Very few seismograms showing motion near to the source are available.

可以利用的记录震源附近运动的地震图很少。

Theoretical reflection seismograms in dynamite source condition are formed by using anisotropic reflectivity method.

本文用各向异性反射率法计算爆破源反射地震的理论地震图。

Let's guess an origin time of 10 seconds, measured on the same clock that made the time scale at the bottom of the figure and timed the seismograms.

让我们猜测地震的起源时间为10秒，在同一个钟上测量，使得时间刻度在图表的底部，让地震图同步时控。

He has also been able to process seismograms and identify differences between the seismic signals from earthquakes that produce tsunamis directly and those that trigger tsunami-producing landslides.
