Typically, survival kits are designed to help you get through a situation in which help cannot be secured. However, if you equip yourself with a satellite phone you can contact help from anywhere on the planet. In other situations, a pre-paid cell phone or two-way radio (be sure to find out the frequency the local ranger station or emergency responders use) may be all that you need to contact help when you need it most.
Everyone in California is waiting for "The Big One," an earthquake with a magnitude of 8.0 or greater that will destroy infrastructure and cause mass panic. Yet when I moved to the Bay Area from the East Coast, I discovered that since most of the people I knew were making do with small apartments and ever-increasing rent, having supplies on hand for a natural disaster required a space premium that many couldn't afford. I began to put together an earthquake kit that would not only serve my household (which over the years fluctuated from one to three other people) but also my neighborhood, if needed. Even with all that work, I didn't consider myself a prepper, just someone who heeded the Red Cross's warnings.
