摘要：震源機制解是研究活動構造及大地應力之基本資料，波形震源機制分析不僅能求取
斷層面解，並可以求取seismic moment，以求取地震規模。在我們的研究區域，包
括一些低地震活動區域，例如：越南紅河斷裂帶。一個地震通常只被一兩個寬頻地
震站所記錄。因此，必須由波形方法進行震源機制分析。本計畫擬以頻率-波数（F-K）
法產生合成地震波，並及基因演算法為基礎建立震源機制分析方法。
Abstract: Waveform focal mechanism determination using genetic algorithm
Focal mechanisms are the fundamental information to investigate active structures as
well as stress analysis. Waveform focal mechanism analysis is not only to obtain fault
plane solution, but also to determine the magnitude of an earthquake. There are many
low seismicity regions in our studies, such as the Red river of Vietnam. An event
generally is recorded by one or two broadband seismic stations. Thus, it is necessary to
use waveform modeling method for focal mechanism determination. In this project, F-K
method will be used for producing synthetic waveform and genetic algorithm will be
applied to find the best parameters of the focal mechanism.
