A general method for multi–hazard intensity assessment for cultural resources: Implementation in the region of Eastern Macedonia and Thrace, Greece

Abstract

The protection of cultural resources from natural and human–induced hazards has been an area of intense scientific interest over time. The literature highlights that, despite the intensive research efforts to date, there is a lack of a commonly accepted hazard assessment framework that supports decision–making to limit their negative effects and contribute to the protection of cultural heritage. In this paper a general method for assessing the intensity of multiple hazards on cultural resources is developed and applied. The proposed method utilizes a) the capabilities of Geographic Information Systems (GIS), b) open geospatial hazard data and c) an original 7–step integrated method developed in this research. Key features of the proposed method are its ability to consider and synthesize intensities of both quantitative hazards such as earthquake, flood and hazards expressed on a qualitative scale, such as wildfire and landslide. The proposed method is applied to assess the exposure of 918 cultural resources of the Region of Eastern Macedonia and Thrace, Greece, to earthquake, flood, landslide, sea level rise, wildfire, soil erosion and industrial–technological accident and develop an aggregate multi–hazard intensity index (mhii) for each of the cultural resources in this region. The proposed method can be applied to hazard intensity assessment for resources other than cultural, such as the human capital of a region, infrastructure, environment, and economic facilities. This provides researchers, scientists, and managers of cultural sites with a tool to set priorities for the design of appropriate mitigation strategies to reduce the negative impacts of hazards.
