然而，仪器的如此描画只能记录地震波运动中的水平方面的运动部分，而地震波运动实际情况复杂得多。
The apparatus thus described, however, records only the horizontal component of the wave movement, which is, in fact, much more complicated.
研究发现地震波参数空间分布图能有效地确定预测地震的地点，而地震波参数时序与空间图的有机结合将对判定地震震级和发震时间起到积极作用。
The author has found the spatial distribution of seismic wave parameters can determine the place of predicting earthquake, and it is useful to determine the magnitude and time.
美国中部及东部的遇到的有关地震的问题是双重的：地震波在这部分古老而寒冷的地面上传播的较快，所以危害传播得更广。
The problem with quakes in the central or eastern us is two-fold: Seismic waves travel farther in the colder, older crust under that part of the country, so the damage can be more widespread.
地震产生的冲击波在地面上迅速移动，不过电信号传递地更快，这使得预警信号能够超过地震波而传递到当地的民众那里。
Shock waves from a quake move quickly through the ground, but electronic signals are far faster, allowing warnings to outrun temblors.
