hi everyone. A weird thing happened to me today and I just have to share. I'm in AZ. Was standing outside my daughters school just before 3p waiting for her to come out. I felt the ground underneath me vibrate. it was not my equilibrium. it was very strange. I put my hand behind me against the school wall and I could feel the vibration even more then between touching the wall and the ground at the same time. I looked at the other parents but no one seemed to notice it but me. it lasted less then two minutes. I don't know what that was. it wanted to let someone know it happened.
