In order to consider risk reduction measures, we should first have an idea of likely risks from landslides and snow avalanches. These are as follows:
i) Geographical risks:
- Spread and deposition of debris
- Blocking of Streams
ii) Engineering risks:
- Buildings
- Roads
- Bridges
- Communications
iii) Medical risks:
- Death
- Injury
- Shock
ADVERTISEMENTS:
iv) Socio-economic risks:
- Loss of family
- Loss of homes
- Loss of crops
- Loss of employment
The above-mentioned risks can be reduced by adopting risk reduction measures which can be divided in two categories, viz, (a) Risk Control Measures and (b) Risk Assistance Measures;
