iv. So they will travel at high speeds in deep waters and travel great distances as well losing little energy. Article 4 (800 words) on natural disasters. Disaster can be defined as a tragic event, such as accidents, fire, terrorist attacks, or explosions, etc., due to which people have to face heavy damage. The various types available for dissemination of disaster warning as well as arranging mitigation are: (a) land line links; (b) underground cable links; (c) wireless links; (d) microwave (LOS); and (e) satellite links. One is the availability of an effective technique to forecast the disaster with its extent and the other is effective communication of the same to the civil authority responsible for rescue operations. People who live in snowy mountains always have fear of it. It has decided to set up a sophisticated system for detecting deep sea movements and develop a network with the countries in the Indian Ocean region for sharing information on tsunamis. The most important is the early warning systems. Each day there are about 1,000 very small earthquakes measuring 1 to 2 on the Richter scale. The sudden release of stored elastic energy causes earthquakes. Thus India has four such zones now—II, III, IV and V. There is thus no part of the country that can be termed earthquake free. But preventive measures can be taken to reduce the damage from these disasters. These beams are shot from an observatory to a geostationary satellite in space. Tsunami attacks can come in different forms depending upon the geometry of the seafloor warping that first caused the waves. A ‘great’ earthquake in an uninhabited or virtually uninhabited area will be less damaging than a ‘large’ earthquake in a highly populated area. Vast areas of the country do not have telephone/ telegraph links. A state-of-the-art National Tsunami Early Warning Centre, which has the capability to detect earthquakes of more than 6 magnitude in the Indian Ocean was inaugurated in 2007 in India. Quarrying, road construction, and other building activity in sensitive catchment areas add to the soil loss. Of course, there are many assumptions which do not always hold good, thereby introducing large errors in the result. The National Building Code was also revised, taking into consideration the natural hazards and risks of various regions of India. Moreover, they can cause greater damage if they occur in colonial states. ii. The largest earthquake in India was in Calcutta in 1737, in which 3 lakh people were casualties. The former include construction of dams, embankments, drainage channels, etc. Here we are providing Paragraph on Natural Disaster in English Langauge for student & competitive Examiner with various word boundaries such as 300, 500, 600 and 800 words, as per your requirement select the article. 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. Content Filtrations 6. Winners Do Everything in a Right Way - Story With Moral, List of Awards Given by Indian Government. TOS ◀▶ The theory of plate tectonics offers a comprehensive explanation for several geological phenomena — continental drift, mountain building and volcanism, and, of course, earthquake. Since P waves travel at a speed of about 8 km per second and S waves at 5 km per second, it is possible to compute the distance of their origin from the seismic record. The high seismicity region extends from Hindukush in the west to Sadiya in the northeast which further extends down to the Andaman and Nicobar Islands. Regardless of all these measures by the government, awareness for effective disaster management is the first condition in which the relief agencies can be brought to the affected areas immediately. This Act provides for the creation of similar funds on a National Disaster Response Fund and National Disaster Mitigation Fund and at the state and district levels. This was the first experience of a disaster like a tsunami in India. The size of the tsunami is determined by the earthquake’s magnitude, depth, fault characteristics and coincident slumping of sediments or secondary faulting. Moreover, this causes extreme damage to anything that comes in its way. This could be extended to the entire earthquake/ flood prone areas. DART-type gauges will be installed by the government and it will join 26 countries in a network that warn each other about tsunamis. A Tsunami can consist of multiple waves. Under this, under the leadership of the National Disaster Management Authority and the Chief Ministers under the leadership of the Prime Minister, there is a provision for the establishment of District Disaster Management Authority under the chairmanship of State Disaster Management Authority and District Judges. The Deep Ocean Assessment and Reporting System (DOARS) will be set up six kilometers deep under the sea. This will be supplemented by activities under various other national/state level mitigation projects. Moreover, the can also cause landslides, avalanches, and Tsunami. Greater the vertical displacement, greater will be the wave size. The warning of an oncoming tsunami cannot be obtained by merely detecting an earthquake in the seas; it involves a number of complex steps which have to be completed in a systematic and quick fashion. The December 26 earthquake and tsunami shifted the North Pole by 2.5 cm in the direction of 145 degrees East longitude and reduced the length of the day by 2.68 microseconds. The epicentre lies where the circles intersect. For, just a year later in 1976, the seismologists could not predict the Tangshan earthquake. 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. Disasters can be both man-made and natural. The National Flood Commission (NFC) was set up specifically to deal with the problem of floods. Flood forecasting in India commenced in 1958 with the establishment of a unit in Central Water Commission (CWC). Animals in Andhra Pradesh, Rajasthan and West Bengal have to suffer the worst of these disasters. In 2003, however, BIS redefined the seismic map of India by merging zones I and II. 