英文摘要 | To constrain the poroelastic component of postseismic deformation, we model the subsurface hydrologic response to the M-w 7.6 subduction zone earthquake that occurred on the plate interface beneath the Nicoya peninsula in Costa Rica on 5 September 2012. The model shows that poroelastic relaxation occurs on multiple time scales and the associated deformation can be up to 2 cm for the trench-perpendicular component. By modeling the time-dependent deformation associated with poroelastic relaxation, we can begin to remove its contribution from the observed geodetic signal. Inversions for after slip that ignore poroelastic deformation have errors of 10-20% overall and up to 50% locally. Poroelastic effects can both mute and amplify the inferred afterslip. |
