1·This huge jolt happened as the Nazca plate moved down and landward below the South American plate.

这次巨大的摇晃发生在纳斯卡板块下移，向南美板块下的近陆移动。

2·The two plates are converging at a rate of 80 mm per r, with the Nazca plate moving down and landward below the South American plate.

两个板块每年以80毫米的速度靠拢，纳斯卡板块沿着朝向陆地并偏下的方向在南美板块下方移动。

3·Just off its coast is the Nazca plate, which rests below the south-eastern Pacific Ocean and slides beneath the South American tectonic plate by some 9 centimetres a year.

智利的海岸线外是纳斯卡板块，它位于太平洋的东南方下面，以每年9厘米的距离向南美板块下俯冲。

4·By measuring the slow rising and falling of the ground as the inexorable collision of the Nazca plate squeezed the coast, they could calculate how fast strain was actually building.

通过测量因纳斯卡板块挤压海岸发生碰撞造成的地面的缓慢上升与下降，他们能够估算压力的实际聚集速度。

5·The geology of this part of the Andes is a result of the eastward subduction of the Nazca tectonic plate underneath South America.

该区域安第斯山脉的地质结构是纳斯卡板块向东俯冲，下穿垫在南美版块之下。

6·The plate structure where s America meets the Caribbean and the Nazca and Cocos Plates is complex.

南美板块，加勒比板块和科科斯板块(Cocos Plates)交接处的板块结构很复杂。
