摘要 2009年4月6日1点32分42秒协调世界时(UTC),在意大利中部地区发生了MW6.4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132°、倾角53°、滑动角-103°的节面是地震发生的断层面. An Mw6.4 earthquake occurred in L'Aquila, central Italy at 1:32.42 UTC, April 6, 2009. We quickly 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 132°, dip 53°, rake -103° is the seismogenic fault.
