These waves might originate from natural phenomena such as earthquakes or from  man-made sources such as controlled explosions.

这些波可能源自自然现象如地震，或源如控制爆炸。

Her proposal that the lights and other strange activity trace to quakes is reasonable, says Yuji Enomoto. He's an earthquake scientist at Shinshu University in Matsumoto, Japan.

恩本堂（音译）表示，赫夫提出的灯光及其他常现象源于地震的假设是合理的。他是日本松本信州大的地震。

In addition to unmasking new seismic phenomena, the study also demonstrates how seismic data could be used to track human activity and movement — like traffic patterns in a certain region, for example.

除了揭开新地震现象的面纱，该研究还证明了如何利用地震数据追踪类活动和移动——比如某个地区的交通模式。
