Hi Don and Petra. Don, I'm curious about the current readings at the Earthquake Tracker sites located in Parkfield and Coalinga. Do you happen to know if there is a problem with those particular locations? I seem to remember you saying that the one in Coalinga had been underwater or something but the readings seem to have changed so I am not sure if that issue was fixed or not. If the data is good, then I would imagine that the Parkfield Gap could be getting ready to produce a moderate-large event. The sites located between San Fran and Portola Valley seem to be rather quiet which is a good thing.
