Understanding Disaster Management Phases and Actions
Disaster management is a critical process involving several phases aimed at reducing risks, preparing for, responding to, and recovering from disasters. The question asks us to identify which specific action is incorrectly paired with its corresponding disaster management phase. Let's break down the typical phases and analyze the options provided.
The Major Phases of Disaster Management
Generally, disaster management encompasses the following key phases:
- Mitigation/Prevention: Actions taken to eliminate or reduce the long-term risk to human life and property from hazards. This includes efforts to prevent disasters or lessen their impact.
- Preparedness: Planning, training, and educating for emergencies. This phase involves developing plans, stockpiling resources, and conducting drills to ensure readiness.
- Response: Actions taken immediately before, during, and directly after a disaster occurs to save lives, reduce health impacts, ensure public safety, and meet basic human needs.
- Recovery/Rehabilitation: Actions taken to assist communities affected by a disaster in rebuilding structures, restoring services, and revitalizing the economy and social well-being. This phase focuses on returning to normalcy and improving resilience.
Analyzing the Options
Now, let's examine each option in the context of these phases:
Option 1 Analysis: Pre-disaster: rehabilitation and recovery of victims
The terms rehabilitation and recovery refer to the processes of helping affected populations and areas rebuild and return to normal after a disaster has occurred. These actions clearly belong to the post-disaster phase, not the pre-disaster phase. Therefore, this pairing is mismatched.
Option 2 Analysis: Post-disaster: capacity-building for future resilience and strengthening coping mechanisms
Capacity-building and strengthening coping mechanisms are essential parts of the recovery phase. By learning from past events and improving infrastructure, community programs, and individual preparedness, a community becomes more resilient to future disasters. This pairing is appropriate.
Option 3 Analysis: During disaster: evacuation of people, setting up shelters and relief camps
Evacuation, establishing shelters, and setting up relief camps are immediate actions taken to protect lives and provide essential support when a disaster strikes or is imminent. These are core components of the response phase, which occurs during and immediately after a disaster. This pairing is correct.
Option 4 Analysis: Pre-disaster: preparing vulnerability zoning maps and spreading public awareness
Creating vulnerability zoning maps helps identify areas at high risk, allowing for targeted mitigation and planning. Spreading public awareness educates citizens about potential risks and preparedness measures. Both are proactive measures taken well before a disaster occurs, fitting perfectly into the pre-disaster (mitigation and preparedness) phase. This pairing is correct.
Conclusion on Mismatched Action
Based on the analysis, the action of rehabilitation and recovery of victims is incorrectly associated with the pre-disaster phase. These crucial activities are fundamental to the post-disaster recovery period.

A stone is thrown horizontally from the top of a 20 m high building with a speed of 12 m/s. It hits the ground at a distance R from the building. Taking g = 10 m/s2 and neglecting air resistance will give :
A sphere of volume V is made of a material with lower density than water. While on Earth, it floats on water with its volume f1V (f1 < 1) submerged. On the other hand, on a spaceship accelerating with acceleration a < g (g is the acceleration due to gravity on Earth) in outer space, its submerged volume in water is f2V. Then:
A railway wagon (open at the top) of mass M1 is moving with speed v1 along a straight track. As a result of rain, after some time it gets partially filled with water so that the mass of the wagon becomes M2 and speed becomes v2. Taking the rain to be falling vertically and the water stationery inside the wagon, the relation between the two speeds v1 and v2 is :
Consider the following statements:
1. Distance between the longitudes becomes zero on North Pole and South Pole.
2. Distance between the longitudes is maximum on the Equator.
3. Number of longitudes is more than number of latitudes.
Which of the statements given above is/are correct?
One block of 2⋅0 kg mass is placed on top of another block of 3⋅0 kg mass. The coefficient of static friction between the two blocks is 0⋅2. The bottom block is pulled with a horizontal force F such that both the blocks move together without slipping. Taking acceleration due to gravity as 10 m/s2, the maximum value of the frictional force is :
