletion in forest cover, overgrazing contributes greatly to soil loss in the catchment areas. Even in the mountainous areas, where efforts have been made to plant trees on steep slopes to reduce the soil loss during rains, mountain goats have impeded the process of regeneration.

Cattle and goats also destroy the plant cover that springs up after the rain which is crucial for holding down the soil. Human activity is yet another factor. Quarrying, road construction, and other building activity in sensitive catchment areas add to the soil loss. As a result of all these factors, the silt load of many rivers has increased greatly. The siltation level of dams, which has generally been underestimated at the time of construction has had to be revised by 50 to per cent in some cases.

Siltation reduces the capacity of reservoirs. Consequently in order to save the dam, unscheduled and panic releases of water are resorted to often without giving adequate warning to people downstream who live in the path of the released water. Thus ironically dams built partly to assist in flood control, are today contributing to the devastation caused by floods. The phenomenon that really ought to engage the minds of planners is how and why the flood-prone area in the country is increasing each year.

Even areas which have never natural disasters essay writing floods in the past are now affected. The NFC estimates that 40 million hectares are flood-prone of which 32 million hectares can be protected.

Some such Centrally-sponsored schemes are: critical anti-erosion works in Ganga basin states, critical anti-erosion works in coastal and other than Ganga basin states, maintenance of flood protection works of Conclusion natural disasters essay and Gandak projects, etc. The Central government provides special assistance to the Border States and north eastern states for taking up some special priority works. A tsunami is a series of travelling ocean waves which are set off by geological disturbances near the floor of the ocean.

The waves of very, very long wavelengths and period rush across the ocean and increase their momentum over a stretch of thousands of kilometers. Some tsunamis may conclusion natural disasters essay as a tide but they are not tidal waves in reality. While tides are caused by gravitational influences of the moon, sun and the planets, tsunamis are seismic sea waves. However, it was triggered by unexpected natural disaster, the accident can be avoided if there exist a sound risk management cycle to identify the risks within this project and put a risk management plan in place.

There are three major key risk issues findings about the Fukushima Daiichi nuclear disaster. The first one is risk identification problems in risk…. Crowding and Population Displacement The Pan American Health Organization states that when disaster strikes, the impetus to seek relief, shelter, and treatment away from the disaster results in population movement, which inevitably results in crowding.

That is, some people may be particularly likely to turn to others to help resolve their uncertainty. Understanding who these individuals and groups are may help in designing more effective risk messages. In natural disasters essay writing of culture, research suggests that some cultures are more fatalistic than others when it comes to natural hazards Fatalistic attitudes may be underpinned….
