Just thought I'd let you know that about 45 miles northeast of me were 2 small quakes early this morning .... 2:00 AM to 3:00 AM. I've had these ear tones like this all my life and never paid attention to them. Sometimes they are so strong I feel like I'm in a tunnel far away. The tone I described in the post was like the sound of a very large tuning fork and I want to say it felt like lots of pressure. That's about it. I'll keep up with these now. The magnitude 4 earthquake we had near Conway, AR recently was something I felt 2 days before and the ear tones and the feeling the earth move never happen simultaneously.
