| 1 | Spatiotemporal characteristics of the energy radiation sources of the three great earthquakes near Sumatra Island in September 2007显示文摘Three strong earthquakes with magnitudes of MW 8.4, MW 7.9 and MW 7.0 occurred in the sea west of Sumatra Island on September 12 and 13, 2007. We relocated the epicenters and focal depths of the three events by means of the reversal-time imaging technique using broadband digital seismic data from worldwide stations ranging from 30° to 90°, imaged the spatiotemporal variation of the energy radiation sources by means of the nonplane wave array technique using the broadband digital seismic data from a generalized array made up of 33 stations of the Capital Region Digital Seismograph Net-work (CRDSN), and obtained the rupture duration times, extents and rupture velocities. Also, we dis-cussed the correlations between the locations of the energy radiation sources of the three events. | XU LiSheng DUHaiLin ZHANG HongXia ZHANG Yong LI ChunLai ZHAO Hua | 2008 | Chinese Science Bulletin2008，53，15： | 0 |
