Topography‐Incorporated Adjoint‐State Surface Wave Traveltime Tomography: Method and a Case Study in Hawaii

S Hao, J Chen, M Xu, P Tong - Journal of Geophysical …, 2024 - Wiley Online Library
In this study we recast surface wave traveltime tomography as an inverse problem
constrained by an eikonal equation and solve it using the efficient adjoint‐state method …

Comparative analysis of eikonal‐based first‐arrival tomography: A case study from the Santos Basin, Brazil

PHB Alves, M Cetale, SLEF da Silva… - Geophysical …, 2024 - Wiley Online Library
We compare classical and adjoint‐state first‐arrival tomography approaches in subsurface
model reconstruction, focusing on pre‐salt updates with a circular‐shot ocean bottom node …
