Hi All. Looks like the 34/36 degree ring from the Fox Island quake may have triggered a little action in the Fort Brag and Willits area. This ring is in the what is considered to be regional area by those who developed the “far field aftershock” map. Not sure that I agree with that, but for now I will use it that way.
The Willits area is somewhat an active area the Fort Brag Area isn't.
The “moment tensor solution” for the Willits quake shows it to be a strike slip with normal fault component. Most of the quakes in that area are strike slip and are associated with the Maacama fault. At present time I don't know the name of the fault the quake may have occurred on. It may not even be listed.
Some years ago Petra and I went on a walking tour in that general area. There are some roads in the area that are best traveled on during the dry season. Today's quake is a little more then a mile from the area we were in. There was a 4.1Mw in 2006. The growth in that area is pretty dense so it is a little hard to see anything with detail. Also makes for difficult in walking. My walking days are over. Sure do miss that. Take Care...Don

The Willits area is somewhat an active area the Fort Brag Area isn't.
The “moment tensor solution” for the Willits quake shows it to be a strike slip with normal fault component. Most of the quakes in that area are strike slip and are associated with the Maacama fault. At present time I don't know the name of the fault the quake may have occurred on. It may not even be listed.
Some years ago Petra and I went on a walking tour in that general area. There are some roads in the area that are best traveled on during the dry season. Today's quake is a little more then a mile from the area we were in. There was a 4.1Mw in 2006. The growth in that area is pretty dense so it is a little hard to see anything with detail. Also makes for difficult in walking. My walking days are over. Sure do miss that. Take Care...Don
