The warning system works by detecting primary waves , which spread from the epicenter of a quake and travel faster than the destructive shear waves 预警系统的工作原理是探测地震纵波，纵波由震中传出比破环性的横波传播速度快。
The warning system works by detecting primary waves , which spread from the epicenter of a quake and travel faster than the destructive shear waves 预警系统的工作原理是探测最初从震中传出的地震波，其速度要比破坏性的剪切波快。
The warning system works by detecting primary waves , which spread from the epicenter of a quake and travel faster than the destructive shear waves 预警系统通过监测从震源发出的纵波来工作的，纵波比具有破坏性的横波传送的更快。
The warning system works by detecting primary waves , which spread from the epicenter of a quake and travel faster than the destructive shear waves 这个预警系统靠侦测主要的地震波工作，主震波由震中传出比破环性的波传播速度快。
The warning system works by detecting primary waves , which spread from the epicenter of a quake and travel faster than the destructive shear waves 预警系统通过探测原始地震波工作，那种从振中发出并且传播速度比具有破坏性的波快。
The warning system works by detecting primary waves , which spread from the epicenter of a quake and travel faster than the destructive shear waves 预警系统的工作原理是探测主要的地震波，主震波由震中传出且比破环性的波传播速度快。
News agencies in indonesia reported over 4 , 000 dead , many of them in aceh , in northern sumatra , about 160 kilometers 100 miles from the quake ' s epicenter 印度尼西亚苏门答腊岛附近海域当地时间26日上午8时发生里氏8 . 5级的强烈地震。
And because the ocean bottom near the epicenter thrust upward , the planet ' s water now has less room , causing the sea level to rise by about a millimeter 而由于靠近震央的洋底逆冲而上，使容纳海水的空间变小，造成海平面上升了约一公? 。
Furthermore , the above recording data limited to a single point is not valid to predict the epicenter . in this thesis , seismic infrasound is profoundly studied 本课题正是在以上的前提下，对临震异常次声进行更深一步的研究和探讨。
The warning system works by detecting primary waves , which spread from the epicenter of a quake and travel faster than the destructive shear waves 预警系统是根据探测来自于震中的地震纵波来运作的，它的传播速度比破坏性大的横波传播速度要快。
