Editorial on the Research Topic Reverse Time Imaging in Solid Earth and Exploration Geophysics BACKGROUND Our knowledge of Earth's interior structures and properties has been based, for a significant portion, on findings in solid Earth and exploration geophysics. As likely the most popular geophysical tool, seismic imaging has been providing evidences for revealing the nature of Earth structure and geodynamics, for exploring natural resources such as water, petroleum, coal, and minerals, and

To better live with the nature, we must balance human activities between taking natural resources and minimizing human impacts on the environment. High fidelity seismic images of Earth's interior are useful to all of these efforts. MOTIVATION FOR THE TOPIC Reverse time imaging (RTI) was conceptualized in 1980s as reverse time migration (RTM), to map reflectivity structures and seismic sources via modeling time reversed seismic waveforms. Constrained by the limited computing power in the past, RTI has not become a leading way of seismic imaging until this century. With the growing demands for high-fidelity seismic images, it is timely that we present some of the latest advances in RTI.
