title: GEOPHYSICS: Enhanced: A Strained Earth, Past and Present.
abstract: Plate tectonics leads to deformation within converging or transforming plates, but the rates at which this happens are difficult to evaluate. In this Perspective, Ramsay highlights a new technique reported by Müller et al. for overcoming this problem in past and present mountain-building regions, which have particularly complex deformation patterns.
