If an ocean floor tectonic plate meets the edge of a continent and they push against each other, the heavier one sinks down and goes under the other one.
如果一个海底构造板块与大陆边缘接触并相互挤压，较重的板块下沉到另一个的下面。
Instead, they are other volcano types, like strata volcanoes, for example, which are a result of the tectonic plate movement.
相反，它们是其他类型的火山，比如地层火山，是板块运动的结果。
Wilson suggested that the long chain of volcanoes stretching northwest from Hawaii is simply the surface expression of a long-lived volcanic source located beneath the tectonic plate in the mantle.
威尔逊认为，夏威夷向西北延伸的火山长链只是一个长期存于板块下、地幔中的火山源在板块表面的表现。
That was the same day as the 9.0-magnitude quake and tsunami hit Japan; however, Japan is on a different tectonic plate.
同天，9.0级的地震及海啸在日本发生。但这两个地方并不处在同一个地壳构造板块上。
Along the coast of Pakistan, the tectonic plate underlying the Arabian Sea is diving beneath the Eurasian continent.
沿着巴基斯坦的海岸线，阿拉伯海板块下潜嵌入了欧亚大陆板块。
All it takes is for that wallop to act upon a weak point, crushing it, which then allows a tectonic plate to move... maybe an inch.
它所要做的全部就是让这一冲击力作用于一个薄弱点，挤垮它，然后使得一个构造板块移动…可能是一英寸。
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。
The quake happened along a seam in the planet's surface where the Pacific Ocean floor is diving beneath the tectonic plate carrying northern Japan (see 'Collision zone').
这次地震是沿着地球表面的一条缝隙发生的。在这条缝隙处，太平洋板块正俯冲入另一地壳板块下部，而这块地壳板块正承载着日本的北部地区（见”碰撞带“）。
The major earthquakes and active volcanoes occurring there are caused by the westward movement of the Pacific tectonic plate and other plates leading to subduction under Asia.
由于太平洋构造板块及其他几个板块的向西移动，导致其向亚洲板块之下俯冲，从而会在这一带引发大地震和火山活动。
Well, that's just like what's happening with the Hawaiian Islands, but instead of a sheet of paper, you've got a tectonic plate, and it's moving over this plume of intensely hot magma.
这和夏威夷群岛正在发生的事情是一样的，只不过那是一个地壳板块，而不是一张纸，它正移动到这种炙热的岩浆火焰上方。
In subduction zones, where older and colder oceanic crust descends beneath another tectonic plate, Deep focus earthquakes may occur at much greater depths (up to seven hundred kilometers).
在隐没带，当更老的和更冷的海洋地壳下降到另一个构造板块下面时，深震源地震可能会发生在非常深的深度(达到700公里)。
In subduction zones, where older and colder oceanic crust descends beneath another tectonic plate, Deep focus earthquakes may occur at much greater depths (up to seven hundred kilometers).
