Model setup. (a) Dimensions of the domain and the layers. Two white arrows indicate the locations of the magma chamber and the nuclear test site. The symbol ’N’ denotes the north for approximate geographic reference. (b) Mesh for the domain shown in (a). Arrows indicate the surface locations corresponding to DNH and YNB stations. (c) Enlarged views of the mesh around the magma chamber and the explosion site. \label{fig:model_setup}
