The starquakes have been considered as a source of repeating FRBs. The aftershock sequence of an earthquake, where the burst’s time-decaying rate of seismicity falls within the typical values of earthquakes. The burst energy distribution of FRB 121102 has a power law form, much like that of the Gutenberg-Richter law of earthquakes. The waiting time of bursts has a Gaussian distribution; another characteristic feature of earthquakes. 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.
Starquakes may be associated with SGRs or magentar flares, which offers counterparts for which to search.
