据美联社华盛顿1981年8月25日报道来自十一个国家的地球物理学家们运用美国卫星、深空射电信号和宇航员留在月球上的激光反射器,着手实行一项五年计划,最终目标是作出可靠的地震预报。该计划负责人、戈达德航天飞行中心的来德(G.Mead)强调指出,在这项耗资1～1.5亿美元的五年计划期间,他们并不期望能够做出这种预报,可靠预报也许将是一、二十年以后的事。他说:“这一研究将会增进我们对地球动力特性及地震机制的了解,并将最终能够 According to the Associated Press, Washington, August 25, 1981 Geophysicists from eleven countries embarked on a five-year plan using US satellites, deep-space radio signals and laser reflectors left by astronauts on the moon The ultimate goal is to make a reliable earthquake prediction. G. Mead, head of the program and Goddard Space Flight Center, emphasized that during the five-year plan of between $ 150 million and $ 150 million, they did not expect to be able to make such predictions and reliable forecasts Maybe it will be one or two decades later. He said: "This study will enhance our understanding of the Earth’s dynamic characteristics and seismic mechanisms and will eventually be able to
