Natural Hazards are comprised of 2
1. A natural disaster (a physical event
e.g. volcanic eruption, earthquake,
2. Human activity – for example coastal
settlement of populations
A natural disaster is
an event that has an
effect on people
resulting from the
natural processes in
Vulnerability is the susceptibility to physical or
emotional injury or attack
Human vulnerability leads to financial, structural, and
A natural hazard will therefore never result in a natural
disaster in areas without vulnerability, e.g. strong
earthquakes in uninhabited areas.
The risk of natural disasters is increasing as a result of
population growth, urbanization, and alteration of the
Events that societies label as natural ''disasters"
may also have beneficial ecological
However, these benefits tend to only manifest
themselves months or years after an extreme
event (e.g., rejuvenation of a coniferous forest
months and/or years after fires), or are often
not readily apparent (e.g., recharging of
groundwater stocks after a flood).
Create your own powerpoint presentation about
a natural hazard.
You will be assigned a particular hazard.
You will work in groups of 4.
You will have 2 periods to complete this
Should be 6-8 slides
This will not be presented to the class, instead
put it into Miss Wilkins pass in folder when you
1. Describe what the natural hazard actually is.
2. Describe the causes
3. Describe the effects on humans
4. Describe the positive/negative effects on
5. Provide ways that we can reduce the effects
The project will be marked out of 10.
2 points will be awarded for including each of
the 5 criteria.
