A presentation on natural hazards was given by group members Ahsan Jamal, Ramakant Pandey, Shripad Dongare, Sahil Nikam, and Shahrukh Shaikh. The presentation introduced natural disasters and defined them as major adverse events resulting from natural Earth processes like floods, volcanic eruptions, and earthquakes. Natural disasters were classified into meteorological, topographical, and environmental categories. The top 10 natural disasters were identified as cyclones, earthquakes, tornadoes, volcanic eruptions, tsunamis, floods, wildlife, drought, avalanches, and landslides. Causes of natural disasters included movements of the Earth, weather events, and secondary disasters like floods and

3. Introduction to natural disasters.
• A natural disaster is a major adverse event resulting from
natural processes of the Earth; examples include floods,
volcanic eruptions, earthquakes, tsunamis, and other geologic
processes.
• A natural disaster can cause loss of life or property damage,
and typically leaves some economic damage in its wake, the
severity of which depends on the affected population's
resilience, or ability to recover.

4. Contd….
A disaster is a natural or man-made event
that negatively affects life, property,
livelihood or induastry often resulting in
permanent changes to human societies,
ecosystems and environment.

7. Causes of natural disaster.
Natural disasters fall into three broad groups:
1. Those caused by movements of the Earth. These occur with
the minimum amount of warning and include earthquakes,
volcanic eruptions and tsunamis. They are difficult to predict
and impossible to stop.
2. Weather related disasters. These will include hurricanes,
tornadoes, extreme heat and extreme cold weather. There will
usually be some degree of advanced warning, but since weather
is unpredictable, nothing can be done to stop these disasters
from developing once the weather system develops.

3. Floods, mudslides, landslides and
famine. These are usually the consequence of
extreme weather events, or are supplementary
to other natural disasters. Often they are the
result of extreme and unforeseen conditions.

9. Natural Disaster effects.
According to a 2014 reportby the UnitedNations, since 1994, 4.4
billion people have been affected by disasters, which claimed 1.3 million
lives and cost US$2 trillion in economic losses.
Low- and lower-middle-income countries are disproportionately
affected by natural disasters. In the same 20-year period, 33 percent of
countries that experienced disasters were low- to lower-middle income,
but 81 percent of people who died in disasters lived in these countries.
8 out of 10 of the world’s cities most at risk to natural disasters are in
the Philippines.
Natural disasters affect the number of people living below the poverty
line, increasing their numbers by more than 50 percent in some cases.
The problem is getting worse; up to 325 million extremely poor people
are expected to live in the 49 most hazard-prone countries by 2030.

10. Areas affected by natural disaster:

12. Preventing measures for natural
disaster.
4 measures ways to prevent natural disasters from
becoming human tragedies:
1. Early warning systems for famines.
2. Wonder hunger-products to address malnutrition
3. Giving money directly to the poor so they can help
themselves.
4. Mobile technology that informs and empowers
citizens.
