摘要 2009年8月3日17点59分56秒协调世界时(UTC),在加利福利亚湾发生了MW6.9地震.作者利用矩张量快速反演技术,通过反演全球台网的宽频带P波波形得到了这次地震的矩张量解,并判断走向127°、倾角81°、滑动角179°的节面是地震发生的断层面. An MW6.9 earthquake occurred in Gulf of California at 17:59:56 UTC, August 3, 2009. We obtained the moment tensor solution of the earthquake by inverting the P waveforms of broadband recordings from the GSN stations using the quick technique of moment tensor inversion, and further inferred that the nodal plane of strike 127°, dip 81°, rake 179° be the seismogenic fault.
