中文摘要:
在 Qingchuan 差错地区的套住的波浪在 Wenchuan Ms8.0 地震的折断的地区的东北结束附近在 Muyu 被观察。结果在差错的不同方面上在外壳的物理性质显示大约 200 m 和大差别的差错地区宽度。外壳的变化的推断的地点与表面上的地形边界一致。
英文摘要:
Trapped waves in the Qingchuan fault zone were observed at Muyu near the northeastern end of the fractured zone of the Wenchuan Ms8. 0 earthquake. The results indicate a fault-zone width of about 200 m and a great difference in physical property of the crust on different sides of the fault. The inferred location of crustal changes is consistent with land-form boundary on the surface
