Short summary
In this paper, the 3-D density structure of the Costa Rican subduction zone is modeled by means of interactive forward modeling of gravity data. The geometry of the subduction zone is constrained, among other geophysical data, by relocated earthquake hypocenters, taking into account intermediate depth seismicity which provides new information on the plate interface. In the preferred model, the presence of a continuous, steeply subducting slab is interpreted for SE Costa Rica.
