@cutawaynature: A volcano erupts — and the debris avalanche it sends down the mountainside blocks the river below completely. Behind the new dam, a lake begins to rise. Days pass. The rockpile dries and settles... until the pressure finds a crack. Watch a single eruption reshape an entire valley, one stage at a time, in cross-section. #cutaway #crosssection #geology #nature #learnontiktok #satisfying #asmr
