| Summary: | 碩士 === 國立宜蘭大學 === 建築與永續規劃研究所碩士班 === 100 === When an earthquake occurs, it may induce ground shaking and soil liquefaction. Also, it may cause damage to buildings, bridges and infrastructures, and may result in casualty and economic losses in a wide area. Thus, preceding to the planning of emergency shelters, we need to perform seismic hazard analysis and seismic losses assessment.
Taiwan has advanced to an advanced age society because of the rapid increase of older persons. How to help older persons to take refuge in a seismic event is a great concern. In this study, using Yilan City as an example, we discuss issues related to seismic hazard analysis, seismic losses assessment, evacuation of older persons, and planning of emergency shelters.
In this study, according to seismic sources around the Yilan area, we select a magnitude 7.0 earthquake occurring in Okinawa trough seismic zone as the simulation earthquake. Then we estimate ground shaking and soil liquefaction caused by the selected simulation earthquake and make microzonation maps for ground shaking and soil liquefaction in the study area. In addition, we use the software “Taiwan Earthquake Loss Estimation System, TELES” to evaluate seismic losses such as buildings damage, casualty, and refuge population.
We delineate six disaster prevention territories based on the installation of united neighborhoods in Yilan City. Then we investigate all places that may be used as emergency shelters, including schools, parks, and stadiums, and compute corresponding supply area. We also compute the area demanding by the refuge population based on the TELES results. From the comparison of supply and demand areas, we conclude that Yilan City has enough spaces for emergency shelters.
In this study, we collect data on older persons including those living alone and nursing homes in Yilan City. In addition, with reference to pertinent disaster prevention plans and behavior of older persons, we formulate an operation procedure for the evacuation and refuge of older persons in Yilan City following an earthquake event. Furthermore, because the living habits of older persons are different from those of the general public, we suggest that a special area in emergency shelters should be set up for older persons. We also suggest that barrier-free facilities and medical care service should be provided for older persons, so that older persons will have a better refuge life. Finally, based on the findings of this study, we draw four conclusions and two ideas for further research.
