natural hazards notes

Release of heat also affected by amount of water in the environment There are three stages involved in disaster mitigation and management: (i) Pre-disaster management involves 1. generating data and information about the disasters, 2. preparing vulnerability zoning maps, 3. spreading awareness among the people about the disasters, 4. disaster planning, 5. preparedness and preventive measures are other steps that need to be taken in the vulnerable areas. The revision notes covers all important formulas and concepts given in the chapter. Ecological conditions. Share via Facebook Share via Mail Share via WhatsApp NH: counterclockwise SH: clockwise In other words when the hazardous threat actually happens and harms humans, we call the event a natural disaster. Ground water, 5. rainfall in the next 12 hours Latent Heat of Fusion. initial conditions or models 5. radiation is absorbed by the planet heats the planet. Natural hazards in Tamilnadu Introduction Natural disasters are consequences of a natural hazard like an earthquake, landslide, cyclone, flood, or tsunami which affects human activities. 1. Drought is a complex phenomenon as it involves elements of meteorology like 1. Natural Hazards are naturally occurring physical phenomenon caused either by rapid or slow onset events which can be Geophysical- Earthquakes, landslides, tsunamis and volcanic activity Hydrological- Avalanches and Floods Climatological- extreme temperatures, drought and wildfires Meteorological- Cyclones and storms Moreover, if an area has more than 30 per cent of its gross cropped area under irrigation, the area is excluded from the drought-prone category. Kinetic energy Though most of the cyclones originate between 10-15 north latitudes during the monsoon season, yet in case of the Bay of Bengal, cyclones mostly develop during the months of October and November. Table 7.3: Effects of Earthquakes. Not always uniform. Natural Hazards (and the resulting disasters) are the result of naturally occurring processes that have operated throughout Earth's history.

OCR GCSE Geography, AQA A Level Geography Human vulnerability to disasters is increased by poverty and the risk potential for disasters. Meanders and fluctuates Subsidence. Areas of India frequently affected by floods Rashtriya Barh Ayog (National Flood Commission) identified 40 million hectares of land as flood- prone in India. It is more in the shallow water than in the ocean deep. On the basis of severity of droughts, India can be divided into the following regions: Extreme Drought Affected Area:Most parts of Rajasthan, particularly areas to the west of the Aravali hills, i.e.. Marusthali and Kachchh regions of Gujarat fall in this category. Tsunamis are frequently observed along the Pacific ring of fire, particularly along the coast of Alaska, Japan, Philippines, and other islands of Southeast Asia, Indonesia, Malaysia, Myanmar, Sri Lanka, and India etc. Warm water provides the energy to evaporate more water, that rises, condenses, releasing huge amounts of energy. LANDSLIDES: 1.landslides are largely controlled by highly localised factors. However natural forces are not only the causes of disasters, but also they can be caused by human activities. temperatures Natural Disasters 13:35 . normalize data points required - problem with rare/extreme . Energy is conserved in an isolated system temperature, Energy balance in energy as vapour form has higher energy state than liquid state. Shouldnt change very quickly.. robust Convection and conduction inefficient 1. Out of these, the first two zones had experienced some of the most devastating earthquakes in India. Vertical Temperature Profile- below Troposphere- temp decreases 6 per kilometer Pressure always squeezes the volume from outside The only difference between these two is the combination, intensity and frequency of the controlling factors. The Ozone layer around the earth, if, dwindles further may cause Health hazards including Cancers . Restriction on the construction and other developmental activities such as roads and dams, 2. The centre of the cyclone is mostly a warm and low-pressure, cloudless core known as eye of the storm. Hazard Note 106 summarises the research behind the new . Natural Hazards are naturally occurring physical phenomenon caused either by rapid or slow onset events which can be Geophysical - Earthquakes, landslides, tsunamis and volcanic activity Hydrological - Avalanches and Floods Climatological- extreme temperatures, drought and wildfires Meteorological - Cyclones and storms used to deform the ground Expansion causes cooling Adaptations have been made that allow this course to be successful in an online environment Activities will go from paper-based exercises to online, interactive exercises. Afforestation, 4. Storage of water, 7. To equalize pressure on the inside and outside: balloon has to expand (iii) Modifying the house types and building designs in the vulnerable areas and discouraging construction of high-rise buildings, large industrial establishments and big urban centres in such areas. (iv) Finally, making it mandatory to adopt earthquake-resistant designs and use light materials in major construction activities in the vulnerable areas. Moreover, natural-hazard phenomena in the Pacific region are focused to a considerable extent along the Pacific rim where energy and mineral resources and human activity related to resource development are concentrated. The best app for CBSE students now provides Natural Hazards and Disasters class 11 Notes Geography latest chapter wise notes for quick preparation of CBSE exams and school-based annual examinations. Windchill = bring in lower temperatures causes body temp to cool Modern changes in perception of natural disasters and hazards: There has also been a change in the perception of natural disasters and hazards. rapidly Hydrological Drought: It results when the availability of water in different storages and reservoirs like aquifers, lakes, reservoirs, etc. Need revision notes and resources for other subjects? Previously hazards and disasters were seen as two closely associated and interrelated phenomena i.e. Nudity or sexual content Hateful, harmful, violent, or abusive content . Evaporation, 3. Construction of flood protection embankments in the flood-prone areas, 2. The State of Punjab suffers mainly from two natural hazards, namely, flood and earthquakes, of which floods have quite a high frequency of occurrence, whereas earthquakes of M > 5.0 have a moderate frequency within and close to the boundary of the State.
