摘要
利用P波初动资料,计算2009年11月5日陕西省高陵县M_L 4.8地震震源机制解,并从地震现场考察结果分析烈度分布特征。根据地质构造、历史地震活动背景、震源机制、余震分布、极震区长轴方向,分析本次地震的发震构造,研究认为,该地震发生在泾阳—渭南断裂上。
On November 5th, 2009, an earthquake of ME 4. 8 happened in Gaoling, Shaanxi Prov- ince. This article summarizes the parameters and sequence character of the earthquake, and calculates the focal mechanism solution from initial P-wave data, and also analyzes the seis- mic intensity according to the study results of earthquake zone. We study the seismogenic structure of the earthquake using the combination of geological structure, focal mechanism, after quake distribution, and the meizoseismal area＇s long-axis direction. Finally, we draw a conclusion that this earthquake took place on the Jingyang-Weinan fault zone.
