Some of them were over 5 kilometers below the water surface.

其中一地震仪被放在水面以下超过5公里处。

The crash sends energy through the ocean floor where it can be measured by seismographs.

撞击产生的能量穿过海底，在海底可以用地震仪测量。

But Bromirski said large waves create enough energy to be measured by seismographs, also.

但布罗米尔斯基说，巨浪也能产生足够的能量供地震仪测量。

The snag lies with the seismometer, capable of measuring group movement as small as the diameter of an atom.

问题出现在了地震仪，它可以检测至原子级别的地面运动。

Those measurements permitted Bromirski to judge the strength and size of waves over a period of 90 years.

地震仪在海底测量的数据使布罗米尔斯基能够判断90年来海浪的强度和大。

That is a part of Mars where some kinds of seismic waves cannot travel directly to InSight's seismometer.

这是火的一部分，在那里，型的地震波无法直接到达“洞察号”的地震仪。

Dark fiber covers much of the country, and stretches across the ocean basins-which are hard to study using traditional seismometers.

暗光纤覆盖了全美大部分地区，并延伸至整个海洋盆地地区，而海洋盆地很难用传统的地震仪来研究。

A woman was introducing a self-adjusting seismograph to some people.

一位妇女正向人们介绍一种自动调节的地震仪。

It's got an arm… It can listen with its seismometer.

它有一只手臂… … 它可以用它的地震仪听。

He was like, he was like one of those machines that register earthquakes 10,000 miles away.

他就像一台地震仪，能探测到万里之外的地震。

Geologists have long used seismometers to track and map these tiny shifts in the earth's crust.

地质学家早已使用地震仪来追踪、绘制地壳中的这微变化。

Scientists have been trying to replicate this seismoscope for centuries, even as recently as 2005, all unsuccessfully.

几个世纪以来， 科学家们一直在尝试复制这种地震仪，甚至最近在 2005 年， 都没有成功。

29 small, underwater observatories, equipped with pressure sensors, seismometers and accelerometers, are installed directly on the fault-line off the coast of Osaka.

29个型水下观测站，装备有压力传感器、地震仪和加度计，直接安装在大阪海岸的断层线上。

In an earthquake, some vibrations bounce off the seafloor and turn into sound waves that get picked up by seismometers and underwater microphones.

在地震中，一振动从海底反射回来，转化为声波，被地震仪和水下麦克风接收。

That sounds a silly suggestion, but that was precisely the idea adopted in some of the early instruments (seismometers) for recording earthquake waves.

这听起来似乎是一种愚蠢的想法，但是早期记录地震波的仪器（地震仪）正是采用了这种思路。

NASA's InSight mission, which landed on the Red Planet about a year ago, placed a seismometer on the planet's surface to listen for quakes.

一年前，美国国家航空航天局（NASA）的“洞察”号探测器在火登陆，并在火表面放置了地震仪来监测地震。

Don't be scared, I was just kidding The instrument used by Scientists to measure the intensity of Earthquake is known as a Seismograph!

不要害怕，我只是在开玩笑 科学家用来测量地震强度的仪器被称为地震仪！

NASA's InSight mission, which landed on the Red Planet about a year ago, placed a seismometer on the planet's surface to listen for quakes.

大约一年前降落在这颗红色球上的 NASA 洞察号任务在火表面放置了一个地震仪以侦听地震。

To avoid this, NASA scientists plan to place 10 more seismographs on the lunar surface in order to find the calmest areas where tremors are least likely.

为了避免这种情况，美国宇航局的科学家计划在月球表面再放置10个地震仪，以便找到最平静的地区，那里最不可能发生地震。

Scientists use a range of tools, from seismometers to satellite imagery, to track signs of unrest such as seismic activity, ground deformation, and gas emissions.

科学家使用从地震仪到卫图像等一系列工具来追踪地震活动、地面变形和气体排放等动乱迹象。
