For Richard Duarte, surviving the end-of-the-world-as-you-know-it isn't just a possibility; he's lived it. In 1992, he and his family fled their home in South Florida with only the clothes on their back, after Hurricane Andrew swept through and destroyed their house. Half an hour after the storm passed, and long before rescue or cleanup teams arrived, looters entered his neighborhood.

"Your whole world is turned upside down," says Duarte, an attorney and author of two survival books, including his newest one, Quick Start Guide: Surviving an Urban Disaster. "Living in Florida, I knew Andrew wouldn't be the last disaster, so I've done a lot of research since to find out what the average person can do."

When you think "Doomsday preppers," you may think of survivalists building underground bunkers, stocking up on a several years' worth of food, or arming themselves against marauding mobs. And some certainly are doing that. But "prepping" takes a variety of forms and being prepared for a worst-case scenario isn't as out there as it may seem to some. Whether it's a natural disaster, terrorist attack, or pandemic — or the loss of a job, or the death or disability of the family breadwinner — you aren't likely to regret time spent on basic preparation.

Get Organized

Richard Duarte More

"Legal and financial preparations are probably the most neglected," says Duarte, a Miami-based attorney. "People are busy with their lives they've got a million things going on," he says, and essential tasks are often neglected. He explains that every crisis or disaster is also followed by a rebuilding and reconstruction phase. "If you go through an event like I did where the house is blown away, you won't have the access to those documents," he says.

Organize your documents into three categories:

crucial

important

nice to have

Crucial, for example, would include your will, power of attorney and the title to your home or car, for example. Start there and make copies. It's also a good idea to back those up digitally, either on a removable hard drive or flash drive. Then make sure the originals are stored in a separate, safe place, such as a safe deposit box.

Duarte has also been a victim of identity theft — it took him a year to straighten out — so he's especially conscious of the need for being organized financially. He also advocates the use of strong passwords to help reduce the risk of ID theft.

Stash Some Cash

Keeping some cash on hand can be helpful. "One of the biggest vulnerabilities we have as a society is that everything is electric," he says. "There are very few things that will work if there is a widespread power outage in a large metropolitan area." ATMs can go down, and store clerks won't be able to run credit cards. So he recommends keeping some small bills in your purse or wallet in case you need to catch a cab or put gas in the car, for example, and keep some cash at home.

Many preppers recommend stockpiling gold or silver in case of an economic collapse where currency loses its value. Duarte doesn't have a problem with owning these precious metals as a way to diversify an investment portfolio, but he is skeptical about their usefulness in day-to-day transactions after a disaster. "Folks can't eat gold and silver," he says.

Remember the Essentials

Food and water are essential to survival, so having enough on hand to survive a Katrina-like event is wise. The core survival elements, Duarte says, are "food, water, first aid, shelter, self-protection, temperature regulation and sanitation/hygiene and knowing when to stay put and when to get out." Store at least one month's worth of emergency supplies if you can, but if you can't, start with a smaller amount and work your way up. For example, on his blog he recommends spending an additional $10 a week on groceries that store well, and then rotating unused items into the menu periodically so they don't expire and go to waste. A first aid kit is also a must-have. And you'll need to think about how you'll protect yourself in dangerous situations.
