OVER VIEW
The term Disaster management can be described as “The range of activities designed to maintain control over disaster and emergency situations and to provide a framework for helping at-risk persons to avoid or recover from the impact of the disaster.”[1]
In the last few years, the occurrences of natural disasters have been continuing changing our lives, damaging property and life styles in many different ways.
TYPES OF NATURAL DISASTER
Earthquake
Landslide
Floods
Cloudburst etc.
However, if we are adequately prepared, its possible to severely reduce the impact of a disaster.
MOTIVATION
To minimize the effect of natural disaster before or after the disaster occur.
As we know we cannot avoid the natural disaster but we can reduce its effects
Disaster management is defined as encompassing mitigation, preparedness, response, and recovery efforts undertaken to reduce the impact of disasters, [2]
Immediately after the occurrence of a disaster, the first responders go to the affected region to rescue people and solve eventual problems. These areas offer many dangers to the rescue team. Furthermore, the communication network infrastructure has usually been destroyed.
For these reasons, it is important to create a structure to sense environmental data to detect hazards.
This structure needs to be independent, easy deployed and adapted to different situations
Disaster relief operations
Pre-disaster detection via sensor network in the vulnerable area.
To make a system that collect date related to the event .
Analyze the data through decision making algorithm and that can alert the people.
Post-disaster mechanism.
Drop sensor nodes from an aircraft over a disaster effected area
These node form a network , and each node collect data from specified region.
Via network data flow to the base station.
Each node measures temperature, pressure, humidity, motion of object(eg; rock/soil slide)
Derive a “temperature map” “humidity chart” “pressure flow” “motion graph” etc.
