Young magnetars with strong and highly multipolar crustal magnetic fields can experience significant field rearrangements timescales of <~100 years. Magnetic stresses then occur throughout the outer layers of the star, potentially causing frequent crustal failures. The bursts of FRB 121102 and FRB 180814.J0422+73 are consistent with this picture.
