A sudden change in a pulsar's period and spin-down rate believed to be caused by a starquake – the abrupt release of stress energy either in the crust of the star or between the crust and the superfluid interior. Glitches tend to occur in young pulsars, such as the Crab pulsar and Vela pulsar, whose spin rate is decreasing most rapidly.
