I'm a very visual person ad when I see things lining up I notice it - as in it sticks out. It probably means nothing, but the patterns lately have been in places I don't remember ever seeing before. Granted, it could be drilling and all that it brings, or it could be something shifting around or waking up. Correct me if I'm wrong but the weight of water has been known to trigger small-ish quakes (lss than 5.0's) when filling reserviors -yes? Of course such would be more of a localized, rapid fill...
