• Perspectives on Disasters Most people would look at disasters in the same perspective. As humans, the first thing we notice in the aftermath of a disaster is its effects on fellow humans. However, to evaluate the overall results of a disaster, disaster experts examine them from different points of view. The physical perspective includes the visible or tangible materials, whether natural or man-made, which have been affected by a disaster. The altered or removed structures may change the landscape, zoning, and accessibility of an area. For example, cracks or fissures on main roads may require a detour or a new access road. Hence, changes in the frequency of movement of people and vehicles in the area may eventually affect zoning, or the value and use of the properties within the vicinity. Fig. 1.5. The Department of Social Welfare and Development (DSWD) conducts stress debriefing sessions to help disaster victims cope with the trauma of losing their properties and/or loved ones.
