چکیده:

Resilience against earthquakes is a broad concept that requires a multi-disciplinary response.This paper offers a working definition of resilience and associated concepts, including vulnerability to earthquakes, coping, capacity and redundancy. It concludes that resilience must be set in motion and maintained by a collective effort that involves all stakeholders and people who are at risk in areas of high seismicity. Resilience is one of the fundamental components of disaster risk reduction (DRR), an overall strategy for adapting to and mitigating the impact of extreme events on people and society. The paper offers a modest contribution to the creation of a methodology for resilience against earthquakes. This includes ten suggestions for action, as follows. (1) Tell people what to do in an earthquake. Research is needed on the best forms of self protective behaviour during seismic emergencies. This needs one to understand the characteristic forms of building failure and how they affect building occupants. It also requires knowledge of how people react to earthquakes and what opportunities there are for self-protective behaviour. (2) Develop urban search and rescue capacity on site. This need not be expensive or particularly challenging. It requires stockpiling of basic rescue equipment at strategic points in urban areas and training programmes for local residents. (3) Reduce non-structural as well as structural hazards. A significant proportion of earthquake injuries arises from damage to the non-structural elements of the built environment. Anchoring and securing these, and designing them to resist earthquake displacement, can save lives and reduce the incidence of serious injuries. (4) Plan flexibly. Emergency planning should be a process and not an end. It must be adapted continually to changes in knowledge of hazards and in society and its vulnerability. (5) Create networks. These can improve the exchange of knowledge, information and training. Networks are needed at all scales, from the local to the international, and from professionals to local residents threatened by earthquakes. (6) Encourage governance. This requires involvement of many different kinds of stakeholder in the processes of earthquake disaster risk reduction. (7) Make good practice proliferate and adapt it to local circumstances. (8) Ensure that programmes of DRR are sustainable in the long term. In order to work they must have a constant revenue stream and also the full support of beneficiaries. (9) Before the next major seismic event occurs create a strategy for recovering from it. Consider how the recovery will be planned and guided, and what needs will be generated by the event. (10) Create a culture of resilience against earthquakes, in which the problem is widely understood and taken seriously by people who are at risk or are in positions of authority. This also involves sharing knowledge about earthquakes and sharing the risk to society.
