摘要

九二一集集大地震有446筆觀測站紀錄的資料，龐大的數據資料造成分析上一大的問題，本論文利用計算機圖學的技術，配合視覺化知識的基礎，去實做九二一集集地震視覺化系統，對於大量數值的紀錄，運用視覺化的呈現，幫助科學家去了解地震發生的過程。透過視覺化過程分析，可以清楚觀察到地震發生時能量釋放情形，這對於未來防災研究上都提供極為重要的資訊。結合了OpenGL與GMT(generic mapping tool)工具去做出一系列能量地圖，去分析九二一集集地震發生時，能量在臺灣各區傳遞的情形，從中也發現到能量在不同地質條件產生不同的變化。運用視覺化技術將大規模數值轉為清晰易懂的圖形、甚至互動的輸出，期能在分析研究減短時間，也給科學家、地震學者提供額外資訊，對於未來災害預防上提供參考依據。

Four hundred forty-six observation recorded data of Chi-Chi earthquake were obtained. Because of the huge amount of seismic data, it becomes difficult to analysis. This study uses computer graphics techniques to implement the Chi-Chi earthquake visualization system. The goal is to help scientist better understand. Through the visual analysis, we clearly observe the energy release. It provides important information for disaster prevention. We used GMT to generate a series of energy map. We found that the energy distribution was different under different geology condition. Visual technique transforms values into graphs. It reduces time on analysis research, it also provide helpful information for scientists and seismologists. It offers useful information for disaster prevention.
