It could be that my favoritest guilty pleasure is the consumption of disaster movies. Mostly I love them because of what I learn so that I may be prepared when that next Meteor/Tsunami/Alien Invasion/Tornado/Earthquake/Monster/Climate Change comes along. How else are we going to be ready? I don't see any real guides out there. Who else do we have to turn to except these masterworks? Watch and learn... so that the next time your windows start to shake or a giant fireball appears perfectly framed on the horizon, you will know just what you need to do to survive.
Own A Dog
If you look at the evidence - and I have - the odds are the greatest that your dog will survive whatever terrible set of life-threatening circumstances any given disaster offers. Sure, owning that dog will put your own life in danger for when the time comes you have to go save it -- but trust me, it may seem impossible that you will be able to save your dog in time... but you will. Dogs cannot die in disasters. They can outrun fireballs, survive F5 tornados and sniff out invading aliens. So hang on to Fido, because as long as he's with YOU, you're going to be ok.
Note: Whatever you do, don't hand him over a closing pressurized saftey gate! You're toast as soon as he leaves your hands.
This could technically fall into the same category as dogs. If you have a kid, there's no way that kid is going to die. Just trust me. Kids can't die in disasters. Stick close. Possibly duct-tape that child to your torso if you need to.
If you have neither a dog, nor a child, I recommend finding a family with one or both... preferably a family where the parents are divorced and -- this is important -- the ex is not nearby.
Press The Accelerator
The evidence of many a disaster film is clear on on this point. It distinctly shows that it pays to drive really, really fast in any given disastrous situation.
I know and you know that things like pyroclastic flow can travel at upwards of 700 mph or that your tires would melt if you drove anywhere near lava... but don't worry. Press the accelerator. You'll make it. Is it a bus or a camper? Don't worry. Gun it. You can jump over caverns, buckling asphalt, falling bridges... you can outrun a shockwave in a station wagon if you just. Press. The. Accelerator. Same applies for airplanes, boats and trains. Give it a little more gas, grit your teeth in a determined way... it won't matter if the Earth is literally splitting open behind you or you are trying to ascend up the leading slope of a tsunami. Buildings can be falling around you... just tilt the planes wings and push that handle-thingy harder.
You're going to be fine.
Wait For It
Did your plane just get engulfed by flames and smoke as it was trying to take off? Sit back and have a drink. Give it a count of three and your plane will burst out of danger and fly to safety. Did someone in your party just spend 3 full minutes underwater? I know that it SEEMS like they should have run out of air and died, but not to worry.
If the person you are waiting on is an authority figure like a dad or ex-cop or a plucky scientist... just wait. A hand will reach up and grasp the edge of the crevice or a head will break the surface of the water with a gasp. Totally fine.
Just wait for it.
