There are many kinds of disasters taking place in the globe such as coastal erosion, tidal waves, floods, soil erosion, increased storm intensity, species migration, fire and explosions which can be damaged to human lives as well as cultural heritage. A significant number of human lives and cultural heritage destroy due to unavailability of effective early warning dissemination system. Therefore, disaster prone countries should take preventive measures to minimize the damages created by natural disasters. Human actions are causing greater change in climate and that will have a significant adverse impact on the cultural heritage. Many historic cultural sites are likely at risk from direct impact of human actions. It is prudent to take sound action to protect world heritage from natural or man–made causes, as it destroys both cultural property and the people. It is our collective responsibility to protect our heritage for present and future generations. This paper describes the natural and man-made disasters and mitigation measures taken by the Sri Lankan government to build strong community.
