to geologists the earth is just a bunch of play-dough. squishing and wrinkling, being wiped away and cut into by water...I wonder if there are any simulators for this kind of thing?I'd like to mess with the parameters and see what happens.

@futurebird Will earthquake simulations scratch the itch? You can play with different earthquake scenarios here:https://earthquake.usgs.gov/education/shakingsimulations/hayward/I had thought quakes were like a ripple in a pond, when they vary considerably based on where they rupture and which direction they head.The hills of the Bay Area will likely change to a degree. 10 ft of rupture along the fault, the biggest fault rupture risk in the world based on population density. There is a distinct possibility that when the big one hits LA the heavy shaking will miss the population areas. Roughly 50/50 chance. Like a category 5 hurricane just missing landfall at a big populated city or hitting dead on. But we won't know rupture direction which until it hits.

@futurebird There are some lab demos for this sort of thing.From Earth, Planetary, and Space Sciences at UCLA; where I postdoc'd:https://www.universityofcalifornia.edu/news/make-it-rain-check-out-augmented-reality-teaching-sandbox

@futurebird I mean they also think the heat of radioactive decay and the heat of gravitational compression are quite important. Radioactive playdough is probably not recommended.

@futurebird huh, I've been to that canyon. My brother, who was driving, even pulled over and commented and the rocks. (He's not a geologist, he's an artist, any change in color is meaningful to him.) But it was long ago, and neither of us knew much about geology in those days, although we did grasp that something had been lost in that unconformity.

@futurebird Having watched some of his content before, this makes me want to become a geologist. So accessible lectures and such a great and calm host

@leadore I really admire and try to emulate his teaching style. So much love for the topic and he's so committed to making it as dead simple as possible because you get the sense he *really* wants you to understand.