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. After any natural calamity, money is needed to rebuild life again. One of the reasons for this region being prone to earthquake is the presence of the young-fold Himalayan Mountains here which have frequent tectonic movements. The ground floor is generally used for parking and walls start from the first floor. At 6000 m, it travels at 873 Ion per hour. The Method of Splitting Tsunami (MOST) constitutes computer models developed by the NOAA which can simulate the generation of a tsunami and its inundation of dry land. Tsunamis have been known to occur suddenly without warning. Warnings are issued by the area cyclone warning centres located at Kolkata, Chennai and Mumbai, and cyclone warning centres at Bhubaneswar, Visakhapatnam and Ahmedabad. Observations taken every ten minutes can be cumulatively added and averaged to give 24-hour rainfall prediction over the region. Based on intensity and frequency of occurrence, world map is divided into the following earthquake zones or belts—, Circum-Pacific Belt Surrounds the Pacific Ocean and accounts for more than three-fourths of the world’s earthquakes. Subduction zones off Chile, Nicaragua, Mexico and Indonesia have created killer tsunamis. Specific developmental schemes for prevention and mitigation of disasters. The behaviour of some animals is also believed to undergo a distinct change prior to an earthquake. Moreover, these waves have a high current. That is, they are related to an earthquake- related mechanism of generation. ii. Evacuating the population just 24 hours before would require an army of high speed boats, an unfeasible proposition for a resource—poor country. This bill was enacted on December 23, 2005. The sensors will be linked to the satellite that will relay information to the earth station. The empirical relationship between the echo return and the rainfall rates has been developed for various types of rain. ii. In August 2010, about 113 people were killed due to cloudburst in Jammu and Kashmir's Leh. The Bureau of Indian Standards issued building codes for construction of different types of buildings in different seismic zones in India. This is because as the depth of the water decreases, the speed of the tsunami reduces. Moreover, landslides can cause destruction to man-made things in many ways. The severity or degree of damage can be further divided into three categories: Small Scale Disasters: Small scale disasters are those that extend from 50 Kms. Large Scale Disasters: These disasters cover an area of more than 1000 Kms. xi. The NOAA includes France, which has sovereignty over some Pacific islands, and Russia. With decrease in speed, height of the tsunami wave grows. Some tsunamis may appear as a tide but they are not tidal waves in reality. A tsunami can cause floods if it occurs near shores. One relates to the so- called seismic gaps, which postulates that great earthquakes rupture the Himalayan arc whose total length is about 1700 km. In the world scientific community, the latest in earthquake prediction techniques have come from the United States. Moreover, they can also occur from earthquakes and volcanic eruptions. These can neither be provided in a short span of time available for mitigation nor are there resources to do so. During a quake, the rubber absorbs the shocks. Experience has shown that it remains completely unaffected under the severest cyclonic condition. These processes together create propagating waves. (When an earthquake occurs along a fault line within the plate, it is called an intra-plate earthquake. Parts of the ocean floor then snap upward and other areas sink downward. If we look at the disasters that have taken place earlier, we can easily say … The increasing need of water is constantly reducing the level of groundwater, as well as the industrial toxic solvents are being sown in rivers, which is causing our water to become contaminated. By providing the basic information necessary for the rescue of people in the disaster areas, the damage caused by disasters can be reduced as far as possible. viii. Join courses with the best schedule and enjoy fun and interactive classes. Hope you like everyone, please share your classmate too. II. Due to increase in urbanization and industrialization, improper exploitation of water resources is happening. The Pacific among the oceans has witnessed most number of tsunamis (over 790 since 1990). Outside the framework of Plan schemes, many innovative measures will also be adopted to encourage disaster risk reduction measures in the corporate sector, non-government organisations, and among individuals. However, the center of an earthquake falls mostly offshore. Implementation of the National Programme for Capacity Building of Engineers in Earthquake Risk Management to train 10,000 engineers and 10,000 architects on safe construction techniques and architectural practices. It is administered by the National Oceanic and Atmospheric Administration (NOAA). Due to the decrease in the amount of rainfall, it becomes dry. I have been blogging for 3 years and through the Fast Read.in I have been giving important educational content as far as possible to the reader. Many regions in India are highly vulnerable to natural and other disasters on account of geological conditions. In some phenomena, such as cyclones, flood, etc. These cause the most severe damage to the environment. Severe tropical cyclones cause considerable damage to property and agricultural crops. The 12-point Mercalli scale measures the intensity of shaking during an earthquake and is assessed by inspecting the damage and interviewing survivors of the earthquake. For effective two way communication, VHF/UHF links should be established from every earth station to the affected zone. In most cases ‘flooding’ is caused by a river over-spilling its banks due to (a) excessive precipitation, (b) obstruction in the river bed, (c) inadequate waterways at rail/road crossings, (d) drainage congestion, and (e) change in river course. But the cyclones are deadliest when they cross the coast bordering North Bay of Bengal (coastal areas of Orissa, West Bengal and Bangladesh). The scale starts at one and has no upper limit. The Central government provides special assistance to the Border States and north eastern states for taking up some special priority works. The human-activity-induced hazards like pollution and global warming have already started showing their precursors, giving sufficient time to control and avoid these hazards by long term planning. In the ‘base isolation technique’, heavy blocks of rubber and steel are put between the foundation and the building. Report a Violation, Essay on Tsunami: About, Propagation and Occurrence of Tsunami, Few Tips to Apprehend the Danger of Tsunamis, The Objectives and Observation of Ocean Development around the World. Due to the rapidly growing population, the need for humans has increased and consumerism has increased in them. Fiscal measures like rebates on income and property tax for retrofitting unsafe buildings, compulsory risk insurance for bank loan on all types of properties will also be introduced to mobilise resources for safe construction and retrofitting of existing constructions in all disaster prone areas. Modules have also been identified to include disaster management aspects in the course curriculum for engineering, architecture, and medical degrees. When there was a flood in Uttarakhand in 2013, no disaster management plan could be implemented here. The highest sea level elevation in the world due to continued effect of storm surge and astronomical high tide occurred in 1876 near Bakerganj, where the sea level rose by about 12 metres above the mean sea level on that occasion.
