The destruction of old ocean floor happens in 'subduction zones.'

旧海底的破坏发生在“”。

And I love traveling to subduction zones all over the world.

我喜欢去世界各地的区。

We used to think that tsunamis only strike in areas where you have subduction zones.

我们过去认为海啸只会发生在有的地区。

And since wet rock is easier to melt, subduction bringing water down into the Earth helps the crust melt easily.

由于潮湿的岩石更容易融化，水进入地球有助于地壳轻松融化。

Ide is now doing a similar analysis on earthquakes that all happened in the same geologic setting, like subduction zones.

井出哲现在正在对所有同一地质环境下发生的地震进行相似性分析，比如说消减。

Why don't we see it distributed throughout the entire subduction zone?

为什么我们没有看到它分布在整个？

However, we didn't actually discover the Cascadia subduction zone until 1988.

然而，直到 1988 年，我们才真正发现卡斯卡迪亚。

But subduction zone earthquakes actually give us a warning because the vibrations they cause travel at different speeds.

但地震给了我们一个警告，因为它们引起的振动以不同的速度传播。

On Earth, this recycling process usually happens at subduction zones, where the oceanic crust slides beneath the continental crust, warming as it goes down.

在地球，这种循环过程通常发生在，即海洋地壳滑落到大陆地壳之下，并在向下移动的过程中变暖。

The collision caused the edge of the Nazca plate to get pushed under the South American plate, in a process called subduction.

碰撞导致纳斯卡板块的边缘被推到南美板块下方，这个过程称为。

Unlike other subduction zones and this is the crease right here, this plate would be diving below this plate here, which is just sitting here.

不像是其他, 汇聚点就在这里, 这个板块将潜于位于这里的该板块之下。

And the subduction continued through the extinction of Kronosaurus, and later, that of all of the plesiosaurs at the end of the Cretaceous.

一直持续到克朗龙灭绝，然后是白垩纪末期所有蛇颈龙的灭绝。

So in this way, subduction zones are like portals into the deep earth, where materials are exchanged between the surface and the subsurface world.

所以这样一来， 就像进入地球深处的门户，地表和地下世界之间进行物质交换。

A lot of subduction zone earthquakes are 200 miles deep, and there's a lot of padding between the shaking part and the earth surface where we live.

大多的地震有200英里深, 而且地震和我们生活的地球表面之间有很多填充部分。

And of course I said yes, because, I mean, Costa Rica is beautiful, but also because it sits on top of one of these subduction zones.

当然，我说是，因为，我的意思是， 哥斯达黎加很美，还因为它位于这些之一的顶部。

The site of this destruction is another kind of plate boundary: a subduction zone. There one plate dives under the edge of another and is reincorporated into the mantle.

一块潜没的区域。在这里，一块板块潜没到另一板块的边缘之下并结合入地幔之中。

Deep Ocean Trenches: The Subduction Zones In contrast to mid--ocean ridges, deep ocean trenches form at convergent plate boundaries, where one plate descends, or 'subducts, ' beneath another.

深海海沟： 与洋中脊相反，深海海沟形成于会聚板块边界处，其中一个板块下降或“”到另一个板块下方。

Most cities in the Northwest US are far back from the coast and the subduction zone, which means they'll be given a warning before the major shaking starts.

美国西北部的大多数城市都远离海岸和，这意味着它们会在大地震开始前收到警告。

The eruption was driven by subduction, a process whereby one of Earth's tectonic plates (in this case the Pacific one) sinks beneath the edge of another (in this instance the Indo-Australian one).

这次火山喷发是由驱动的，即地球的一个板块（本例中为太平洋板块）下沉到另一个板块（本例中为印度-澳大利亚板块）边缘之下的过程。

They all have something in common in addition to killing tens or hundreds of thousands of people, they are all subduction zone quakes, created when one tectonic plate is forced under another.

除了造成数万人或数十万人死亡之外， 它们都有一些共同点，它们都是地震， 是在一个构造板块被压入另一个构造板块时产生的。
