Natural Disasters and Their Management - Class IX

The Ganges river system, particularly its northern tributaries originating in the Himalayas, is the primary cause of frequent flooding in the plains of Uttar Pradesh.

Forests naturally absorb water from rainfall and slowly release the water into the rivers. After deforestation, rainfall flows too quickly to the rivers, stripping the topsoil and causing erosion and flooding to occur. When these floods break the river's banks, further problems arise as the path of the river changes and further soil erosion occurs along the river's new path. Deforestation also makes an area more arid, contributing to droughts.

A flood is an overflow of water that submerges land, which is classified as a natural disaster caused by meteorological or hydrological events.

Flash floods are defined by the speed of flooding, not the source or location of flooding. While flash floods are often caused by heavy rainfall, they can also result from other events, such as drain blockages and cloud bursts

A flood is an overflow of water that submerges land which is usually dry. The European Union (EU) Floods Directive defines a flood as a covering by water of land not normally covered by water. In the sense of "flowing water", the word may also be applied to the inflow of the tide.

Floods are complex events that can vary significantly in their physical characteristics, including the volume of water (size), the velocity of the current, and the duration of the inundation.

Global meteorological studies generally categorize the world into four major cyclone-prone zones based on the frequency and intensity of tropical storms.

Amritsar is least likely to be affected by a cyclone because the city does not lie near to any coastal area. In India the cyclones generally affect the coastal areas.

Prior planning will help the effects of the storm to be less, reduce potential loss of life and property, and help you to recover faster.

1. Preparedness is a continuous cycle of planning, organizing, training, equipping, exercising, evaluating, and taking corrective action. Training and exercising plans is the cornerstone of preparedness which focuses on readiness to respond to all-hazards incidents and emergencies.
2. Mitigation is the effort to reduce loss of life and property by lessening the impact of disasters and emergencies. Mitigation involves structural and non-structural measures taken to limit the impact of disasters and emergencies.

The three phases of disaster management include:

1. Preparedness 
2. Response 
3. Recovery

The term 'Willy-willy' is a colloquial name used specifically for tropical cyclones that occur in the north-west region of Australia.

The Himalayan mountain region is located along a major tectonic plate boundary (the collision zone between the Indian and Eurasian plates), making it one of the most seismically active and earthquake-prone areas in the world.

According to geographical and disaster management statistics in regions like India, approximately 68 to 70 percent of the cultivable land is vulnerable to drought conditions due to erratic rainfall and dependence on monsoons.

Rajasthan.

Droughts is expected to result in increased displacement is the area of so-called slow-onset disaster in which climate change has specific long-term environmental effects over time such as desertification and other changes in weather patterns, which means that people’s livelihoods are no longer sustainable and they are forced to migrate to other places.

Drought is a prolonged period of deficient rainfall, which directly leads to crop failure and reduced agricultural productivity.

All the listed actions (taking cover under sturdy furniture, staying away from hazards, and stopping a vehicle in a safe location) are recommended safety measures during an earthquake.

Panic, attempting to catch falling objects, and using elevators are all dangerous actions during an earthquake. Therefore, all of these should be avoided.
