Thanks for the info Don. In your post on July 31 you mentioned that the Macaama fault to the north of the Rogers Creek fault has been creeping. Must be a good bit of strain built-up on the Rogers Creek which is locked but is bounded by the two creeping faults- the Northern Hayward to the south and the Macaama to the north. I know the Green Valley fault to the southwest of the Rogers Creek has been creeping in the past too. Wonder if some of that strain is feeding onto the Rogers Creek of onto the West Napa fault?
Do you know off-hand of any studies of creep or of lack of creep on the West Napa fault? I'm going to try and do a look-up of it if you don't have any information easily available. Thanks.
