Todd, that had not really struck me this time, but OK. It does seem like seismicity turns on and off to some extent in California, but I could be fooling myself and have not done anything scientifically with this. It seemed like the global seismicity was in a bit of a cluster with several 6s the last couple days, but when Roger checked some circum-Pacific stuff to see if there were clusters I think he came up with no relation.
