  "abstract": "The starquake model of pulsar glitches is revisited in light of accumulated observational data. A statistical comparison between the time-predictable and the magnitude-predictable models, borrowed from seismology and grounded in the classical spring-slider framework, is performed against a sample of 245 glitch events from 9 pulsars. It is found that the data supports the time-predictable model, i.e., a quake resulting in a glitch could be triggered when the developed stress reaches a critical threshold, $τ_{\\rm c}$, while the remaining elastic energy (correspondingly the residual stress, $τ_{\\rm r}$) after quakes is not fixed. The critical stress could be the order of $τ_{\\rm c}\\simeq (10^{34}-10^{35})\\ {\\rm dyn\\,cm^{-2}}$ if the residual stress after a quake with maximum stress drops could be considered negligible (i.e., $τ_{\\rm r}\\simeq 0$), to explain the glitch amplitudes and the intervals. This $τ_{\\rm c}$-value is the order of the shear modulus of strangeon stars, but would be several orders higher than that of conventional neutron stars.",
