In a previous post I described how the quakes I've been following on the Pacific Subduction Zone have been occuring mostly on the northern end of Vancouver Island or near Ferndale California at the southern end, leaving most of the Subuction Zone in between rather quiet. As I explained in the previous post this could be a problem. The quakes are easing pressure, but they appear to be easing pressure mostly at the northern and southern ends of the Zone. Well, good news, there was a 4.9 on the Zone west of Bandon Oregon yesterday (May 20). That contributes to easing pressure on the middle of the Zone. The only problem is that it's just one out of the last 12 quakes over the last year. And it continues the rate of one a month.
