2. Science helps us predrict hazards
Why is it important to predict hazards?
● Predict the risk of death and injury.
● Reduce damage to property and land.
● To protect agriculture, e.g. move cattle to higher lands during a
flood.
● To give warn citizens in order to give them time to evacuate.
● Cancel all non-essential travels e.g. flights and shipping.
● To prepare the emergency services.
3. Knowing hazard risk can help
people make decisions
What should we do before we make a decision?
● Before me make a decision, first we need to estimate the
risks.
● Determining the probability of an event it's the most difficult
part, but when we determine the consequences of the
particular event is fairly straightforward calculate the
estimated property damage and loss of lifes.
4. Consequences of hazards can be
minimized
We can reduce the consequences of hazards by:
● Improving procedures, this will reduce the landslide
damages.
● Adequating grading and soil analysis ordinances can
reduce landslide losses
● Using the seismic-resistance structures in buildings.
● Constructing on landfills or soft mountain slopes, like
this, the buildings wont suffer such damages like in
solid ground.
5. Humans can turn disastrous events
into catastrophes
● People are living in large numbers in hazardous
places. In addition people alter the landscape in ways
that can contribute to disasters for example the CO2
emissions from the cars and the factories.
