Abstract;An earthquake is faulting in the Earth. Seismic waves from it propagate through the Earth, and reach the Earth's surface generating seismic ground motions. Thus, seismologists observe these ground motions using seismographs, and carry out inversion of them for investigating the faulting and the Earth's structure. Hypocenter determination is the most basic inverse problem for the earthquake itself, and has developed into the centroid moment tensor inversion and source process inversion. Seismic tomography and inversion of free oscillation and surface waves are inverse problems for the Earth's structure. (author abst.)
