Some humans still can sense when a EQ is about to happen... I lived in So. Calif. near the San Andreas fault for many years and after realizing that I was experiencing nervous energy, grinding my teeth, slight nausea and then having a EQ within 12-24 hours several times, I was more tuned into them. At first I just kept it to myself, because I thought I was imagining things, but then I started telling people, and now even though I live in AZ, my friends and family still rely on me to forwarn them. The most recent EQs, like Baja, and Eureka I was a wreck before they happened.
