Hollywood has a quiet rule: when the world's about to end, the scientist who saves it usually isn't the physicist. It's the geologist. Rock hammer in one hand, asbestos sample in the other. A geoscientist ranks fiction's most famous rock nerds. 🧵Let's explore some of the most famous ones #geology

The deepest hole ever drilled gets 0.2% of the way to Earth's centre. How do we know what's inside the Earth? Inge Lehmann found the inner core in 1936 using cards filed in oatmeal boxes. She never said it was solid. Proof of that came in 1971. geoscopy.com/how-earthqua... #geology

Venezuela didn’t get one major earthquake. It got two. A M7.2 struck first. Just 39 seconds later, a larger M7.5 hit almost the same patch of crust. That’s not a normal aftershock. It’s a seismic doublet, and the second quake was bigger. Read it on geoscopy.com. #geology #venezuela #earthquake
