据檀香山夏威夷大学的地球物理学家们认为,在世界海洋的海底,地震活动可能远比通常所认为的要活跃得多。这些研究人员说,太平洋发生着地震,而世界地震台网却一直未检测到这些地震。这些地震之所以未被检测到,可能是因为它们未产生正常类型的地震波。夏威夷大学地球物理研究所的沃克(Da-niel Walker)说,“海洋被认为是无震的,但我们相信,如果在深洋盆地放置地震仪器,那么就会出现一个完全不同的图像。”他说,板块运动施加给海洋岩石圈板块的应力远比通常所认为的大得多。岩石圈是地壳的外部刚性部分。沃克和该研究所的另一位地球物理学家克 According to geophysicists at the University of Hawaii, Honolulu, seismology may be far more active than commonly thought at the seabed of the world’s oceans. The researchers said earthquakes in the Pacific Ocean have been undetected by the world seismological network. These earthquakes were undetected, probably because they did not produce the normal type of seismic waves. Da-niel Walker of the Institute of Geophysics at the University of Hawaii said: “The oceans are thought to be Earthquake-free, but we believe a completely different picture will emerge if we place a seismic instrument in a deep-ocean basin.” He Said that the stresses applied by plate motions to marine lithospheric plates are far greater than what is generally believed. The lithosphere is the outer rigid part of the crust. Walker and another geophysicist at the institute g
