Charleston resident and Columbia native David “Apples” Appleton will be featured in an upcoming episode of “Doomsday Preppers.”

The National Geographic Channel’s hit series, which explores the lives of “otherwise ordinary Americans who are preparing for the end of the world as we know it,” premiered the first of four new episodes on Tuesday.

The second of the four premiers is titled “The Gates of Hell” and will air at 9 p.m. ET/PT Aug. 20. The episode will feature a Washington state resident named Steve and a life coach named Suzanne who are separately preparing for the chaos after an economic collapse, and South Carolina’s Appleton, who along with his wife, Lauren, is preparing for a catastrophic earthquake to hit Charleston.

While Charleston doesn’t jump to most people’s mind when you say “earthquake,” the area is actually quite seismically active, with the Department of Natural Resources website reporting five quakes in the state so far this year. But it’s the Charleston earthquake of 1886, which had an estimated magnitude of 7.6, that stokes the fear of another big one.

The Appletons have stored enough food and water to ride out the first 72 hours. Additionally, they have built a greenhouse to provide them with a food source and designed a “doomsday rickshaw” to use to escape quickly with whatever they can carry.
