沿安第斯山的贝尼奥夫带构造显示出,在山脉不同地段上,贝尼奥夫带的形状、斜度和深度有较大的差异。在安第斯山的北端和南端,贝尼奥夫带的倾角和深度明显地比中部的小和浅。安第斯山唯一的深震(大于500公里)部分与安第斯中部的较大倾斜地震带一致,此段还存在一深而发育良好的海沟(卡内基海脊和胡安费尔南德之间;南纬5°—33°,图2)。 The structure of the Benioff belt along the Andes shows that there is a large difference in the shape, slope and depth of the Benioff belt in different sections of the mountain range. At the northern and southern Andes, the dip and depth of the Benioff belt are significantly smaller and shallower than the central part. The only part of the Andean deep earthquakes (more than 500 km) is consistent with the larger inclined seismic zone in the central Andes, where a deep and well-developed trench (between the Carnegie Ridge and Juan Fernand; South latitude 5 ° -33 °, Figure 2).
