I grew up in the SF bay area and been through my share of earthquakes and the Portland/ Vancouver area according to geologists is due for a big one anytime now so here's some tips I learned the hard way. 1. it's a "bug in" scenario don't expect to be able to travel but in the event that your home gets red flagged by the city have a 72hr bag ready with cash (most likely power will be out). 2. Keep shoes and a flashlight by your bed walking through broken glass "die hard" style is no fun. 3. If you can fill up your bathtub or have an emergency water supply ready and easy to get too. (if the water lines aren't already damaged the aftershocks might do them in) 4. be prepared for looters it can and will happen if it's bad enough have a proper escalation of force ready. My garden was raided by a neighbor down the street. 5. A emergency toilet and lime powder comes in handy. The 5 Gallon style works fine. 6. Local emergency services will be temporarily unresponsive have a fire extinguisher and medical supplies on hand especially splints. 7. battery powered radio. 8. during the quake all standard rules apply (stand in a door way under a desk ect.) helmets also come in handy. 9. If your in the National Guard or any reserve component be on standby you will get a call. Anyways I hope this rambling helps some of you out and to others I'm sure you've heard this before feel free too add any advice from experience or common sense. Stay safe.
