2. Role of computer in disaster management
Computer-mediated communication in various forms is
already being used in all phases of disaster management-
-preparation, response, recovery, and long-term
mitigation. However, to date wide area computer
networks--particularly the Internet (the supernetwork of
networks)--have been used only to a limited extent in
disaster management and prevention.
individuals who use Internet will become involved not
only in disaster response and mitigation worldwide, but
in the global community and consciousness that is the
Internet.
3. Tecniques of disaster mitigation
Geospatial tecniques ->TheRemote
Sensing, Geographical Information
System, Geodesy, Geophysics, etc may help us in our
endeavor to minimize the destruction caused by
these phenomenon.se includes
This tecniques has two parts
1. Short term response, recovery and rehabilitation
2.Long term response, recovery and rehabilitation.

5. Care taken
1. Landslide Hazard By minimising the losses
Zonation Methodology caused by landslides
Mass Movement Model It is necessary to model
the process of the mass
movement and analyse
the slope stability
Control measures
The other work such as
stablisation of landslide
through soil nailing
technique is in progress.
6. What to do after disaster
General Safety Tips
Wear sturdy shoes when entering a building or walking
through debris after a disaster.
Carry a flashlight when entering dark buildings.
Do not enter a building if the foundation has shifted or
has been weakened.
Do not demolish a building or house without professional
help. Crews from the King County Public Works
Department or licensed contractors can help you.
Buildings must be declared safe before they can be
entered

8. Tsnaumi prevention
The biblical catastrophe that we have
witnessed after the recent earthquake and
the tsunami that followed in Southeast
Asia, could have been prevented to a great
extend if there was in place a functional alert
and communication system that would have
in time alerted the populations of the affected
countries.
10. Earthquake prevention
1. Scientists are continuously thinking of ways to try
and reduce earthquake power. Some are trying to
lessen the friction between colliding plates
Special instruments are now in existence to give
warnings in California, Japan, and New Zealand
Architects are also designing earthquake-proof
buildings, constructing on rock instead of gravel, or
on soft sand or clay
Researchers are always trying to reduce the impact of
earthquakes
12. Prevention of volcano
Currently, it is impossible to prevent a volcanic
eruption, but it is possible to keep damage to a
minimum. In 1973, citizens of Iceland poured cold
water onto flowing lava to slow it down, an act that
helped save the fishing port of Heimay. In Sicily, on
Mount Etna, engineers have blasted holes in the
hard crust covering a lava flow using explosives. The
lava then turns to flow out through the holes instead
of swallowing villages in its original path.
