Some evangelical Christians hold to an interpretation of Bible prophecy known as the post-tribulation rapture, in which the world will have to go through a seven-year period of war and global dictatorship known as the "Great Tribulation". Jim McKeever helped popularize survival preparations among this branch of evangelical Christians with his 1978 book Christians Will Go Through the Tribulation, and How To Prepare For It.
Gerald Celente, founder of the Trends Research Institute, noted how many modern survivalists deviate from the classic archetype, terming this new style "neo-survivalism"; "you know, the caricature, the guy with the AK-47 heading to the hills with enough ammunition and pork and beans to ride out the storm. This [neo-survivalist] is a very different one from that".
Huffman, who lives in San Francisco, has large blue eyes, thick, sandy hair, and an air of restless curiosity; at the University of Virginia, he was a competitive ballroom dancer, who hacked his roommate’s Web site as a prank. He is less focussed on a specific threat—a quake on the San Andreas, a pandemic, a dirty bomb—than he is on the aftermath, “the temporary collapse of our government and structures,” as he puts it. “I own a couple of motorcycles. I have a bunch of guns and ammo. Food. I figure that, with that, I can hole up in my house for some amount of time.”

While survivalists accept the long-term viability of Western civilization, they learn principles and techniques needed for surviving life-threatening situations that can occur at any time and place. They prepare for such calamities that could result in physical harm or requiring immediate attention or defense from threats. These disasters could be biotic or abiotic. Survivalists combat disasters by attempting to prevent and mitigate damage caused by these factors.
Before I headed back to Wichita, we stopped at Hall’s latest project—a second underground complex, in a silo twenty-five miles away. As we pulled up, a crane loomed overhead, hoisting debris from deep below the surface. The complex will contain three times the living space of the original, in part because the garage will be moved to a separate structure. Among other additions, it will have a bowling alley and L.E.D. windows as large as French doors, to create a feeling of openness.
This group stresses being able to stay alive for indefinite periods in life-threatening wilderness scenarios, including plane crashes, shipwrecks, and being lost in the woods. Concerns are: thirst, hunger, climate, terrain, health, stress, and fear. The rule of 3 is often emphasized as common practice for wilderness survival. The rule states that a human can survive: 3 minutes without air, 3 hours without shelter, 3 days without water, 3 weeks without food. 
People who carefully and painstakingly prepare for mass extinction don't exactly seem like the type of people who plan great parties. At least, with those vast collections of guns, ammo, and other terrifying armaments, I certainly hope not. Then again, I suppose everyone will need a drink or 10 to get through the inevitable horrors of forever navigating the "what's for dinner" question without Seamless or, you know, realizing that your urban-dwelling family members will probably never arise from the blasted pit of rubble where their apartments once stood.
If the fire is around you and you can’t escape, you don’t have many options, says Shane Hobel of the Mountain Scout Survival School. If there’s a pool or a pond nearby, jump in and try to wait it out there. Otherwise, if you have time, dig a trench that’s two to three feet deep and long enough for you to lie in. Soak a blanket in water, wrap it around yourself, and lie down in the trench. It’s risky, but at least you’ll have a chance.
