2. Role of computer in disaster management Computer-mediated communication in various forms isalready 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. 4. The uncertain monsoon winds make the region highly prone to natural disasters. The region being the most populous in the world further add to the damage caused by the natural disasters.Natural disaster mitigation 5. Care taken 1. Landslide Hazard By minimising the lossesZonation Methodology Mass Movement Modelcaused by landslides It is necessary to model the process of the mass movement and analyse the slope stability The other work such as stablisation of landslide through soil nailing technique is in progress. Control measures 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 7. Engineer role in disaster Pre-disasterPost -Disaster . Designing Classifying damagedearthquake resistant structures. Seismic evaluation of building and its components.structures Proposing choice of repair methods and strengthening techniques 8. Tsnaumi prevention The biblical catastrophe that we havewitnessed 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. 9. Arrival of Tsunami In worldThis picture shows the earthquake epicenter 10. Earthquake prevention 1. Scientists are continuously thinking of ways to tryand 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 11. The areas areMorrocco Southern Itxly Earth quake region 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. 13. This is caused after earthquakeVolcano eruption
