If you've got bookcases or pictures that can be shaken over or down start earthquake-proofing your home. Keep your slippers by your bed, (there'll be shattered glass on the floor), and a flashlight handy. The one shown in the pic is a windup flashlight with built in radio, charger for your phone and even a siren. My friends in Napa lost power at their home for days after the earthquake there last year and their cell phone eventually went dead. Have a container with supplies, (food, water, manual can opener, light sources, First Aid kit, batteries, etc. etc.), for you and your beloved(s) stocked. We'll post more information on what the Community Emergency Response Team, (CERT), recommends permanently on this website.
Best of all, take the CERT course and be ready to help both yourself and your family, (including your pets), and your neighbors.
