Geography students can play an important role in disaster management for tsunamis. They can help with preparedness by creating maps of vulnerable areas, raising community awareness, and developing evacuation plans. During a tsunami, they can assist with search and rescue efforts, first aid, and ensuring access to food and water. In recovery, geography students aid with tasks like debris cleanup, infrastructure rebuilding, and counseling. Overall, they contribute to reducing future impacts through activities like hazard identification, early warning systems, and public education.

3. WHAT IS DISASTER?
• A disaster is a serious disruption of the functioning of a community or a society
involving widespread human, material, economic or environmental losses and
impacts, which exceeds the ability of the affected community or society to cope using
its own resources.
• A sudden accident or a natural catastrophe that causes great damage or loss of life.

4. Types of Disasters
• Natural disasters ….
1. Agricultural diseases & pests
2. Drought and water shortage
3. Earthquakes
4. Extreme heat
5. Floods and flash floods
6. Hail
7. Hurricanes and tropical storms
8. Landslides & debris flow
9. Thunderstorms and lighting
10. Tornadoes
11. Tsunami
12. Wildfire
13. Winter and ice storms
14. Sinkholes etc…
• Man-Made and Technological Types of
Disasters….
1. Hazardous materials
2. Power service disruption &blackout
3. Nuclear power plant and nuclear blast
4. Radiological emergencies
5. Chemical threat and biological weapons
6. Cyber attacks
7. Explosion
8. Civil unrest etc.…
Disasters can take many different forms, both natural and man-made or
technological in nature – that can impact a community.

5. What is Tsunami
• Tsunami is one of the world's worst natural disasters that can hit a country. Tsunami mean
"harbor wave“; also known as a seismic sea wave. Tsunami is the devastating impact of seismic
sea waves & this series of water waves caused by the displacement of a large volume of a body of
water, generally an ocean.
• This large ocean wave that is caused by sudden motion on the ocean floor. Earthquakes, volcanic
eruptions and other underwater explosions (including detonations of underwater nuclear
devices), landslides, glacier calving, meteorite impacts and other disturbances above or below
water all have the potential to generate a tsunami.
• Tsunamis cause damage by two mechanisms: the smashing force of a wall of water travelling at
high speed, and the destructive power of a large volume of water draining off the land and
carrying a large amount of debris with it.

7. Effects of Tsunami
The effects of a tsunami depend on the characteristics of the seismic event that generated the
tsunami. The effects of a tsunami include such as…..
• Hitting the shoreline.
• Loss of human and animal life; increasing instant death, injury, illness
• Millions of dollars in financial loss.
• Psychological effects.
• Loss of livelihood.
• The effect of tsunamis is limited to coastal areas, their destructive power can be enormous and
they can affect entire ocean basins; the 2004 Indian Ocean tsunami was among the deadliest
natural disasters in human history with at least 290,000 people killed or missing in 14 countries
bordering the Indian Ocean.
• A permanent change to the landscape
• Devastating property damage.
• contamination of soil and water.
• Severe flooding causes to damages drain systems.

8. WHAT IS DISASTER MANAGEMENT?
• The Red Cross and Red Crescent societies define disaster management as the organization and
management of resources and responsibilities for dealing with all humanitarian aspects of
emergencies, in particular preparedness, response and recovery in order to reduce the impact of
disasters.
• DISASTER MANAGEMENT CYCLE Include some phases such as……

9. Role of students in
1.DISASTER PREPAREDNESS
• These activities are designed to minimize loss of life and damage. preparedness is
the very important vital role in disaster management cycle.

11. Cont.…
If there is a noticeable decline in the
water, away from the shoreline, this is
considered “nature’s tsunami warning”
and you should move away immediately.
building early warning systems.
Emergency communications systems.
Be aware of tsunami warning signs.
Planning how to respond Ex;
preparedness plans, warning systems.

12. Cont.……
• Help to removing people and property from a threatened location and by facilitating timely and
effective rescue, relief and rehabilitation.
• Consider taking a first aid course and learn survival skills.
• Tune to a radio station that serves our area and listen for instructions from emergency officials.
• Stay away from the beach – do not go down to watch a tsunami come -Move away from the
shoreline and to higher ground.
• reserves of food, equipment, water, medicines and other essentials are maintained in cases of
national or local disasters.
• Help to Identify any vulnerability and potential dangers & repair it.
• Learn how to turn off the gas and electricity or any other electrical equipment in your house.
• strengthening the existing weak structures.
• preparation of the disaster management plans at household and community level.
• Raise awareness programs: teach and training to survival techniques in the water through their
swimming and boating courses.
• Put Seminars , workshop, issue handbills, competition such as art, poem, essay writing etc…

13. • Help to make map like,
 Social mapping.
 Vulnerability mapping.
 Hazard mapping .
 Resource mapping.
Advice to don't store important documents in the basement. Keep them at a higher level
or protected area or safer place.
•Developing long-term and short-term strategies& public education.
•Help to prepared to survive on our own for at least three days. To do this, you should
prepare an emergency kit for your home and car, along with a movable one.

14. Cont.…..
• Common preparedness measures include:
 The Communication plans with easily understood terminology and chain of
command.
 Development and practice of multi-agency coordination and incident command.
 Proper maintenance and training of emergency services.
 Development and exercise of emergency population warning methods combined
with emergency shelters and evacuation plans.

• These should blend with development activities, such as building human resources
for health and developing policies and practices to avoid similar situations in future.
• Information resources and services include data collection related to rebuilding, and
documentation of lessons learned.
• sustainable development.

18. Disaster prevention:
Prevention is defined as those activities taken to prevent a natural phenomenon or identify
potential hazard from having harmful effects on either people or economic assets. A tsunami
cannot be prevented or precisely predicted but can be reduced through community
preparedness.
 Early Warning Systems .
hazard identification (identifying the actual threats facing a community)
vulnerability assessment (evaluating the risk and capacity of a community to handle the
consequences of the disaster).
Grows mangrove in coastal region.
Identify the area which is tsunami risks zone.
Creating a map such as social mapping, resource mapping, vulnerability mapping, safe &
opportunity mapping.
Building stock assessment.
Awareness combine.
Training
Establish the social service department.
Maintaining and operating early warning towers and other early warning dissemination
equipment's.
 Distribution of early warning messages and ensure the reception at remote vulnerable
villagers.

19. Mitigation
Mitigation activities actually eliminate or reduce the probability of disaster occurrence, or
reduce the effects of unavoidable disasters.
 measures include building codes
 vulnerability analyses updates.
 Emergency plan in place and practiced
 zoning and land use management
 building use regulations and safety codes; preventive health care; and public
education.
 Hazard mapping to identify the tsunami area
 Education of government officials and public
 Rehearsal of the early warning system
 Arial photographs to illustrate differences between before tsunami and after.

20. conclusion
• Disaster management is very important role in
disaster.it is reduce the effects, vulnerability &
risk by disaster management phases in society
therefore every students want to learn and
people want to know the disaster management.
