Hi All,

I had a very good right ear tone today which came in loud and strong for 5 seconds and then began to trail and stopped at 8 seconds.

For me this means I need to find a potential epicenter 187.5 miles south of my location at the time, which was in Petaluma.

10 Miles North of Middle Mountain is that distance. The coordinates listed below are at Middle Mountain. The magnitude is my best guess.
