国际地震学与地球内部物理学协会(IASPEI)第25届大会于1989年8月21日—9月1日在土耳其最大城市伊斯坦布尔的国文文化中心(Atatürk Cultural Center)举行。这次大会组织了15个专题讨论会,包括:IASPEI 的科学领域;活动陆缘的细结构和过程;俯冲块体动力与地球深部;大地动力过程:定量模型与新的地球物理约束;岩石圈中不连续界面的物理学与岩石学性质;阿尔卑斯-喜马拉雅及其它造山带的地震构造;震源模拟;用数字地震图确定震源参数;地震预报与前兆现象;板缘地区的地震危险性评定;大地震场地地面运动的估计;在二维和三维结构中地震波场的计算与解释;地震波的散射与衰减;地热模拟的正演与反演技术;地热与其它参数的关系。及9个研讨会,包括,走时表与地震定位问题;区域资料中心;发展中国家的仪器与数据分析;岩石圈的综合编图;地壳形变;地震危险性评定技术;地震统计与时间可变的危险性;国际地震观测期(3年);非洲地震学与有关科学。另外还专门组织了一次1988年12月7日苏联斯皮塔克地震的学术报告会。在这次大会上宣读的论文近600篇,另约有150篇论文以张贴图文的方式进行了展览公布。各国注册的地震学家以美国为最多,有62人。日本次之,44人。再其次是西德、英国。我国与会人数有20人,其中有国家地震局派出的一个由12人组成的代表团。下面将分别概述有关的专题讨论会和研讨会的具体内容。

The 25th General Assembly of International Association of Seismology and Physics of the Earth's Interior (IASPEI) was held at the Atatürk Cultural Center of the biggest city of Istanbul,Turkey from August 21 to September 1,1989.Fifteen special academic sub- jects were organized by the General Assembly,including scintific horizons of IASPEI,detai- led structure and processes of active margins,the earth's deep interior and dynamics of sub- ducting slabs,geodynamical processes:quantitative models and new geophysical constrain- ts,physical and petrologycal nature of discontinuities in the lithosphere,seismotectonics of the Alphine-Himalayan Belt and other major orogenies,modelling the earthquake source, determination of source parameters using digital seismograms,earthquake prediction and premonitory phenomena,earthquake hazard assessment in the interplate section,estimation of site specific ground motion for large earthquakes,computation and interpretation of seis- mic waveforms in 2-D and 3-D structures,scatering and attenuation of seismic waves, forward and inverse techniques in geothermal modelling,correlation of geothermal and other parameters.And 9 workshops were also organized,they are:travel time tables and earth- quake location,regional data centers,instrumentation and data analysis in developing coun- tries,comprehensive mapping of the lithosphere,crustal deformation,earthquake hazard assessment techniques,earthquake statistics and time dependent hazard,international seis- mological observing period (three years),African seismology and its related sciences.In addition,a special academic talk on the Spitak earthquake of Desember 7,1988 was also organized.About 600 papers were read at the General Assembly.And about 150 papers were shown by posters.The United States leads in the number of representatives registered (62); the second country is Japan (44) and the third is West Germany and USSR.Twenty Chinese representatives were sent to attend the General Assembly,of whom 12 were members of the delegation sent by the State Seismological Bureau.The paper overviews respectively the specific contents of every seminor on each of the scientific subjects.
