So I've been watching the Hayward Fault very closely last few months. AFter reading countless articles about it being at its 140 year mark, along with evidence that the 10 years prior to the 1868 quake and its relationship with the Calaveras fault I've noticed some interesting things.

Activity in the past 2 months on the calaveras where its thought to be influential with the Hayward fault has been increasing. There's been one 4+, several 3s and countless micros. I also believe this is the same area that had the 5.6 back in 2007. I'm probably wrong, but, this area seems worth looking at and I'm thinking these are all precursors to something bigger on the southern Hayward fault.
