List Rules Only disaster movie science -- geology, astronomy, meteorology, physics, etc.

Hollywood has no time for science! It's too slow/too fast, too dangerous/too benign, and mostly too complicated to be bothered with on the big screen. Disaster movies are the worst offenders of them all.

If you have your fave bad-science moments in any disaster film at all, add it! I want more! MORE!

You Can Survive the Blast of a SuperVolcano

The Yellowstone super volcano has previously erupted three times with a force up 2,500 times of Mount St. Helens... an eruption that generated a blast equal to 27,000 Hiroshima-sized nuclear weapons. This yellowstone eruption of the past covered almost all of the current U.S. in ash.

Now, let's sit back together, steeple our fingers thoughtfully and remember how John Cusack stood there with his kid and watched as the Caldera in 2012 blew. Not only did the force of the blast not completely liquify the pair of them, but they weren't even deafened. Or blinded.

Fun fact: RVs can outrun the blast radius of an Extinction Level Event like this. I bet your grandpa feels much more justified in his retirement purchase now.

Lava's Not Really That Hot

Ha ha, oh Lava. That? No problem. If you have watched Volcano or Dante's Peak, you know you can totally hang out behind the safety of concrete construction barricades and have a coffee. Or climb out over it on a ladder. It might make you sweat or something. But it's not like its around 1500 degrees Fahrenheit. 

Sure, people can collapse from heat exhaustion when it hits 120 degrees, but lava is different. Apparently. Did you know you can drive over it and only get some popped tires? Pierce Brosnan did it, so can you!

Say, for example, there's this magic super storm and the "eye" of it is sucking air out of the chilly troposphere. Well, supposedly if you were in that "eye," it would get really cold. Because the Troposphere reaches temps of 60 degrees F (OMG! I need a light sweater!) to -60 degrees F at the coldest. Apparently, that's like liquid nitrogen or something. Don't tell the folks who live in Alaska.

Even if 60 degrees were actually THAT cold, it turns out that molecules of air compress as they come down, which would mean they would warm adiabatically. The air molecules are closer together nearer to Earth because of this thing called "gravity." More densely populated molecules means more kinetic energy, which means warmth. So... there's that.

Sure, the magic science of the Day After Tomorrow tells us that "the air is descending too fast to warm up," but that's hilariously stupid. That's like saying the laws of physics are just a suggestion. A guideline, if you will. This is like saying that "speed" beats all natural laws. Kind of like how, if you run fast enough, you can outrun air.

P.S. A couple of wooden doors will stop that magic science air "cold" in its tracks. Haha... see what I did there?

Earthquake Cracks Think They're People

I guess some earthquakes are sentient? And hold grudges? How else do you explain their uncanny ability to sense a moving vehicle or running person and follow just behind them? 

Not only do these Krazy Kracks do vengeful stuff like chase people, but in real life they just don't really happen like that. Earthquake movies like 10.5 and San Andreas are big fans of monstrous cracks opening up so cars and people and stuff can fall in... but in the case of a strike-slip fault (like the San Andreas) these things don't happen. The two sides of the fault are scraping against each other in opposite directions - - the friction is what causes the shaking. If the earth pulled apart like in the photo above there would be no friction. And no shaking. But it remains the go-to visual for hollywood when they want to depict earthquakes.

There are divergent plate boundaries that pull away from each other, but these are slow movements that occur where continental plates meet and create massive rift valleys. Like in Africa and in the middle of the Atlantic.
