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 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。

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。

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。

Then the compression itself is accompanied by very powerful shocks such as those that seismographs recorded, therefore, approximately 25% of moon quakes as a result of cooling of the lunar subsurface.

然后，这种压缩本身就伴随着非常强烈的震动，比如地震仪记录的那些震动，因此，大约25%的月球地震是由于月球地下表面冷却造成的。
