Major catastrophic events that follow predictable patterns and haven’t happened in decades.

Nature operates on timescales that make human planning look adorably short-sighted. While we worry about quarterly earnings and election cycles, the Earth quietly builds up geological pressures that release catastrophically every few hundred years.
Scientists can read these patterns in rock layers, ice cores, and historical records with disturbing precision—massive earthquakes that strike every 300 years, supervolcanic eruptions that follow 600,000-year cycles, and mega-tsunamis that reshape coastlines every few centuries.
The terrifying part isn’t that these disasters will happen; it’s that many of them are statistically overdue based on historical patterns. Some have been building pressure for so long that seismologists, volcanologists, and other disaster scientists are essentially waiting for the other shoe to drop.
