| Abstract: | 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. |
