@kdfrawg We get the occasional one, the most memorable of recent quivers was a 7.6 some 10 km underground, about 50 to the southeast. A friend on Twitter likened the experience to that of sitting atop a washing machine on its spin cycle.
It went for at least 35 seconds and rather than being the normal up & down thumpy bumpy action it was as my friend described: a squirming, twisting motion. Really weird. There were a number of rural roads closed thru landslips around the epicentre.
