地震记录的

According to the three-components teleseismic records from portable digital seismic station deployed in Himalaya mountain chain region, the S-wave velocity structure beneath 46 teleseismic stations are investigated by using transform function method and SA technique. As reliable geophysics evidence, these results help us to understand the geodynamic process of Himalaya mountain region of Tibet.

利用流动数字地震台网提供的三分量地震波形记录，应用转换函数及快速模拟退火算法对喜马拉雅山脉地区46个地震站下的地壳横波速度结构进行了反演，为进一步揭示青藏高原喜马拉雅山脉地区的动力学演化过程提供了可靠的地球物理证据。

The San Francisco earthquake registered 7.8 on the Richter scale, making it a major earthquake.

旧金山地震在里氏震级的记录中为7.8，是一场大地震。

The forward modeling was applied to obtain the seismic synthetic seismogram of formations with different fluids and seismic attribute analysis was carried out on this basis.

采用正演模拟方法获得了含不同流体地层的地震合成记录，并在此基础上进行了地震属性分析。

In terms of the documentation frequency of these historical data on earthquakes of 4.7 magnitude or above in the past 3000 years ( Table 5 ) the frequency was below 2 times per 10 years for most of the time before the Song Dynasty; when printing was invented in the Song Dynasty the frequency increased to 3 times per 10 years; after the invention of seismoscope in 1900 it reached 100-1000 times per 10 years.

从3000年来4.7级以上的(ji2 yi3 shang4 de0)历史地震的史料记录频度看（图5），宋朝以前的绝大部分时间都在（2次/10年）以下；宋朝出现了印刷术，记录频度增到（3次/ 10年）以上；1900年后现代地震仪问世，记录频度达到（100-1000次/10年）的高水平。

The geologic record indicates that a catastrophic quakehits Cascadia only about every 500 years but the cities of the PacificNorthwest like Seattle and Vancouver are far less prepared than SanFrancisco and Los Angeles for a major earthquake so when the nextpowerful temblor comes around the region could suffer.

地质记录表明这里每500年才会发生毁灭性的地震。西北太平洋沿岸的城市，如西雅图和温哥华，都不像旧金山和洛杉矶那样对地震准备充足，所以下一次爆发大地震时，这一块地区很可能受灾严峻。

Even so, the total amount of air that is higher than the hundred-mile Instruments record some half-million seismic or microseismic disturbances of Earth each year.

据仪器记录，地球每年受到约 50 万次地震或微地震的打扰，其中有 10 万次被人感觉到，有 1，000 次造成损害。

Both China and Iran are in seismically active areas, have very long historical records, and have had many catastrohic earthquakes.

中国和伊朗都在地震活跃地带，有着悠久的地震历史记录，都发生过许多灾难性的地震。土耳其也如此。
