美国科学家们说,他们通过使用包括计算机、激光和测量地表下面200米深处的岩石运动的灵敏地震仪器的新技术可做出成功的长期地震预测。美国地质调查局的官员说,中国、日本、苏联和美国等一些国家在过去的十年里开展了重大的研究计划。结果,在地震预报研究方面取得了某些显著的成就。地震学家们于1981年就警告说,墨西哥西海岸地区很可能会发生显著的地震活动。结果,
American scientists say they can make successful long-term earthquake predictions by using new technologies that include computers, lasers, and sensitive seismic instruments that measure rock motion 200 meters below the earth’s surface. Officials at the United States Geological Survey said that some countries such as China, Japan, the Soviet Union and the United States have conducted major research programs in the past decade. As a result, some remarkable achievements have been made in the study of earthquake prediction. Seismologists warned in 1981 that significant seismic activity is likely to occur on the western coast of Mexico. result,
