地震波は地球内部の不均質構造や振動の励起源に関わる情報を豊富に含んでいる．その豊かな情報を適切に解釈し利用するためには，固体力学や流体力学，波動論等に基づく数理的・数値的研究，岩石試料等を用いた実験的研究，観測データ解析等の，多様なアプローチに基づく知見が必要である．さらに，近年の観測技術の進展にともない，地震波のみならず，津波や気圧波等の様々な波動現象に関わる大量かつ良質なデータが蓄積されてきている．これらのデータを適切に解釈し，固体地球に関わる波動現象を包括的に理解することが，新たな研究分野を切り開くことにつながる．このセッションでは，地震学・物理探査学の分野を中心に，波動論に基づく理論的・実験的研究や，観測データを用いた地球内部構造の定量的理解，様々な自然現象・社会現象に起因する振動励起源の解明等の，固体地球に関わる波動現象を対象とした研究を幅広く募集し，その総合的な理解を深めることを目的とする.

Seismic waves contain a wealth of information related to heterogeneous structures of the Earth's interior and the excitation sources of oscillation. To appropriately interpret and utilize this rich information, various approaches are required, such as mathematical and numerical studies based on solid mechanics, fluid dynamics, and wave theory, as well as experimental research using rock samples, and analysis of observational data. Moreover, recent advances in observation technology have made available large amount of high-quality data, not only on seismic waves but also on other wave phenomena such as tsunamis and atmospheric pressure waves. A comprehensive understanding of these wave phenomena will lead new research fields related to the solid Earth. In this session, focusing on the fields of seismology and geophysical exploration, we aim to deepen our comprehensive understanding of various wave phenomena related to the solid Earth. This includes theoretical and experimental research based on wave theory, quantitative research of the inner Earth structure using observational data, verification of various natural and social phenomena that excite vibrations in the Earth, and so on.
