地球动力学过程中的波动现象及其在地震预报中的应用

讨论了地球内部的波动现象与构造及地震间的关系。引进了４类广义构造波。它们是：表现为地球不同年代的综合构造运动结果的超长周期构造波；由地震活动性迁移，即所谓地震活动波所反映的长周期（不同类型与不同速度的，周期从几年到几十年）构造波；由地震前兆三阶段发展过程反映出的中等周期（从几月到几年）构造波；以及由地下水位、地倾斜、重力、地震波、电磁辐射、地声等的变化所记录的短周期（从几分到几天）构造波。地震活动波又有３类，可分别用广义瑞利型构造波、广义洛夫型构造波及广义导波型构造波来解释。最后，研讨了地球内部波动现象在地震研究中的应用，包括它们在地震危险性分析与地震区划、地震预报以及地震成因研究中的应用。

WAVELIKE PHENOMENA IN GEODYNAMIC PROCESSES AND THEIR APPLICATIONS IN EARTHQUAKE RESEARCH

Tea relatiohehips between wavelike phenomena in the earth's interior,tectonic structure and earthquakes are dicussed. FOur types of generalized tectonic waves are introduced. They are: the ultra-long-period tectonic weves which are synthetical tectonic results in different earth history;the long-period (from several year. to tens of years of different kinds and velocities) tectonic waves reflected by migrtions of earthquake activity,so-called seismicity waves;the medium -period (from several months to several years )tectonic waves reflected by three threestage development process of earthquake Precurors; and the short-period (from sereral minutes to seseral days)tectonic waves recorded by changes in ground water level.tilt,gravity,seismic waves,electromagnetic radistiou,earth sound,and the others. Seismicity waves of three types are interpeted as generalized Rayleigh tectonic weves,generalized Love tectonic waves and generalized channel tectonic waves. Finally,the applications of wavelike phenomena of the earth's interior to earthquake research is discussed, including seismic risk analysis and seismic zoning,earthquake prediction and seismogenesis researches.
