Feasibility and Problems of Earthquake Disaster Reduction Measures Based on Active Fault Data

Abstract

Active fault data have been more widely and closely investigated and extensive data have also been collected. However, there are only a few examples related to land use planning for disaster reduction measures based on active fault data. The purpose of this study is (1) to categorize the disaster reduction measures, and (2) to examine problems and important factors for promoting disaster reduction measures based on a questionnaire survey. The cases of the measures that are able to be distinguished included building restriction, nonconstruction restriction, and risk communication. The questionnaire survey was conducted with the residents of Yokosuka city. The results of analyses showed that disaster reduction measures based on active fault data tended to be approximately accepted. Other results indicated that as the public's understanding related to earthquake risk and risk mitigation measures increases, the awareness of risk reduction measures based on active fault data is promoted, and the objectives of disaster reduction measures would be realized.

Research on Technology and Application of Buried Faults Identification in Urban Underground Space

“…At the same time, the losses of urban geological disasters account for about 90% of the global earthquake disaster losses [12]. Therefore, we should strengthen the research on the detection and identification of urban underground faults [13][14][15][16], effectively grasp the blind faults, activity attributes and distribution characteristics of urban underground faults, and evaluate the potential geological safety risks in serving urban planning and urban construction [10,17], so as to avoid the destructive effect of earthquake disasters caused by urban underground faults as much as possible [18][19][20][21][22][23], and further improve the safety of future urban construction areas [24][25][26][27][28][29][30][31], building types and building layout.…”
