Seismology provides information on the structure and composition of the Earth’s deep mantle. Without accurate constraints on the elastic properties of deep-mantle minerals, however, the seismic dataset cannot be fully interpreted. This Technical Review outlines the current techniques that are used to investigate the elasticity of typical mantle minerals.
Advances in numerical methods and high-performance computing have enabled imaging of Earth’s interior across scales using the physics of seismic-wave propagation. This Technical Review summarizes the use of full-waveform inversion in controlled-source and earthquake seismology.
