| 英文摘要 | Combining the newly established Longmenshan Seismic Gap Array (LmsSGA) with the permanent stations from Sichuan Earthquake Administration, we carry out double-difference location for 23479 events from November 21st, 2016 to October 28th, 2017 in Longmenshan Fault Zone and obtain 6111 relocated events including Wenchuan aftershocks and Lushan aftershocks. Comparing with the early aftershocks of Wenchuan event, we find that the aftershocks are still active after 10 years of Wenchuan earthquake. The Wenchuan aftershocks mainly distribute between 10 to 25 km in depth, and the focal depths in the southwestern section are much deeper compared with the depths in the northeastern section. In addition, compared with the early aftershocks of Wenchuan earthquake, the distribution of the latest aftershocks is much deeper. The aftershocks migrate toward the deeper depth in the most recent years. However, the aftershocks of Lushan earthquake are relatively weak. Moreover, the depths are mainly located between 10 to 15 km, which are much shallower than the earlier aftershocks. The distribution of the latest aftershocks in Longmenshan Fault Zone shows that the aftershocks migrate in space with time. Considering that the elapse time has been 5 similar to 10 years after the two mainshocks respectively, we suggest that the aftershock migration may be triggered by quasi-static mechanism, such as fluid diffusion. |
