And now that they've identified those signals they'll be able to look back at decades of data and use these newly discovered seismic fingerprints to better identify small earthquakes like this in the past.

既然他们已经鉴别出那些信号，他们将有能力回顾几十年的数据，并利用这些新发现的地震指纹更好地鉴定以前发生的这类小型地震。

But the greatest moment of all was when the biggest hump broke like a small earthquake and out came the sloping back, the large, wise head, and the four baggy-trousered legs of an elephant.

It depends on where you live exactly, but that's about average, although there are many small earthquakes that most people don't feel that are taking place all the time, at least that's what I've read.

这取决于你住在哪里， 但这大约是平均水平，虽然有许多大多数人感觉不到的小地震一直在发生， 至少我读到的是这样。

The researchers studied the slight deformations in the cable and were able to sense a small earthquake, pinpoint unmapped faults in the seafloor and observe movements in the water column—all of which might be of interest to oceanographers.

研究人员研究了电缆的轻微变形，并能够感知到小地震、查明海底未测绘的断层并观察水柱的运动——所有这些都可能引起海洋学家的兴趣。
