Seismic tomography is a powerful tool for imaging the Earth’s interior and inferring its structure, composition, dynamics and evolution. Over the last decades, our images have sharpened, thanks to the growth of global and dense regional networks (on land and in the oceans), the extraction of new observables, advances in modelling techniques and increased computational power. We are now not only resolving unprecedented details on local and regional scales, but also moving towards whole-Earth tomography, including the inner core.

We welcome contributions on methods and applications of seismic tomography from the crust to the core and at scales from local to regional to global, including studies of new observables, developments in forward modelling and inversion techniques, innovative approaches to uncertainty quantification, and seismological and interdisciplinary efforts aimed at obtaining new insights into Earth's dynamics and evolution. While we welcome all studies aimed at constraining Earth structure, we particularly invite contributions that utilise passive sources.
