Let's not forget Snatcher Pot. Well worth a visit.
 
1.1 magnitude is a very small quake, somewhere about the same energy release as a Transit sized van crashing from motorway speed. I wouldn't expect any effect 10km away even if that 10km is vertical.

There are old faults almost everywhere, an event as small as that wouldn't necessarily be on a known or recently active fault.
