Good Morning Sacramento
I wish I was mored educated about things geological. but if you heard it ,,,you heard it.
We live east of Sacramento and a bit closer to Napa. My wife woke me up that morning and was almost hysterical because she had heard an animal in the closet near our bed. I finally convinced her to just slide the closet door back so we could see what was there. When she did slide the door open and we saw her dresses swaying to and fro we immediately knew there was an earthquake from our past living in the east bay area.
