Model Description

The starquakes of a pulsar have been considered as a source of repeating FRBs. The bursts of FRB 121102 are consistent with the aftershock sequence of an earthquake, where the burst’s time-decaying rate of seismicity falls within the typical values of earthquakes. They also show that the burst energy distribution of FRB 121102 has a power law form, much like that of the Gutenberg-Richter law of earthquakes. Further, the waiting time of bursts has a Gaussian distribution; another characteristic feature of earthquakes.

Observational Constraints

Starquakes are poorly understood, limiting the testability of this theory. They may be associated with SGRs, which offers counterparts for which to search.
