Thrust earthquakes at subduction zones are the largest on Earth, and can have devastating consequences. We now recognize that the slip behavior of these important faults can be highly variable in both space and time. Precise space geodetic measurements are one of the best tools available to study and characterize these history of slip. The surface displacements due to slip are mixed together in geodetic time series with other signals: time-varying surface loading and volcanic deformation, and other components that are largely steady in time such as long-term deformation of the overriding plate, glacial isostatic adjustment, etc. Thus the study of subduction zone slip generally requires using a broad range of geodetic tools to isolate the desired signals.
