Description

Method and system for supporting field operations using by risk level assessment of earthquake disaster area The present invention relates to a method and system for providing field support through earthquake disaster regional risk assessment, which evaluates regional risk levels caused by earthquake disasters and provides field support based thereon. Regarding the aggregation of disaster data for regional disaster assessment, Korea has limited its efforts to compiling annual disaster reports using programs such as Microsoft Excel by collecting damage data reported by each region when a disaster occurs, summing up the number of facility damages, land loss, and casualties by disaster type, and converting and aggregating these results into monetary value. Furthermore, comprehensive data on a nationwide scale merely presented the damages for a specific disaster during a given period as a comprehensive amount by aggregating each item based on regional annual reports. Therefore, based on the aforementioned comprehensive data, it was impossible to obtain detailed information regarding the disaster, conduct an impact assessment reflecting regional characteristics, determine the correlation between the disaster and the damage, or evaluate the disaster damage mitigation capabilities of specific regions. Furthermore, Korea lacks a comprehensive evaluation system and objective risk assessment indicators for assessing the safety management capabilities of local governments, making it difficult to implement disaster prevention projects and establish response plans that consider regional characteristics. Additionally, the system for inducing efforts to secure a safety foundation—such as the level of interest in disaster prevention by local government heads, budget allocation rates, facility investments, and personnel allocation performance—is inadequate. Furthermore, it was difficult to ensure continuous objectivity in evaluating regional disasters using the disaster-related information obtained through the aforementioned work. First, since the evaluation area is determined first and data is collected, there was an inconvenience in managing past history where it became almost impossible to utilize the accumulated data if the administrative boundaries of the relevant region changed in the future. Additionally, while the causes of natural, man-made, and social disasters depend on countless factors, it was difficult to identify the causes due to the lack of systems for securing, storing, standardizing, and managing basic data. Moreover, disaster damage causes indirect damage to the regional economy by affecting not only facilities and human lives but also regional productivity and residential stability; however, there is a problem in that there is no method to calculate such indirect damage.
