I 've got seismographs all over the valley.compare the readings .
整个山谷都有我的地震仪。比较一下地震仪读数。
What the hell do we know about seismographs ?
我们对地震仪懂什么?
The push and return happen at approximately 12 hour intervals , and at times this shows up on the live seismographs and earthquakes that accompany a violent push and bounce back so precisely as to not be denied .
