a small swarm has been going on in Dublin, CA in the last few days. Since I'm about 1 mile from the locations, I'm keeping my eye open.

Unfortunately I haven't had time to learn how to read the motion mechanisms. I know Don has in the past identified the type of fault and sometimes name based on that info.

Can anyone fill me in on the fault type and the north and south trend? it's too far away for the Calavaras. Largest so far is a 3.1
