A North-to-South Split Through Mexico? Why It Would Never Happen A giant crack slicing Mexico from top to bottom looks wild — but here’s why it’s impossible: • Tectonics don’t allow it – Mexico’s crust is complex but stable in the interior. • Crust bends, doesn’t snap – Stress is released in earthquakes, not continent-wide splits. • No single fault line spans the country – There’s no natural weakness for a full north-south tear. Epic to imagine, but pure geology says nope. #EarthScience #Geology
