Can't sleep, so I may as well share what I learned while living on the San Andreas for 20+ years. - little things to watch for that will pretty much indicate a coming quake.
1. Watch the animals. Sea gulls will fly inland and fly in circles. Birds will become way more vocal. Ants will come out of the ground and move into your house. LOL - like they do before very rainy weather. Dogs will run away - check the lost and found ads in your area. Cats (for some reason) sometimes come down with urinary infections.
2. People become way more argumentative - especially on the internet. Road rage increases.
3. Because the electro-magnetics change, there may be airplane crashes or train accidents... it seems to affect metal structures. Also, you might see light flashes - earthquake lights.
4. Some people become very hyper.
There's more... but I'll have to try and remember. LOL I thought I'd never have to think about this shit again !!
bump to get the advice out
