摘要
本文以IASPEI的“地震波的散射与衰减”专题报告会为主,评述了近几年在地震波散射方面的研究进展.述评所涉及的方面有:1.关于地震尾波的起源;2.大震前尾波包络的前兆性变化;3.地震尾波包络衰降的机理;4.区分散射和吸收的新方法;5.新领域的开拓和研究.
The recent progress in the research of seismic wave scattering is reviewed based on the presentations at the Symposium 'Scattering and Attenuation of Seismic Waves' of the 25th IASPEI General Assembly. The review includes 5 topics: 1. The origin of seismic coda; 2. Precursory changes in coda envelope decay before a large earthquake; 3. Mechanism of coda envelope decay; 4. New method of separating scattering and absorption; 5. Exploring new fields of study.
